Introduction Methods Results Discussion and Conclusions This study aimed to assess the impact of the implementation of legally sanctioned supervised consumption sites (SCS) in the Canadian province of Ontario on opioid‐related deaths, emergency department (ED) visits and hospitalisations at the public health unit (PHU) level.Monthly rates per 100,000 population of opioid‐related deaths, ED visits and hospitalisations for PHUs in Ontario between December 2013 and March 2022 were collected. Aggregated and individual analyses of PHUs with one or more SCS were conducted, with PHUs that instituted an SCS being matched to control units that did not. Autoregressive integrated moving average models were used to estimate the impact of SCS implementation on opioid‐related deaths, ED visits and hospitalisations.Twenty‐one legally sanctioned SCS were implemented across nine PHUs in Ontario during the study period. Interrupted time series analyses showed no statistically significant changes in opioid‐related death rates in aggregated analyses of intervention PHUs (increase of 0.02 deaths/100,000 population/month; p = 0.27). Control PHUs saw a significant increase of 0.38 deaths/100,000 population/month; p < 0.001. No statistically significant changes were observed in the rates of opioid‐related ED visits in intervention PHUs (decrease of 0.61 visits/100,000 population/month; p = 0.39) or controls (increase of 0.403 visits; p = 0.76). No statistically significant changes to the rates of opioid‐related hospitalisations were observed in intervention PHUs (0 hospitalisations/100,000 population/month; p = 0.98) or controls (decrease of 0.05 hospitalisations; p = 0.95).This study did not find significant mortality or morbidity effects associated with SCS availability at the population level in Ontario. In the context of a highly toxic drug supply, additional interventions will be required to reduce opioid‐related harms. [ABSTRACT FROM AUTHOR]

Reducing the carbon intensity of human well-being (CIWB) is a potential form of climate action. We conduct a preliminary analysis of the effects of economic growth and income inequality on the CIWB of Canada's provinces, and find that both increase CIWB in this sub-national context. We also find that their effects are symmetrical, meaning that positive and negative changes in economic growth and income inequality result in the same proportional changes in CIWB. Therefore, and while incredibly difficult to do, it is possible that efforts to reduce income inequality and economic growth are potential pathways to reducing CIWB. [ABSTRACT FROM AUTHOR]

Purpose: This pan-Canadian study examines the information practices of STEM-trained immigrant women to Canada as they navigate workfinding and workplace integration. Our study focuses on a population of highly skilled immigrant women from across Canada and uses an information practice lens to examine their lived experiences of migration and labour market integration. As highly trained STEM professionals in pursuit of employment, our participants have specific needs and challenges, and as we explore these, we consider the intersection of their information practices with government policies, settlement services and the hiring practices of STEM employers. Design/methodology/approach: We conducted a qualitative study using in-depth interviews with 74 immigrant women across 13 Canadian provinces and territories to understand the nature of their engagement with employment-seeking in STEM sectors. This article reports the findings related to the settlement and information experiences of the immigrant women as they navigate new information landscapes. Findings: As immigrants, as women and as STEM professionals, the experiences of the 74 participants reflect both marginality and privilege. The reality of their intersectional identities is that these women may not be well-served by broader settlement resources targeting newcomers, but neither are the specific conventions of networking and job-seeking in the STEM sectors in Canada fully apparent or accessible to them. The findings also point to the broader systemic and contextual factors that participants have to navigate and that shape in a major way their workfinding journeys. Originality/value: The findings of this pan-Canadian study have theoretical and practical implications for policy and research. Through interviews with these STEM professionals, we highlight the barriers and challenges of an under-studied category of migrants (the highly skilled and "desirable" type of immigrants). We provide a critical discussion of their settlement experiences and expose the idiosyncrasies of a system that claims to value skilled talent while structurally making it very difficult to deliver on its promises to recruit and retain highly qualified personnel. Our findings point to specific aspects of these skilled professionals' experiences, as well as the broader systemic and contextual factors that shape their workfinding journey.

The concept of national boundaries has been employed extensively in the social sciences, with most research focusing on the host society's perspective. This study innovates by measuring immigrants’ perceptions of how boundaries of their host nation are drawn and examining how such perceptions impact their national identifications in a multinational context, more specifically in the province of Quebec in Canada. It relies on a stratified sample of first- (n = 1129) and second-generation immigrants (n = 1286) as well as non-immigrants (n = 1472). We show that boundary perceptions impact the availability and attractiveness of different identity options, including identification with Quebec, the country of origin, and Canada. First, while perceptions of ascriptive boundaries to Quebec push first- and second-generation immigrants away from Quebec identity, the reactive effect of strengthening identification with the country of origin and Canada is limited. Second, although the second generation perceives Quebec boundaries as more ascriptive than the first generation, it is not more strongly impacted by their boundary perceptions in their identifications. Third, perceptions of attainable boundaries promote all three national identifications, but only for the first generation. Finally, we demonstrate that attention to boundary perceptions adds important explanatory leverage beyond the impact that discrimination has on national identifications. [ABSTRACT FROM AUTHOR]

The orange wheat blossom midge, Sitodiplosis mosellana (Géhin) (Diptera: Cecidomyiidae), is a significant wheat pest in the Prairie Provinces of Canada and northern regions of the USA. Wheat phenology plays a critical role in wheat midge oviposition. We hypothesized that S. mosellana oviposition behaviour is influenced by volatile organic compounds (VOCs) emitted by wheat at two adjacent wheat growth stages: preanthesis and postanthesis. A higher number of S. mosellana eggs laid on preanthesis than postanthesis spikes in an oviposition choice experiment using the susceptible spring wheat cultivar 'Roblin'. In preanthesis, wheat emitted higher amounts of Z-3-hexenyl acetate (Z3-06:OAc) than at the postanthesis stage. Higher amounts of methyl ketones such as 2-tridecanone, 2-pentadecanone, and 2-undecanone were emitted by wheat in the postanthesis stage and these VOCs were sensitive to S. mosellana antennae used in the Gas Chromatography-Electroantennographic Detection. Females were attracted to synthetic Z3-06:OAc but were deterred by 2-tridecanone relative to the solvent control in the vertical Y-tube olfactometer. 2-Undecanone and 2-pentadecanone did not show any attractiveness or deterrence. In a no-choice oviposition experiment, fewer eggs were laid in preanthesis wheat exposed to a synthetic VOC blend of Z3-06:OAc, 2-undecanone, 2-tridecanone, and 2-pentadecanone at the concentrations released by postanthesis spikes. This study shows that the reduction of Z3-06:OAc, in the VOC mix, and possibly the increase in 2-tridecanone, are likely responsible for the reduction in oviposition on postanthesis wheat. These results elucidate for the first time the role of specific VOCs mediating S. mosellana oviposition in preanthesis and postanthesis wheat. [ABSTRACT FROM AUTHOR]

Infertility is a common diagnosis: in its original, heteronormative definition, it is known to impact about 1 in 6 couples worldwide. Governments across Canada and beyond have been increasingly providing support for those undergoing fertility treatment, and BC is the most recent province to announce funding, beginning in 2025. As the amount of proposed funding is not sufficient to cover treatment for all who seek it, we look to examples from other provinces and countries to guide us in forming criteria that balance fair access with likelihood of successful treatment. A majority of Canadian provinces currently provide publicly funded fertility care, albeit with highly variable models. Quebec previously introduced a model with generous coverage, including up to three cycles of in vitro fertilization (IVF), along with medications, associated procedures, and embryo transfers for each live birth. Due to high costs, this funding was removed and reintroduced in 2021 with a more restrictive model, as well as age cutoffs for IVF and embryo transfers. In Ontario, the current funding model was introduced in 2015 and covers intrauterine insemination cycles and one cycle of IVF in patients younger than 43 years of age. Other provinces have offered a fertility treatment tax credit. While the BC announcement stated that one cycle of IVF with medications will be covered, the details on how this finite resource will be distributed are still unclear. We hope BC will consider the lessons learned from other provinces and countries and implement a program that is fair and accessible to those who need it. [ABSTRACT FROM AUTHOR]

