The article comments on the pledge of Prime Minister Paul Martin, to find funds for urban renewal and to improve the lot of Canada's increasingly restive urban-dwellers. Mr Martin himself deserves a share of the blame for the cities' problems. As finance minister for nearly nine years, Mr Martin chopped billions from federal transfers to the provinces to help eliminate budget deficits. The provinces offloaded responsibility for a range of social services to local municipalities, and cut their own cash transfers. Among federal states that the OECD monitors, the upper levels of government in Canada give least to their cities. Meanwhile, in population terms, Canadian cities have boomed. A century ago, 80% of the population was rural; today 80% of the country's 31m people live in towns and cities, and half are concentrated in five city-regions. The cities, however, are revolting. The amalgamation of a dozen or so municipalities into mega-cities--undertaken by the provinces to cut their own costs--has helped to produce a new crop of mayors with big ideas and new influence. The election, in November, of David Miller as Toronto's reforming mayor gave extra strength to a coalition of uppity civic leaders. Glen Murray, mayor of Winnipeg, has called for a new deal to allow "tax shifting", along Scandinavian lines. The new prime minister has hinted that he would allocate half the revenues from a federal fuel tax, worth C$2.5 billion ($1.9 billion) a year, directly to the cities. He has appointed John Godfrey, a well-regarded Ontario MP, as his urban adviser, and persuaded Mike Harcourt, a former premier of British Columbia and once mayor of Vancouver, to chair a high-powered advisory committee on urban issues.
