The largest city in Canada is Toronto, with roughly 2.8 million residents within its city limits, followed by Montreal (1.8 million), Calgary (1.3 million), Ottawa and Edmonton (about 1.0 million each), Winnipeg (0.75 million), Mississauga (0.72 million), Vancouver (0.66 million), Brampton (0.66 million), and Hamilton (0.57 million). Together these ten cities anchor a country of around 38 million people, one of the most heavily urbanised nations on Earth despite its vast, sparsely populated interior.
It is worth noting that these figures count people living inside official municipal boundaries. Metropolitan area populations are far larger — Greater Toronto, for example, is home to more than 6 million people, while the Vancouver and Montreal metro regions each exceed 2.5 million.
The Ten Largest Canadian Cities
- Toronto (Ontario) — ~2.8 million: Canada's financial capital and most populous city, home to the Toronto Stock Exchange and the CN Tower.
- Montreal (Quebec) — ~1.8 million: The largest French-speaking city in the Americas and a centre of culture and aerospace.
- Calgary (Alberta) — ~1.3 million: The hub of Canada's oil and gas industry, set near the Rocky Mountains.
- Ottawa (Ontario) — ~1.0 million: The national capital, seat of Parliament and federal government.
- Edmonton (Alberta) — ~1.0 million: Alberta's capital and a major energy and logistics centre.
- Winnipeg (Manitoba) — ~0.75 million: The largest city on the Prairies and a longtime transport crossroads.
- Mississauga (Ontario) — ~0.72 million: A fast-growing city in the Greater Toronto Area, home to Pearson Airport.
- Vancouver (British Columbia) — ~0.66 million: Canada's main Pacific port and gateway to Asia.
- Brampton (Ontario) — ~0.66 million: One of the country's fastest-growing and most diverse cities.
- Hamilton (Ontario) — ~0.57 million: A steel-producing port city at the western end of Lake Ontario.
Why Ontario Dominates the List
Five of Canada's ten largest cities — Toronto, Ottawa, Mississauga, Brampton, and Hamilton — are in the single province of Ontario. This concentration reflects Ontario's role as the country's industrial and economic heartland and its position along the densely settled corridor between the Great Lakes and the St. Lawrence River. The cities of Toronto, Mississauga, and Brampton, along with neighbouring municipalities, blend into one continuous urban region known as the Golden Horseshoe, which contains roughly a quarter of all Canadians. Ontario's pull comes from its diversified economy spanning finance, manufacturing, technology, and government.
The Urban West and the French-Speaking Centre
Beyond Ontario, the list shows Canada's regional balance. Quebec contributes Montreal, the cultural capital of French Canada, where the everyday language of business and life is French. The province of Alberta supplies two entries — Calgary and Edmonton — both fuelled by the energy sector and among the fastest-growing major cities in the country during boom years. British Columbia is represented by Vancouver, consistently ranked among the world's most liveable cities thanks to its mild climate and mountain-and-sea setting, while Manitoba's Winnipeg holds its place as the dominant city of the central Prairies.
A Highly Urban, Border-Hugging Country
Although Canada is the second-largest country in the world by land area, more than 80 percent of its people live in towns and cities, and the great majority cluster within roughly 150 kilometres of the United States border. This is partly a matter of climate and geography: the far north is cold and remote, so population gathers in the warmer, more accessible south. As a result, a handful of metropolitan regions account for an outsized share of the nation's residents and economic output. You can explore where each of these cities sits on the map in our canada country guide.
How the Cities Have Grown
Canadian cities owe much of their recent growth to immigration. Toronto, Vancouver, and Brampton in particular have become some of the most multicultural places on the planet, with large communities tracing their roots to South Asia, East Asia, the Caribbean, and beyond. Suburban cities such as Mississauga and Brampton expanded rapidly in recent decades as the Greater Toronto Area spread outward. By contrast, older industrial centres like Hamilton and Winnipeg have grown more steadily, while energy-driven Calgary and Edmonton have seen their populations swing with the fortunes of the oil market.
Everyone Lives Near the Border
Canada is the second-largest country in the world and one of the most sparsely populated, and the reason both statements are true is that roughly ninety per cent of Canadians live within about 160 kilometres of the United States border.