During the past 30 years, research on policy analytical capacity's multidimensional nature and the evolution of policy advisory systems (PASs) has both increased knowledge of these processes and structures and opened new avenues of inquiry. While it is clear that changes in PASs in many countries have occurred ‐ featuring processes such as the increased externalisation and politicisation of policy advice ‐ studies of changes among the roles played by core policy professionals in advice provision have lagged. One aspect of this question concerns the nature and extent of changes in this 'forgotten fundamental' of advice systems related to how these professionals are arrayed within 'policy shops'—that is organisational units identified in the 1960s and 1970s as the main organisational home of policy professionals in government. Whether or not such shops have changed from the central‐integrated model identified in early studies and, if so, how, remain outstanding and foundational questions. Recent research in Canada has mapped the distribution of policy professionals at the central and provincial level and found more types of analysts and venues than in earlier eras— which range from the 'classical' integrated policy shops of the 1960s and 1970s which remain in central agencies and single‐purpose line departments to the much more 'distributed' patterns found in many departments dealing with multiple or complex controversial issues. Using Canadian data, this study outlines the development of these organisational types and their distribution in government and discusses the implications of these changes for better understanding the work, and needs, of core professionals in policy advice systems.. Points for practitioners: 'Policy professionals' or public employees specifically tasked with policy analysis in government are key players in policy advisory systems despite the addition of more external and internal actors in policy advice systems in recent years.How these advisors and analysts are organised in government, whether they work in clusters or small groups, and how they interact with other civil servants and policy‐makers are a key determinant of their activities and influence in policy‐making.In the policy sciences, work in the 1960s and 1970s established 'the policy shop', that is relatively small centrally located organisational units employing mainly policy analysts, as the main home of policy professionals in government. These units often enjoyed a monopoly in analysis and played a key role in policy‐making. However, research on these organisations has not kept up with changes in advisory relations within and outside of governments and the impact such changes have had on the influence and activities of core professionals.Recent work by the authors looking at the large Canadian province of Ontario has identified more than a single type of arrangement of analysts in the current era. This paper expands this analysis to both small and large jurisdictions in Canada, including the federal government, and develops two detailed case studies of the current organisation of policy professionals in smaller central agencies like Ministries of Justice as well as in larger omnibus Ministries of the Environment.The study finds a 'distributed' model of policy shops—in which multiple policy units exist throughout the agency—to be dominant in both cases and in all the governments examined and suggests this is now the new normal, replacing the dominance of the older more integrated central shop model. The predominance of the distributed model contributes to the fragmentation of policy advice already underway in government due to the growth in the number of external advisors such as consultants and think tanks, and internal ones such as political staffers.

• Canadian E-waste recycling data from 2012 to 2020 are systematically assessed. • Regression and Mann-Kendall analyses are used to quantify the temporal trends. • Both collection points and stewardship organizations have grown exponentially. • The role of public awareness on e-waste recycling varied between provinces. • Operational expenditure and revenue on stewardship resilience should be monitored. Electronic waste recycling companies have proliferated in many countries due to valuable materials present in end-of-life electronic and electrical equipment. This article examined the business characteristics and management performance of Electronic Products Recycling Association (EPRA), a Canadian nationwide electronic product stewardship organization. The organization's annual performance reports, from 2012 to 2020, for nine Canadian provinces in which it currently operates were aggregated and analyzed. Temporal analysis using regression and Mann-Kendall tests were employed, and five characteristics of EPRA's business were analyzed, including e-waste products collected, number of drop-off locations, efforts to build public awareness, operating expenses, and growth of e-waste stewardship. Results show a decline in the amount of e-waste collected across the provinces, except in New Brunswick, which started its program in 2017. The Mann-Kendall test revealed declining temporal trends in most provinces. Although the collection/drop off sites and stewardship organizations increased astronomically over the study period in Canada, the amounts of e-waste collected decreased. We found that public awareness generally did not increase the amount of e-waste collected, and these campaigns only appeared to be effective in jurisdictions with good accessibility of e-waste recycling. Processing cost accounted for the majority of the e-waste management budget in Canada, and different factors affected the financial success of the stewards differently. [ABSTRACT FROM AUTHOR]

Introduction: The use of osimertinib in the first-line (1L) setting is an effective treatment option for sensitizing EGFR-mutations (EGFRm+) and has significantly altered the standard of care practice for EGFRm+ disease in Canada. Unfortunately, acquired resistance to osimertinib is almost universal, and outcomes are disparate. Post-progression treatment patterns and the outcome of real-world Canadian EGFRm+ patients receiving 1L osimertinib were the focus of this retrospective review. Methods: The Glans-Look Lung Cancer Research database was used to identify and collect demographic, clinical, treatment, and outcome data on EGFRm+ patients who received 1L osimertinib in the Canadian province of Alberta between 2018 and 2022. Results: A total of 150 patients receiving 1L osimertinib were identified. In total, 86 developed progressive disease, with 56 (65%) continuing systemic therapy, 73% continuing osimertinib, and 27% switching to second-line (2L) systemic therapy. Patients were similar both in clinical characteristics at 1L osimertinib initiation and patterns of treatment failure at progression; those continuing 1L osimertinib post-progression had a longer time to progression (13.5 vs. 8.8 months, p = 0.05) and subsequent post-osimertinib initiation survival (34.7 vs. 22.8 months, p = 0.11). Conclusions: The continuation of osimertinib post-progression is an effective disease management strategy for select real-world EGFRm+ patients, providing continued clinical benefit, potentially due to different underlying disease pathogenesis.

Venetoclax is a first-in-class B-cell lymphoma-2 (BCL-2) inhibitor approved as continuous monotherapy and in combination with rituximab as fixed-treatment duration for relapsed and refractory chronic lymphocytic leukemia (R/R CLL). DEVOTE was a 24-week, multicenter observational study (NCT03310190) evaluating the safety, healthcare resource utilization (HCRU) and health-related quality of life (HRQoL) of patients initiating venetoclax for R/R CLL in Canada. Overall, 89 patients received 1 dose of venetoclax; 80% had prior exposure (42% resistant) to ibrutinib. Biochemical tumor lysis syndrome (TLS) occurred in five patients. We observed differences in hospitalization across Canadian provinces including in patients at low risk for TLS with no clear impact on TLS incidence. Additionally, a rapid and sustained improvement in several domains of HRQoL was observed during venetoclax initiation. Early adoption of venetoclax was mainly for R/R CLL patients with few treatment options; nonetheless, acceptable toxicity and a positive impact on HRQoL were observed. [ABSTRACT FROM AUTHOR]

This Special Section explores the interplay between Indigenous peoples, industry, and the state in five proposed and active mining projects in Canada and Sweden. The overall aim is to identify factors shaping the quality of Indigenous community-industry-state interactions in mining and mine development. An ambition underlying the research is to develop knowledge to help manage mining related land-use conflicts in Sweden by drawing on Canadian comparisons and experience. This paper synthesizes the comparative research that has been conducted across jurisdictions in three Canadian provinces and Sweden. It focuses on the interplay between the properties of the governance system, the quality of interaction and governance outcomes. We combine institutional and interactive governance theory and use the concept of governability to assess how and why specific outcomes, such as mutually beneficial interaction, collaboration, or opposition, occurred. The analysis suggests there are measures that can be taken by the Swedish Government to improve the governability of mining related issues, by developing alternative, and more effective, avenues to recognize, and protect, Sámi rights and culture, to broaden the scope and increase the legitimacy and transparency of the EIAs, to raise the quality of interaction and consultation, and to develop tools to actively stimulate and support collaboration and partnerships on equal terms. Generally, we argue that Indigenous community responses to mining must be understood within a larger framework of Indigenous self-determination, in particular the communities' own assessments of their opportunities to achieve their long-term objectives using alternative governing modes and types of interactions.

