Which city is the largest in Canada by population?

Discover Canada records this in one direct sentence. The guide writes: Toronto is the largest city in Canada and the country's main financial centre. Many people work in the service or manufacturing industries, which produce a large percentage of Canada's exports. The largest Canadian city the test wants is therefore Toronto.

Toronto is doubly significant. Discover Canada ties it to two major roles: largest city and main financial centre. So Toronto's role goes beyond population — it is also where Canada's banking, stock-trading, and corporate-headquarter functions are concentrated. Toronto's business district is described elsewhere in the guide as "Canada's financial capital."

Toronto is in Ontario. Discover Canada identifies Toronto as the capital of Ontario, the most populous province (more than 12 million people, more than one-third of Canadians). So the largest city sits inside the most populous province — making Ontario as a whole the population centre of Canada and Toronto the urban heart of that province.

Other large Canadian cities follow Toronto. Discover Canada names Montreal as "Canada's second largest city and the second largest mainly French-speaking city in the world after Paris," with a population of about eight million in Quebec. Ottawa is described as "Canada's fourth largest metropolitan area." So the population-ranked top cities run: Toronto (largest), then Montreal (second largest), and Ottawa is fourth largest. Vancouver and Calgary are also major Canadian cities. The question's answer — Toronto as the largest — is a foundational geographic fact about urban Canada.

Toronto's economic role is also notable. Discover Canada writes that "many people work in the service or manufacturing industries, which produce a large percentage of Canada's exports." So Toronto sits at the heart of Canada's service-and-manufacturing economy — combining its size with national economic centrality. The Niagara region of Ontario also has the country's vineyards, wines, and fruit crops, and Ontario produces (with Quebec) more than three-quarters of all Canadian manufactured goods.

The question is testing whether new citizens know which Canadian city has the largest population. Discover Canada commits to one city: Toronto. The right test answer matches that.

The wrong answer choices each pick a different major city. Montreal is Canada's second largest city — large but not the largest. Vancouver is on the Pacific coast in British Columbia — major, but not the largest. Ottawa is Canada's fourth largest metropolitan area — important as the national capital but not the largest by population. Only Toronto matches.
