Purpose: To investigate why Canadian nutrition care providers choose, or not, to integrate nutritional genomics into practice, and to evaluate the nutritional genomics training/education experiences and needs of nutrition providers in Canada, while comparing those of dietitians to non-dietitians. Methods: A cross-sectional online survey was distributed across Canada from June 2021 to April 2022. Results: In total, 457 healthcare providers (HCPs) [ n  = 371 dietitians (81.2%)] met the inclusion criteria. The majority ( n  = 372; 82.1%) reported having no experience offering nutritional genomics to clients ( n  = 4 did not respond). Of the 81 respondents with experience (17.9%), the most common reason to integrate nutrigenetic testing into practice was the perception that clients would be more motivated to change their eating habits (70.4%), while the most common reason for not integrating such tests was the perception that the nutrigenetic testing process is too complicated ( n  = 313; 84.1%). Dietitians were more likely than non-dietitians to view existing scientific evidence as an important educational topic ( p  = 0.002). The most selected useful educational resource by all HCPs was clinical practice guidelines ( n  = 364; 85.4%). Conclusions: Both dietitians and non-dietitians express a desire for greater nutritional genomics training/education; specific educational needs differ by type of HCP. Low implementation of nutrigenetic testing may be partly attributed to other identified barriers.