Background: The drug toxicity crisis continues to accelerate across Canada, with rapid increases in opioid-related harms following the onset of the COVID-19 pandemic. We sought to describe trends in the burden of opioid-related deaths across Canada throughout the pandemic, comparing these trends by province or territory, age, and sex. Methods: We conducted a repeated cross-sectional analysis of accidental opioid-related deaths between Jan. 1, 2019, and Dec. 31, 2021, across 9 Canadian provinces and territories using aggregated national data. Our primary measure was the burden of premature opioid-related death, measured by potential years of life lost. Our secondary measure was the proportion of all deaths attributable to opioids; we used the Cochrane–Armitage test for trend to compare proportions. Results: Between 2019 and 2021, the annual number of opioid-related deaths increased from 3007 to 6222 and years of life lost increased from 126 115 to 256 336 (from 3.5 to 7.0 yr of life lost per 1000 population). In 2021, the highest number of years of life lost was among males (181 525 yr) and people aged 30–39 years (87 045 yr). In 2019, we found that 1.7% of all deaths among those younger than 85 years were related to opioids, rising to 3.2% in 2021. Significant increases in the proportion of deaths related to opioids were observed across all age groups (p < 0.001), representing 29.3% and 29.0% of deaths among people aged 20–29 and 30–39 years in 2021, respectively. Interpretation: Across Canada, the burden of premature opioid-related deaths doubled between 2019 and 2021, representing more than one-quarter of deaths among younger adults. The disproportionate loss of life in this demographic group highlights the critical need for targeted prevention efforts. [ABSTRACT FROM AUTHOR]

Slave Province in Canada is an Archean granite–supracrustal terrane at the northwestern corner of the Canadian Shield. It is bordered by the Thelon–Taltson orogen (2.0 to 1.9 Ga) to the southeast and the Wopmay orogen (1.9 to 1.8 Ga) to the west. Acasta gneisses, exposed in the westernmost Slave Province, and the Wopmay rocks, located close to the gneisses, were systematically collected for K–Ar and laser step-heating 40Ar/39Ar single-crystal analyses of the biotite and amphibole. The K–Ar biotite ages of the four Wopmay samples range from 1816 ± 18 Ma to 1854 ± 26 Ma. The 40Ar/39Ar biotite analyses of the three Wopmay samples yield plateau ages of 1826 ± 21 Ma, 1886 ± 13 Ma, and 1870 ± 18 Ma. These ages fall within the reported U–Pb zircon age range of the Wopmay orogen. The K–Ar biotite ages of the fifteen Acasta gneisses range from 1779 ± 25 Ma to 1877 ± 26 Ma, except for one younger sample (1711 ± 25 Ma). The 40Ar/39Ar analyses of the biotite crystals from three samples give the plateau ages of 1877 ± 8 Ma, 1935 ± 14 Ma, and 1951 ± 11 Ma. The K–Ar amphibole ages from twelve samples range from 1949 ± 19 Ma to 1685 ± 25 Ma. Two samples of them give ages older than the zircon U-Pb age of Hepburn plutons. The 40Ar/39Ar analyses of the amphibole crystals show varied age relations. The two samples give plateau ages of 1814 ± 22 Ma and 1964 ± 12 Ma. Some samples exhibit apparent old ages of ~2000 Ma in the middle temperature fractions. These old fractions result from the amphibole crystals, originally formed in the Archean, being affected by the thermal events during the Wopmay orogeny but not fully resetting. These observations suggest that the K–Ar system ages of the biotite and amphibole in the Archean Acasta gneiss were rejuvenated during the Paleoproterozoic ages. The Discussion explores the possibility that the heat source rejuvenating the K–Ar system ages may have arisen due to asthenospheric extrusion into the wedge mantle, a process likely triggered by subduction rollback.

Despite the ubiquity of the concept of the complete community or neighborhood in Canadian planning practice and the recent spread of the idea in the United States, few scholars have examined the idea's development and implications. Based on a content and thematic analysis of 102 plans and policies representing all Canadian provinces and territories, along with 205 planner interviews, I argue that the complete community represents an integrative, scalable, and flexible planning theory originating from practice. Borrowing principles from other theories (such as smart growth and sustainable development), practitioners built the complete community idea bottom-up, as a persuasive rhetorical vehicle for describing planning intentions and justifying higher densities in positive ways. Contemporary planning values increasing urban densities, mix, and walkability. Here I illustrate how planners adapted to community resistance to ideas generated by external experts—and to efforts to increase growth and densities—by articulating a socially and politically positive option for urban transformation. The complete community concept places a halo over density, promising vibrancy and livability. [ABSTRACT FROM AUTHOR]

The development and implementation of extended producer responsibility (EPR) policies to manage e‐waste provide multilevel governance frameworks for achieving greater material circularity. However, the roles and responsibilities that are allocated to various stakeholders under these policies, which are crucial for program effectiveness, often vary across jurisdictions, and consensus is lacking about the best types of relationships and collaboration that should govern municipalities' contributions to EPR programs. Against this backdrop, and since this issue is poorly researched, we conducted an empirical investigation to identify the main drivers and barriers influencing municipalities' collaboration with an e‐waste EPR program in a Canadian province where municipalities are free to decide whether or not to engage with the program. Based on our study, we explore policy implications for similar programs in other jurisdictions, and propose questions for further research. Our findings identify key motivations for collaboration, including perceived program legitimacy, program funding, and logistical efficiencies. Conversely, a lack of program transparency, failure to support local employment, a focus on recycling instead of reuse, and limited program scope are identified as disincentives to program participation. Policymaking for e‐waste management and circularity need to consider municipalities' interests and contributions to ensure successful implementation. [ABSTRACT FROM AUTHOR]

Background:Child and youth mental health problems represent a substantial burden of illness in Canada, with appropriate services only inconsistently available. Charitable organizations, such as Kids Help Phone (KHP), are, therefore, crucial to filling system gaps by offering 24/7 phone, chat, texting, and peer-to-peer services. Methods:We describe the services provided by KHP, the volume of use for each service, and compare usage across Canada's provinces and territories for a 5-year period from January 2018 to December 2022. Trends seen during the COVID-19 pandemic are highlighted. Results:More than 1.5 million total number of conversations were held across texting, chat, and phone services over 5 years. Considerable growth is demonstrated between 2018 and 2022, and many of the highest peaks in volume occurred in March or April of 2020, the onset of the COVID-19 pandemic. The highest proportional volumes were consistently from the northern territories. Discussion:KHP cannot provide specialized or repeat services, nor can it alone meet the scale of unmet youth mental health needs across the country. Nonetheless, KHP plays a pivotal role in the Canadian mental health system. Efforts to understand the role that KHP and other e-mental health services like it play within the national mental health landscape should be intensified to aid in understanding unmet needs, identify system gaps, and make needed enhancements.

In the era of (re)legalisation of medicinal and recreational cannabis, accidental and intentional exposure to edibles, cannabis-infused food products, has increased substantially. However, there is particular concern regarding younger age groups. Most concerning is the increase in hospitalisations. According to a study by Myran et al. (1), provinces in Canada, where the sale of edibles is permitted, saw an increase in paediatric poisonings due to unintentional consumption of edibles. Similar trends have been observed in "legalised states" in the US, such as Colorado (2). The impact of using cannabis at an early age, but particularly the impact of accidental exposure to high THC quantities, may have negative mental or physical health outcomes. Whilst regulatory restrictions vary significantly from one legalised region to another, it is difficult to identify a best practice. The aim of this study is to identify and discuss new and existing risk mitigation strategies to give guidance to policymakers. Furthermore, practical aspects, such as compliance (e.g. audits by authorities), are discussed. It is noted that edibles have been around much longer than recent political attempts to regulate them.

