Canada ranks 37th by population among countries of the world, comprising about 0.5% of the world's total, with about 41.5 million Canadians as of 2025. Despite being the second-largest country by total area (fourth-largest by land area), the vast majority of the country is sparsely inhabited, with most of its population south of the 55th parallel north. Just over 60 percent of Canadians live in just two provinces: Ontario and Quebec. Though Canada's overall population density is low, many regions in the south, such as the Quebec City–Windsor Corridor, have population densities higher than several European countries. Canada has six population centres with more than one million people: Toronto, Montreal, Vancouver, Calgary, Edmonton and Ottawa.
The large size of Canada's north, which is currently not arable, and thus cannot support large human populations, significantly lowers the country's carrying capacity. In 2021, the population density of Canada was 4.2 people per square kilometre.
