Population of Canada by province and territory

Canada is divided into 10 provinces and three territories. The majority of Canada's population is concentrated in the areas close to the Canada–US border. Its four largest provinces by area (Ontario, Quebec, British Columbia, and Alberta) are also its most populous; together they account for 86.5 percent of the country's population. The territories (the Northwest Territories, Nunavut, and Yukon) account for over a third of Canada's area but are home to only 0.32 percent of its population, which skews the national population density value.

Canada's population grew by 5.24 percent between the 2016 and 2021 censuses.^[1] With the exceptions of Newfoundland and Labrador and the Northwest Territories, all territories and provinces increased in population from 2016 to 2021. In terms of percent change, the fastest-growing province or territory was Yukon with an increase of 12.1 percent between 2016 and 2021, followed by Prince Edward Island with 7.99 percent growth.

Generally, provinces steadily grew in population along with Canada. However, some provinces such as Saskatchewan, Prince Edward Island, and Newfoundland and Labrador experienced long periods of stagnation or population decline. Ontario and Quebec were always the two most populous provinces in Canada, with over 60 percent of the population at any given time. The demographic importance of the West steadily grew over time, while the importance of Atlantic Canada steadily slipped. Canada's population has increased every year since Confederation in 1867: see List of population of Canada by year.