Purpose: The incidence of childhood-onset inflammatory bowel disease (IBD) is rising. We described variation in health services utilization and need for surgery among children with IBD between six and 60 months following IBD diagnosis across Canadian pediatric centers and evaluated the associations between care provided at diagnosis at each center and the variation in these outcomes. Patients and Methods: Using population-based deterministically-linked health administrative data from four Canadian provinces (Alberta, Manitoba, Nova Scotia, Ontario) we identified children diagnosed with IBD < 16 years of age using validated algorithms. Children were assigned to a pediatric center of care using a hierarchical approach based on where they received their initial care. Outcomes included IBD-related hospitalizations, emergency department (ED) visits, and IBD-related abdominal surgery occurring between 6 and sixty months after diagnosis. Mixed-effects meta-analysis was used to pool results and examine the association between center-level care provision and outcomes. Results: We identified 3784 incident cases of pediatric IBD, of whom 2937 (77.6%) were treated at pediatric centers. Almost a third (31.4%) of children had ≥ 1 IBD-related hospitalization and there were 0.66 hospitalizations per person during follow-up. More than half (55.8%) of children had ≥ 1 ED visit and there were 1.64 ED visits per person. Between-center heterogeneity was high for both outcomes; centers where more children visited the ED at diagnosis had more IBD-related hospitalizations and more ED visits during follow-up. Between-center heterogeneity was high for intestinal resection in Crohn's disease but not colectomy in ulcerative colitis. Conclusion: There is variation in health services utilization among children with IBD and risk of undergoing intestinal resection in those with Crohn's disease, but not colectomy among children with ulcerative colitis, across Canadian pediatric tertiary-care centers. Improvements in clinical care pathways are needed to ensure all children have equitable and timely access to high quality care. Plain Language Summary: Inflammatory bowel disease (IBD) is a chronic health condition of the gastrointestinal system, which is becoming more common in children. They require lifelong treatment and receiving high quality care is important for preventing complications. We determined if outcomes of children with IBD was different across Canada. We also tested if differences in care at diagnosis was related to outcomes. More than three-quarters of children with IBD were treated at pediatric hospitals. Children treated at some hospitals were more likely to be hospitalized and visit the emergency room when compared to children treated at other hospitals. Children with Crohn's disease (one type of IBD) were more likely to have surgery at some hospitals when compared to children treated at other hospitals. We should improve care to make sure children living with IBD have timely access to high quality specialist care. [ABSTRACT FROM AUTHOR]

Background: The spread of SARS-CoV-2 has been studied at unprecedented levels worldwide. In jurisdictions where molecular analysis was performed on large scales, the emergence and competition of numerous SARS-CoV-2lineages have been observed in near real-time. Lineage identification, traditionally performed from clinical samples, can also be determined by sampling wastewater from sewersheds serving populations of interest. Variants of concern (VOCs) and SARS-CoV-2 lineages associated with increased transmissibility and/or severity are of particular interest. Method: Here, we consider clinical and wastewater data sources to assess the emergence and spread of VOCs in Canada retrospectively. Results: We show that, overall, wastewater-based VOC identification provides similar insights to the surveillance based on clinical samples. Based on clinical data, we observed synchrony in VOC introduction as well as similar emergence speeds across most Canadian provinces despite the large geographical size of the country and differences in provincial public health measures. Conclusion: In particular, it took approximately four months for VOC Alpha and Delta to contribute to half of the incidence. In contrast, VOC Omicron achieved the same contribution in less than one month. This study provides significant benchmarks to enhance planning for future VOCs, and to some extent for future pandemics caused by other pathogens, by quantifying the rate of SARS-CoV-2 VOCs invasion in Canada.

Canadian provinces are required to regulate their power sectors using carbon pricing systems that meet national minimum stringency standards, which are set by the federal government. A diverse set of systems has emerged as a result. However, there has been limited assessment of how different pricing mechanisms impact the evolution of Canada's electricity system. To address this gap, we use an electricity system planning model called COPPER and a scenario-based approach to assess if, and to what extent, different policy regimes impact power sector greenhouse gas emissions and costs. Our results show that carbon pricing systems currently in place lead to significant carbon reductions over the long term, provided that free emissions allocations are reduced. However, the cost-optimal pathway for the power sector differs across provinces depending on the carbon pricing mechanism. Some provinces achieve least-cost emissions reductions by switching from high-carbon technologies to renewables, while others are better served by replacing high-carbon technologies with low-carbon fossil fuel alternatives. Further, provinces that implement cap-and-trade systems may affect the transitions of interconnected jurisdictions. Power sector climate policy design should reflect the heterogeneity of available assets, resources, and neighbouring approaches. [ABSTRACT FROM AUTHOR]

Background: Eating disorders have one of the highest mortality rates among psychiatric illnesses. Timely intervention is crucial for effective treatment, as eating disorders tend to be chronic and difficult to manage if left untreated. Clinical practice guidelines play a vital role in improving healthcare delivery, aiming to minimize variations in care and bridge the gap between research and practice. However, research indicates an active guideline implementation approach is crucial to effective uptake. Methods: Mixed methods will be used to inform and evaluate our guideline implementation approach. Semi-structured focus groups will be conducted in each of the eight provinces in Canada. Each focus group will comprise 8–10 key stakeholders, including clinicians, program administrators, and individuals with lived experience or caregivers. Qualitative data will be analyzed using conventional content analysis and the constant comparison technique and the results will be used to inform our implementation strategy. The study will then evaluate the effectiveness of our implementation approach through pre- and post-surveys, comparing changes in awareness, use, and impact of the guidelines in various stakeholder groups. Discussion: Through a multifaceted implementation strategy, involving the co-creation of educational materials, tailored training, and context-specific strategies, this study intends to enhance guideline uptake and promote adherence to evidence-based practices. Our study will also contribute valuable information on the impact of our implementation strategies. This protocol outlines a comprehensive research study aimed at evaluating an implementation approach for the uptake of the Canadian Practice Guidelines for Treating Children and Adolescents with Eating Disorders across Canada. Eating disorders (EDs) have a significant impact on mental and physical health, necessitating evidence-based and timely interventions. To address gaps in service, we propose to use focus groups to identify barriers, facilitators, and implementation strategies for guideline uptake. We will engage stakeholders, including clinicians, administrators, and individuals with lived experience, to co-create tailored educational materials which will then be disseminated. The impact of the implementation approach will be evaluated through pre- and post-implementation surveys. This study aims to enhance the availability and utilization of evidence-based treatments for children and adolescents with EDs, ensuring equitable and improved care nationwide.

With limited phosphorus (P) supplies, increasing P demand, and issues with P runoff and pollution, developing an ability to reuse the large amounts of residual P stored in agricultural soils is increasingly important. In this study, we investigated the potential for residual soil P to maintain crop yields while reducing P applications and losses in Canada. Using a P cycling model coupled with a soil P dynamics model, we analyzed soil P dynamics over 110 years across Canada's provinces. We found that using soil residual P may reduce mineral P demand as large as 132 Gg P year−1 (29%) in Canada, with the highest potential for reducing P applications in the Atlantic provinces, Quebec, Ontario, and British Columbia. Using residual soil P would result in a 21% increase in Canada's cropland P use efficiency. We expected that the Atlantic provinces and Quebec would have the greatest runoff P loss reduction with use of residual soil P, with the average P loss rate decreasing from 4.24 and 1.69 kg ha−1 to 3.45 and 1.38 kg ha−1, respectively. Ontario, Manitoba, and British Columbia would experience relatively lower reductions in P loss through use of residual soil P, with the average runoff P loss rate decreasing from 0.44, 0.36, and 4.33 kg ha−1 to 0.19, 0.26, and 4.14 kg ha−1, respectively. Our study highlights the importance of considering residual soil P as a valuable resource and its potential for reducing P pollution. [ABSTRACT FROM AUTHOR]

