Canada is home to about 41.5 million people as of 2025, ranking 37th in the world by population, or roughly 0.5% of the global total. Despite being the world’s second-largest country by area, most Canadians live in a narrow southern band along the U.S. border. The Quebec City–Windsor Corridor alone accounts for nearly half of the country’s people, while much of the northern territory remains sparsely inhabited.
Indigenous Populations and Early Demographics
Before European contact, estimates of the Indigenous population in what is now Canada ranged between 200,000 and 2 million, with 500,000 being the widely accepted figure. Colonization brought devastating waves of smallpox, measles, and influenza, causing population declines of up to 80% in some communities.
By 1822, the Indigenous population was recorded at about 283,500, but by 1871 — after disease, displacement, and conflict — the count had fallen to just over 102,000. Recovery began in the 20th century, and by 2021 more than 1.8 million Indigenous people identified as First Nations, Métis, or Inuit, comprising 5% of the national population.
Growth Under French and British Rule
The first European census in Canada was conducted in 1666 by Jean Talon, counting just over 3,200 settlers in New France. By 1754, the French colonial population had grown to about 55,000, largely through high birth rates rather than immigration.
After Britain took control in 1763, population growth accelerated. Loyalists fleeing the American Revolution brought around 60,000 settlers north, while Irish migration during the Great Famine of the 1840s further boosted numbers. By Confederation in 1867, Canada’s population stood at about 3.5 million.
Post-Confederation Expansion
Canada’s first national census in 1871 recorded 3.7 million people. The population more than doubled by 1911, reaching 7.2 million, thanks in part to the settlement of the Prairie provinces.
The post-World War II baby boom (1947–1966) was another transformative period, with annual births topping 400,000. By 1971, the population had passed 21.5 million. Immigration continued to supplement growth, especially from Europe in the mid-20th century and from Asia, Africa, and the Middle East in later decades.
Modern Population Trends
Canada’s population reached 36.9 million in the 2021 census, rising to 41.5 million by April 2025. Recent growth has been driven less by natural increase and more by immigration, which accounts for nearly all of Canada’s net population gains.
In 2023, for the first time in history, Canada’s population increased by over one million people in a single year, mainly due to immigration programs addressing labour shortages.
Today, more than 60% of Canadians live in Ontario and Quebec, while six metropolitan areas — Toronto, Montreal, Vancouver, Calgary, Edmonton, and Ottawa — have populations exceeding one million.
Looking Ahead
Projections suggest Canada’s population could reach 47 million by 2036 and over 63 million by 2061 under high-growth scenarios. With its vast territory but limited arable land in the north, Canada’s demographic future will remain shaped by migration policies, urban concentration, and the ongoing growth of Indigenous and multicultural communities.