Every city in the top ten sits in that strip. The country's habitable band is squeezed between the American border and the Canadian Shield, the vast expanse of ancient rock, lake and boreal forest that covers about half the landmass and supports very little agriculture or settlement.
The densest section is the Quebec City-Windsor corridor along the St Lawrence and the lower Great Lakes, which holds more than half the national population and contains Toronto, Montreal, Ottawa and Quebec City.
Toronto Is Built by Immigration
Toronto is among the most foreign-born large cities in the world, with roughly half its residents born outside Canada, a proportion higher than New York, London or Sydney. More than 150 languages are spoken across the metropolitan area.
That composition is the result of deliberate policy. Canada introduced a points-based immigration system in 1967 which removed the previous national-origin preferences, and per capita intake has remained among the highest of any large economy since.
The city overtook Montreal as Canada's largest during the 1970s, a shift accelerated by the political uncertainty around Quebec sovereignty, which moved a number of corporate head offices and much of the financial sector west along the 401.
Montreal Is the Second-Largest French-Speaking City
Montreal is, after Paris, generally described as the largest French-speaking city in the world. French is the official language of Quebec, protected by the Charter of the French Language of 1977, which governs commercial signage, workplace language and the schooling of immigrant children.
The city sits on an island in the St Lawrence at the foot of the Lachine Rapids, the point above which ships could not pass, which is precisely why a settlement grew there in 1642. The Lachine Canal and later the St Lawrence Seaway removed that obstacle and, in doing so, allowed ocean traffic to bypass the port for the Great Lakes.
Expo 67 and the 1976 Olympics left the city its metro, Habitat 67 and a stadium whose debt was not finally paid off until 2006.
Vancouver, the Mountains and the Price of Housing
Vancouver is hemmed in on every side: ocean to the west, mountains to the north, the American border to the south and the protected Agricultural Land Reserve to the east. There is very little direction left for the city to grow.
The result has been housing costs consistently ranked among the least affordable in the world relative to local incomes, and a policy response including a foreign-buyers tax and an empty-homes tax that other cities have since copied.
The city has the mildest winters of any major Canadian centre, moderated by the Pacific, and it is the only one where snow is unusual rather than assumed. Expo 86 and the 2010 Winter Olympics both accelerated its transformation from a resource port into a service and film-production centre.
The Prairie Cities and the Oil
Calgary and Edmonton are the two large cities of Alberta, and both are tied to petroleum, though differently. Calgary holds the corporate head offices, the engineering firms and the financial services; Edmonton is closer to the oil sands around Fort McMurray and functions as the industrial and supply base.
Their fortunes therefore rise and fall with the oil price in a way no other Canadian cities do, and the population swings between boom and bust years are measurable in migration statistics from the Atlantic provinces.
Winnipeg, further east, was the gateway to the west before the railway extended further and was briefly one of the fastest-growing cities in North America. It sits at the confluence of the Red and Assiniboine rivers, a meeting point used by Indigenous peoples and later the Metis, whose resistance under Louis Riel in 1869 and 1885 shaped the terms on which the prairies entered Confederation.
Common Questions About Canadian Cities
What is the largest city in Canada?
Toronto is the largest city in Canada, with about 2.8 million people inside its municipal boundaries and more than 6 million in its surrounding metropolitan area. It is the country's financial and cultural centre.
Is Ottawa or Toronto the capital of Canada?
Ottawa is the capital of Canada, even though it is smaller than Toronto, Montreal, and Calgary. It was chosen as capital in 1857, partly for its location between English-speaking Ontario and French-speaking Quebec.
Which Canadian province has the most large cities?
Ontario has the most, with five of the country's ten largest cities: Toronto, Ottawa, Mississauga, Brampton, and Hamilton. Many of these form part of the densely populated Golden Horseshoe region.
Is Vancouver bigger than Calgary?
By city population, Calgary (about 1.3 million) is larger than the City of Vancouver (about 0.66 million). However, the Vancouver metropolitan area is comparable in size, as much of its population lives in surrounding municipalities like Surrey and Burnaby.
Why is Ottawa the capital rather than Toronto or Montreal?
Queen Victoria chose it in 1857 as a compromise between the rival claims of Canada West and Canada East. Ottawa sat on the border between them, was defensible at a distance from the American frontier, and satisfied neither faction's preference, which was rather the point.