The package PbIso is a free and open R toolbox for commonly used calculations and plots of Pb–Pb isotope data and for generating Pb evolution models. In this paper, we review Pb isotope systematics and the calculations that are commonly used, such as model age, model source μ (238U/204Pb), time-integrated κ (232Th/238U), and initial Pb isotope ratios. These equations are implemented into R functions in the package PbIso. In addition, functions are provided for generating Pb evolution models, paleoisochrons, and isochrons. This allows users to apply calculations to their data in a straightforward way while providing transparency and flexibility of the calculations used. We have implemented some basic features of the PbIso package into an online shiny R application (see https://shereearmistead.github.io/software/pbiso), which makes it easy for users without any R experience to use these calculations with their own data and to generate plots. We have provided a case study from the Superior Province in Canada, showing how different Pb evolution models can be generated in PbIso and compared to Pb isotope data. [ABSTRACT FROM AUTHOR]

Lyme disease cases reported in seven Canadian provinces from 2009 to 2019 through the Lyme Disease Enhanced Surveillance System are described herein by demographic, geography, time and season. The proportion of males was greater than females. Bimodal peaks in incidence were observed in children and older adults (≥60 years of age) for all clinical signs except cardiac manifestations, which were more evenly distributed across age groups. Proportions of disease stages varied between provinces: Atlantic provinces reported mainly early Lyme disease, while Ontario reported equal proportions of early and late-stage Lyme disease. Early Lyme disease cases were mainly reported between May through November, whereas late Lyme disease were reported in December through April. Increased awareness over time may have contributed to a decrease in the proportion of cases reporting late disseminated Lyme disease. These analyses help better describe clinical features of reported Lyme disease cases in Canada. [ABSTRACT FROM AUTHOR]

Elementary physical and health education (PHE) teachers play key roles in establishing inclusive learning environments. However, how they attend to inclusive pedagogy are not fully highlighted in the research literature. This study examined how elementary PHE teachers understand their roles in inclusion and how they attend to day-to-day inclusive pedagogy. Overall, 11 elementary PHE teachers from a province in Eastern Canada were invited to participate in an exploratory qualitative research study. Data were collected through one-on-one interviews and analysed thematically. Participants highlighted four areas where they attend day-to-day to enhance inclusiveness in their teaching: (1) plan universally from the beginning; (2) share ownership with students by providing students with leadership roles, responsibilities, and choices in learning; (3) create positive relationships and partnerships with students and co-educators; and (4) be responsive and reflexive in teaching. This study highlighted the experiences and insights of Canadian elementary PHE teachers in pursuing and enacting inclusive pedagogy. The findings will provide other in-service and pre-service elementary PHE teachers with pragmatic ideas of ensuring and/or strengthening inclusive PHE. The acquired empirical knowledge may also inform teachers in other disciplines, as well as school administrators, policy-makers, and stakeholders when developing/implementing future policies and actions concerning inclusion.

Simple Summary: The whitemarked tussock moth is a pest of balsam fir in the Maritime provinces of Canada, and also poses a threat to human health because the hairs on the larvae are urticating (i.e., they irritate the skin). In this manuscript, we improve a known lure, based on the pheromone of this insect, with the aim to use it as a widespread monitoring/detection method. Because the female-produced sex pheromone of this moth is unstable, lures containing this pheromone only last a day or two in the field; however, our detection method takes advantage of a synthetic propheromone, or pheromone precursor, that is converted to the pheromone by acid within the lure and releases it over time, circumventing the problem of its instability. We found that our lure formulation and pheromone delivery method is more effective as a lure for whitemarked tussock moth than the control treatments in our field study. The whitemarked tussock moth (WMTM), Orgyia leucostigma (J.E. Smith) (Lepidoptera: Erebidae), is an economic pest in Nova Scotia, Canada, where it undergoes periodic outbreaks defoliating several tree species of economic value, including balsam fir, Abies balsamea (L.) Miller (Pinaceae). Herein is described a releasing device for the WMTM sex pheromone (Z,Z)-6, 9-heneicosadien-11-one based on a rubber septum, which converts pheromone precursors, such as acetals, namely (Z,Z)-11,11-dimethoxy-6,9-heneicosadiene and (Z,Z)-6,9-heneicosadien-11-one ethylene ketal, to the pheromone itself by the action of acetic acid and releases it over time. The pheromone is unstable in nature and, consequently, lures made with this compound will only attract WMTM for a day or two. The two pheromone precursors, however, are more stable, and are converted slowly into the pheromone by acetic acid impregnated in the releasing device, or by acidic conditions in the environment. The two pheromone precursors were synthesized in 2019 using a modified, previously published approach. Field trapping studies conducted from 2019–22 showed that traps baited with rubber septa loaded with either (Z,Z)-11,11-dimethoxy-6,9-heneicosadiene by itself or (Z,Z)-6,9-heneicosadien-11-one ethylene ketal plus acetic acid consistently caught significantly more WMTM than traps baited with blank septa in most experiments.

Background: Comprehensiveness of primary care has been declining, and much of the blame has been placed on early-career family physicians and their practice choices. To better understand early-career family physicians' practice choices in Canada, we sought to identify the factors that most influence their decisions about how to practice. Methods: We conducted a qualitative study using framework analysis. Family physicians in their first 10 years of practice were recruited from three Canadian provinces: British Columbia, Ontario, and Nova Scotia. Interview data were coded inductively and then charted onto a matrix in which each participant's data were summarized by code. Results: Of the 63 participants that were interviewed, 24 worked solely in community-based practice, 7 worked solely in focused practice, and 32 worked in both settings. We identified four practice characteristics that were influenced (scope of practice, practice type and model, location of practice, and practice schedule and work volume) and three categories of influential factors (training, professional, and personal). Conclusions: This study demonstrates the complex set of factors that influence practice choices by early-career physicians, some of which may be modifiable by policymakers (e.g., policies and regulations) while others are less so (e.g., family responsibilities). Participants described individual influences from family considerations to payment models to meeting community needs. These findings have implications for both educators and policymakers who seek to support and expand comprehensive care. [ABSTRACT FROM AUTHOR]

Streptococcus pneumoniae serotype 19A is a highly diverse, often antimicrobial-resistant Gram-positive bacterium which can cause invasive pneumococcal disease (IPD). In 2021, public health authorities in the Canadian province of Québec observed an increase of serotype 19A IPD in children <5 years. The purpose of this study was to determine the clonal composition of serotype 19A isolates collected from this age group in Québec, from 2016 to 2021. Forty-one and 37 IPD isolates from children <5 years from Québec and the remainder of Canada, respectively, were sequenced using the Illumina NextSeq platform. Phylogenetic analysis using SNVPhyl identified three clusters, corresponding to three common clones of serotype 19A: CC199, CC320 and ST695. CC199, predominantly represented by ST416, accounted for similar proportions of serotype 19A isolates collected from children in Québec (19.5 %) and other Canadian jurisdictions (OCJs, 21.6 %), with significant presence of ermB (62.5 % and 60 % of ST416 isolates, respectively). CC320 was more commonly identified from OCJs in comparison to Québec (18.9 % vs. 7.3 %, respectively), but were highly antimicrobial-resistant regardless of region. ST695 was the most common clone of serotype 19A collected in Québec from children <5 years, representing 65.9 % of isolates collected over the study period (40.5 % of isolates collected in OCJs). Phylogenetic analysis identified geographical differences in ST695 across Canada; including a large clade specific to Québec (with both susceptible and macrolide-resistant [ ermB ] subclades), and a separate macrolide-resistant (mefA) clade associated with OCJs. The Québec-specific ermB -ST695 clone represented 48.1 % of ST695 collected from the province. Continued genomic surveillance of S. pneumoniae serotype 19A is required to: i) track the prevalence and clonal composition of serotype 19A in Québec in future years; ii) characterize the clonal distribution of serotype 19A in adult populations; and iii) monitor whether the currently geographically restricted ermB -ST695 clone observed in Québec expands to OCJs.

• The COVID-19 pandemic has challenged traditional vaccine guidance infrastructure. • NACI made many strategic adaptations to facilitate timely vaccine advice in Canada. • The pandemic highlighted critical roles for NITAGs in vaccine program design. • Learning from COVID-19 pandemic adaptations, we see a roadmap for future pandemics. The COVID-19 pandemic has challenged traditional vaccine guidance infrastructure and frameworks, and added urgency and complexity to the operation of National Immunization Technical Advisory Groups (NITAGs). Canada's National Advisory Committee on Immunization (NACI) provides immunization guidance to the Public Health Agency of Canada (PHAC) who publicly shares expert and evidence-informed guidance with Canadian provinces and territories. Throughout the pandemic, NACI and PHAC implemented many adaptations to meet urgent needs for pandemic vaccine guidance. In this paper, we describe: structural adaptations in response to the accelerated pace and amount of work required to issue recommendations that were timed around product authorizations and dynamic epidemiology; technical adaptations in response to rapidly evolving evidence of variable quality which required close monitoring, and which promoted reliance on basic vaccine principles due to incomplete direct evidence; the need to provide nimble advice (e.g., off-label recommendations, preferential recommendations); communications adaptations (e.g. identify sustainable spokespeople for the committee, receive stakeholder feedback, and ensure urgent nuanced advice was communicated to a diverse audience); and research adaptations focussing on solutions to constrained supply (e.g. prioritisation, extended intervals, and heterologous schedules). The early pandemic vaccine experience has created a roadmap of lessons and adaptations that should be leveraged in future pandemic vaccine programs, and has highlighted the essential role of NITAGs to complement regulatory structures during pandemics to ensure timely, impactful, and evidence-informed public health vaccine guidance.

The selective use of potato crop models is a key factor in increasing potato production. This requires a better understanding of the synergies and trade-off of crop management while accounting for the controlling effects of potato genetic and agro-climatic factors. Over the years, crop modeling for potato has relied on historical data and traditional management approaches. Improved modeling techniques have recently been exploited to target specific yield goals based on historical climatic records, future climate uncertainties and weather forecasts. However, climate change and new sources of information motivate better modeling strategies that might take advantage of the vast sources of information in the spectrum of actual, optimal and potential yield and potato management methodologies in a more systematic way. In this connection, two questions warrant interest: (i) how to deal with the variability of crop models relevant to their structure, data requirement and crop-soil-environmental factors, (ii) how to provide robustness to the selection process of a model for specific applications under unexpected change of their structure, data requirement and climatic factors. In this review, the different stages of potato model development are described. Thirty-three crop growth models are reviewed and their usage and characteristics are summarized. An overview of the literature is given, and a specific example is worked out for illustration purposes to identity key models suitable for potato management in the Atlantic provinces of Canada. Based on a categorical principal component analysis (CatPCA) procedure three potato models representing three principal components (PCs) were identified which will be useful for future potato production and yield simulation in this geographic area.

Despite the greater visibility of sexual and gender minorities, due to data limitations, the quantitative literature on their citizenship outcomes is very limited. Using a large original survey of Canadian sexual and gender minorities and the Canadian General Social Survey, this article first examines the extent of political inclusion of sexual and gender minorities, as measured by sense of belonging to Canada and the province of residence, likelihood of voting, and confidence in the police and the justice system. Sexual and gender minorities are generally found to have a markedly weaker sense of belonging to Canada and confidence in its institutions. Next, these patterns are re‐examined accounting for the degree of outness. The results indicate considerable discrepancies across sexual and gender minorities in how outness affects their citizenship outcomes. In particular, it seems that the sociopolitical profile of these groups plays an important mediating role in the effects of outness on their citizenship outcomes.

The object of this paper is to investigate the dynamic causal relationship between economic growth and renewable energy in Canada. The causal relationship is examined under the neoclassical production function framework. We employed a panel autoregressive distributed lag model controlling for different states of the economy by incorporating a dummy variable, which indicates the economic peak and trough. The data set consists of annual real GDP, capital formation, labor, and electricity generation by renewables for nine Canadian provinces covering from 1981 to 2015. The empirical results find that there is a unidirectional causality from renewable energy to economic growth in the long run. In the short run, a unidirectional causality going from renewable energy to economic growth only during the expansion period is observed. Our study suggests that renewable energy policies should be designed and implemented in a way that takes into account the nonlinear relationship between renewable energy and economic growth. This could involve promoting the development and deployment of renewable energy sources as part of their economic stimulus packages during economic upturns. [ABSTRACT FROM AUTHOR]

Unlike other high-income countries, Canada has no national policy for drugs treating rare diseases (orphan drugs). Nevertheless, in 2022, the Canadian government committed to creating a national strategy to make access to these drugs more consistent. Our aim was to study whether recommendations made by the Canadian Agency for Drugs and Technology in Health (CADTH) translated into coverage decisions for orphan drugs in Ontario, the largest Canadian province. This study is the first to look at this question for orphan drugs, which are at the center of policy attention. We included 155 orphan drug-indication pairs approved and marketed in Canada between October 2002 and April 2022. Cohen's kappa was used to test the agreement across health technology assessment (HTA) recommendations and coverage decisions in Ontario. Logistic regression was used to test which factors, relevant to decision-makers, might be associated with funding in Ontario. We found only fair agreement between CADTH's recommendations and coverage decisions in Ontario. Although a positive and statistically significant association between favorable HTA recommendations and coverage was found, more than half of the drugs with a negative HTA recommendation were available in Ontario, predominately through specialized funds. Successful pan-Canadian pricing negotiations were a strong predictor of coverage in Ontario. Despite efforts to harmonize access to drugs across Canada, considerable room for improvement remains. Introducing a national strategy for orphan drugs could help increase transparency, consistency, promote collaborations, and make access to orphan drugs a national priority. • Recommendations by the Canadian Agency for Drugs and Technology in Health do not always translate to provincial coverage decisions for new drugs. • We explored whether Canadian Agency for Drugs and Technology in Health's recommendations are aligned with coverage decisions for orphan drugs in Ontario. • Negative health technology assessment recommendations did not necessarily translate to no pan-Canadian pricing negotiations. • More than half the drugs with negative health technology assessment recommendations were available in Ontario through specialized funds. • A national strategy for orphan drugs could prioritize access to these treatments at a national level and harmonize access, at least to some extent, across Canada.

This study estimates international and provincial migrants' impact on provincial-level trade using panel data from 1981 to 2016 for Canadian provinces. The estimated results show that migration plays a significant role in determining Canadian provincial-level trade. Although the stock of provincial migrants is smaller than the stock of immigrants in Canadian provinces, the former plays a consistently positive and significant role in provincial-level trade, while the latter is not consistently significant across estimators. This study reaffirms that labour mobility between Canadian provinces helps reduce provincial trade barriers and promote economic development within Canada. Our results are robust to different estimation methods, model specifications, and alternative measures of migrants' stock in Canadian provinces. [ABSTRACT FROM AUTHOR]

The ethic of care is a moral philosophy that has been used to describe and guide the work of educators, especially those working with students with special education needs (SEN). In this study, 36 principals and vice principals from four provinces in Canada were interviewed about their work with students with SEN during the pandemic. Responses were analyzed using the ethic of care framework. Accordingly, responses indicated that principals were particularly aware of, and responsive towards, the wide range of need experienced by students, their families, and school staff. Principals appeared especially concerned about the social needs of their students with SEN, the emotional support needs of the students' families, and the teachers' distress at not being able to meet all the educational needs of their students. Although most principals described the emotional toll of their work during the pandemic, none identified efforts directed towards self-care. This paper considers these findings in regard to motivational displacement as it relates to an ethic of care and calls for a broader consideration of need within education, such that support is extended to students, school staff and school leaders as the most effective means to foster healthy, future-ready schools. Key words: pandemic, principal, inclusive education, ethic of care, mental health. [ABSTRACT FROM AUTHOR]

This study presents typical values of electrical resistivity for common saturated and unsaturated sediments in Québec in the form of a resistivity chart. The database for this study consists of surface geophysical investigations [i.e., transient electromagnetic (TEM) surveys] together with stratigraphic and hydrogeological data from boreholes drilled among five regions of the Province of Québec in Canada: Mauricie, Abitibi-Témiscamingue, Saguenay-Lac-Saint-Jean, Charlevoix and Haute-Côte-Nord. TEM stations were selected near the sites where boreholes, stratigraphic cross-sections and piezometric surveys were acquired to derive an empirical and local petrophysical relationship and establish a resistivity chart of the sediments. This chart proposes ranges of resistivity applying to fourteen classes of common sediments, seven of which have never been included in previous studies: silty clay, clay with sand/gravel/pebbles, unsaturated clayey silt with sand, saturated and unsaturated silty sand and saturated and unsaturated clayey sand and gravel. A standardization method was developed and used in this study to produce an accurate and representative chart, and to eliminate outliers that might distort the results and reduce their relevance. This method was designed with the aim of mitigating the impact of outliers and ensuring a reliable and consistent dataset. The findings from this study may provide scientists and practitioners with precise electrical resistivity characteristics of typical saturated and unsaturated sediments, enabling a more accurate assessment of groundwater resources.

The enactment of COVID-19 policies in Canada falls under provincial jurisdiction. This study exploits time-series variation across four Canadian provinces to evaluate the effects of stricter COVID-19 policies on daily case counts. Employing data from this time-period allows an evaluation of the efficacy of policies independent of vaccine impacts. While both OLS and IV results offer evidence that more stringent Non-Pharmaceutical Interventions (NPIs) can reduce daily case counts within a short time-period, IV estimates are larger in magnitude. Hence, studies that fail to control for simultaneity bias might produce confounded estimates of the efficacy of NPIs. However, IV estimates should be treated as correlations given the possibility of other unobserved determinants of COVID-19 spread and mismeasurement of daily cases. With respect to specific policies, mandatory mask usage in indoor spaces and restrictions on business operations are significantly associated with lower daily cases. We also test the efficacy of different forecasting models. Our results suggest that Gradient Boosted Regression Trees (GBRT) and Seasonal Autoregressive-Integrated Moving Average (SARIMA) models produce more accurate short-run forecasts relative to Vector Auto Regressive (VAR), and Susceptible–Infected–Removed (SIR) epidemiology models. Forecasts from SIR models are also inferior to results from basic OLS regressions. However, predictions from models that are unable to correct for endogeneity bias should be treated with caution.

The main purpose of the article is to ensure the safety and security development of the country through the effective implementation of its law functions. For this, the main scientific task is to model the correct execution of criminal law functions in the context of safety and security development (provinces and territories of Canada). The object of the study is the system for ensuring safety and security development. The research methodology involves the use of modern modeling methods. IDEF, SMART, and SWOT methods are used. As a result, we received an information diagram of the performance of criminal law functions in the context of safety and security development. The elements of the novelty of the results of the study are presented by presenting the main stages of the implementation of criminal law functions in the context of safety and security development. The information diagram consists of several blocks that, through arrows, allow you to explain key processes. The innovativeness of the article is presented in the form of a model for the implementation of criminal law functions in the context of safety and security development. The study is limited by taking into account only criminal law functions. One of the limitations is not only the functions, but also the narrowing to the criminal law of only one country, and, as a result, the specifics of the law of other countries are not taken into account. Prospects for further research should be devoted to aspects of ensuring legal security in the framework of safety and security development planning. [ABSTRACT FROM AUTHOR]

The objective of this literature review was to compile research findings on climate change and its impacts on crop production in Prairie Provinces of Canada. Our search strategy included finding primary literature articles from various databases. Seven articles reported increases in average and minimum air temperature over time in the Prairie Provinces of Canada. Increases in maximum air temperature were smaller than that forminimum air temperature. Growing degree days and corn heat units also increased over time, which has allowed for potential expansion of corn growth northwards. While overall increases in average annual precipitation and growing season precipitation have occurred in Canada between 1900 and 2021, western Canada showed increases in some regions but decreases in others. Off-season precipitation and snow cover duration in Canada have decreased since 1950. The number of frost-free days has increased across Canada, on the Prairies and southern Saskatchewan since 1900. Annual snowfall has decreased since 1950 and across Canada the annual maximum snow depth has also decreased. Overall, studies focusing on the Prairie Provinces in Canada have shown accelerated changes in several climate parameters over time, affecting cropping areas and crop yields. [ABSTRACT FROM AUTHOR]

This literature review explores the integration experiences of francophone newcomer students in anglophone provinces in Canada. It outlines scholarly findings regarding factors that impact the integration of newcomer students into French public-school systems in predominantly English provinces. We identified two themes related to the integration of francophone newcomer students, including (1) school integration experiences, and (2) out-of-school integration experiences. With respect to school integration, three sub-themes were developed: (a) educational and cultural gaps, (b) language diversity, plurilingualism, and identity, and (c) multiple marginalization of newcomers. Some of the factors that were found to affect integration include: differences between pre- and post-immigration educational contexts, English language proficiency, and (mis)recognition of the diversity within the francophone population. Following the review, gaps in the literature are identified, avenues for future research are proposed, and implications for school psychology are discussed. [ABSTRACT FROM AUTHOR]

This qualitative study highlights parents' perspectives on pandemic-related changes to health promotion programming. We conducted 60-minute, semi-structured telephone interviews with 15 parents (all mothers) of children in Grades 4 to 6 between December 2020 and February 2021 in two western Canadian provinces. Transcripts were analyzed through thematic analysis. While some parents found the health promotion materials helpful, most were overwhelmed and did not access the materials, finding them intrusive, being preoccupied with other things and facing their own personal stressors. This study highlights key factors to be addressed and further investigated to ensure the successful delivery of health promotion programming during future crises. [ABSTRACT FROM AUTHOR]

Natural gas is believed to be a critical transitional energy source. However, natural gas pipelines, once failed, will contribute to a large amount of greenhouse gas (GHG) emissions, including methane from uncontrolled natural gas venting and carbon dioxide from flared natural gas. However, the GHG emissions caused by pipeline incidents are not included in the regular inventories, making the counted GHG amount deviate from the reality. This study, for the first time, establishes an inventory framework for GHG emissions including all natural gas pipeline incidents in the two of the largest gas producers and consumers in North America (United States and Canada) from 1980s to 2021. The inventory comprises GHG emissions resulting from gathering and transmission pipeline incidents in a total of 24 states or regions in the United States between 1970 and 2021, local distribution pipeline incidents in 22 states or regions between 1970 and 2021, as well as natural gas pipeline incidents in a total of 7 provinces or regions in Canada between 1979 and 2021. These datasets can improve the accuracy of regular emission inventories by covering more emission sources in the United States and Canada and provide essential information for climate-oriented pipeline integrity management.

Background: Electroconvulsive therapy (ECT) is a procedural treatment that is potentially life-saving for some patients with severe psychiatric illness. At the start of the global coronavirus disease 2019 (COVID-19) pandemic, ECT practice was remarkably disrupted, putting vulnerable individuals at increased risk of symptom exacerbation and death by suicide. This study aimed to capture the self-reported experiences of psychiatrists based at healthcare facilities across Canadian provinces who were delivering ECT treatments during the first phase of the COVID-19 pandemic (i.e., from mid-March 2020 to mid-May 2020). Methods: A multidisciplinary team of experts developed a survey focusing on five domains: ECT unit operations, decision-making, hospital resources, ECT procedure, and mitigating patient impact. Responses were collected from psychiatrists providing ECT at 67 ECT centres in Canada, grouped by four geographical regions (Ontario, Quebec, Atlantic Canada, and Western Canada). Results: Clinical operations of ECT programs were disrupted across all four regions – however, centres in Atlantic Canada were able to best preserve outpatient and maintenance care, while centres in Western Canada were able to best preserve inpatient and acute care. Similarly, Atlantic and Western Canada demonstrated the best decision-making practices of involving the ECT team and clinical ethicists in the development of pandemic-related guidelines. Across all four regions, ECT practice was affected by the redeployment of professionals, the shortage of personal protective equipment, and the need to enforce social distancing. Attempts to introduce modifications to the ECT delivery room and minimize bag-valve-mask ventilation were consistently reported. All four regions developed a new patient prioritization framework, and Western Canada, notably, aimed to provide ECT to only the most severe cases. Conclusions: The results suggest that ECT provision was disproportionately affected across different parts of Canada. Possible factors that could explain these interregional differences include population, distribution of urban vs. rural areas, pre-pandemic barriers in access to ECT, number of cases, ability to control the spread of infection, and the general reduction in physicians' activities across different areas of health care. Studying these factors in the future will inform how medical centres should respond to public health emergencies and pandemic-related circumstances in the context of procedural treatments.

In 2021, the ten provinces in Canada enacted COVID-19 vaccine mandates that restricted access to non-essential businesses and services to those that could provide proof of full vaccination to decrease the risk of transmission and provide an incentive for vaccination. This analysis aims to examine the effects of vaccine mandate announcements on vaccine uptake over time by age group and province. Aggregated data from the Canadian COVID-19 Vaccination Coverage Surveillance System (CCVCSS) were used to measure vaccine uptake (defined as the weekly proportion of individuals who received at least one dose) among those 12 years and older following the announcement of vaccination requirements. We performed an interrupted time series analysis using a quasi-binomial autoregressive model adjusted for the weekly number of new COVID-19 cases, hospitalizations, and deaths to model the effect of mandate announcements on vaccine uptake. Additionally, counterfactuals were produced for each province and age group to estimate vaccine uptake without mandate implementation. The times series models demonstrated significant increases in vaccine uptake following mandate announcement in BC, AB, SK, MB, NS, and NL. No trends in the effect of mandate announcements were observed by age group. In AB and SK, counterfactual analysis showed that announcement were followed by 8 % and 7 % (310,890 and 71,711 people, respectively) increases in vaccination coverage over the following 10 weeks. In MB, NS, and NL, there was at least a 5 % (63,936, 44,054, and 29,814 people, respectively) increase in coverage. Lastly, BC announcements were followed by a 4 % (203,300 people) increase in coverage. Vaccine mandate announcements could have increased vaccine uptake. However, it is difficult to interpret this effect within the larger epidemiological context. Effectiveness of the mandates can be affected by pre-existing levels of uptake, hesitancy, timing of announcements and local COVID-19 activity. [ABSTRACT FROM AUTHOR]

Background: Case management is one of the most frequently performed interventions to mitigate the negative effects of high healthcare use on patients, primary care providers and the healthcare system. Reviews have addressed factors influencing case management interventions (CMI) implementation and reported common themes related to the case manager role and activities, collaboration with other primary care providers, CMI training and relationships with the patients. However, the heterogeneity of the settings in which CMI have been implemented may impair the transferability of the findings. Moreover, the underlying factors influencing the first steps of CMI implementation need to be further assessed. This study aimed to evaluate facilitators and barriers of the first implementation steps of a CMI by primary care nurses for people with complex care needs who frequently use healthcare services. Methods: A qualitative multiple case study was conducted including six primary care clinics across four provinces in Canada. In-depth interviews and focus groups with nurse case managers, health services managers, and other primary care providers were conducted. Field notes also formed part of the data. A mixed thematic analysis, deductive and inductive, was carried out. Results: Leadership of the primary care providers and managers facilitated the first steps of the of CMI implementation, as did the experience and skills of the nurse case managers and capacity development within the teams. The time required to establish CMI was a barrier at the beginning of the CMI implementation. Most nurse case managers expressed apprehension about developing an "individualized services plan" with multiple health professionals and the patient. Clinic team meetings and a nurse case managers community of practice created opportunities to address primary care providers' concerns. Participants generally perceived the CMI as a comprehensive, adaptable, and organized approach to care, providing more resources and support for patients and better coordination in primary care. Conclusion: Results of this study will be useful for decision makers, care providers, patients and researchers who are considering the implementation of CMI in primary care. Providing knowledge about first steps of CMI implementation will also help inform policies and best practices. [ABSTRACT FROM AUTHOR]

The implementation of school reforms to advance reconciliation with Indigenous peoples provides an opportunity to explore what Canadians think is important in framing their identities and values. This paper draws on data from a survey of public perspectives on education for reconciliation activities in two Canadian provinces, Alberta and Saskatchewan. We consider the broader community context within which schools are located. By examining public perspectives, we are able to assess how curricular initiatives related to reconciliation are understood by community members, both as a priority in itself and in relation to other key curricular areas. Informed by critical race theory, our findings suggest that reconciliation is restricted to activities that do not involve extensive change to existing curricular and ideational frameworks. These perspectives exist alongside extensive opposition to reconciliation justified by claims that Indigenous experiences and perspectives are receiving undue attention relative to more pressing educational priorities. Our findings suggest that aims to transform dominant understandings about Canadian history and identity remain far from being fulfilled. [ABSTRACT FROM AUTHOR]

Background The Brain Tumor Registry of Canada was established in 2016 to enhance infrastructure for surveillance and clinical research on Central Nervous System (CNS) tumors. We present information on primary CNS tumors diagnosed among residents of Canada from 2010 to 2015. Methods Data from 4 provincial cancer registries were analyzed representing approximately 67% of the Canadian population. Age-standardized incidence rates (ASIR) and 95% confidence intervals (CI) were calculated using the 2011 Canadian population age distribution. Net survival was estimated using the Pohar-Perme method. Results A total of 31 644 primary tumors were identified for an ASIR of 22.8 per 100 000 person-years. Nonmalignant tumors made up 47.1% of all classified tumors, with mixed behaviors present in over half of histology groupings. Unclassified were 19.5% of all tumors. The most common histological subtypes are meningiomas (ASIR = 5.5 per 100 000 person-years); followed by glioblastomas (ASIR 4.0 per 100 000 person-years). The overall 5-year net survival rate for CNS tumors was 65.5%; females 70.2% and males 60.4%. GBMs continue to be the most lethal CNS tumors for all sex and age groups. Conclusions The low annual frequency of most CNS tumor subtypes emphasizes the value of population-based data on all primary CNS tumors diagnosed among Canadians. The large number of histological categories including mixed behaviors and the proportion of unclassified tumors emphasizes the need for complete reporting. Variation in incidence and survival across histological groups by sex and age highlights the need for comprehensive and histology-specific reporting. These data can be used to better inform research and health system planning. [ABSTRACT FROM AUTHOR]

Earth's continental crust has evolved through a series of supercontinent cycles, resulting in a patchwork of Archean cores surrounded by terranes, fragments, and slivers of younger crustal additions. However, the dispersal (and/or stranding) of continental fragments during breakup is not well understood. Inherited structures from previous tectonic activity may explain the generation of continental terranes by controlling first-order deformation during rifting. Here, we explored the influence of lithospheric deformation related to ancient orogenesis, focusing on the impact of the Torngat orogen in the genesis of the Nain Province continental fragment in Eastern Canada. We present three-dimensional continental extension models in the presence of an inherited lithospheric structure and show that a narrow continental terrane could be separated and stranded by deep lithospheric scarring. The results show that continental terranes formed by this method would be limited to a width of 100-150 km, imposed by tectonic conditions during continental suturing. The findings have broad implications, demonstrating an original theory on the fundamental geologic problem of terrane generation and continent breakup. [ABSTRACT FROM AUTHOR]
