Study Tip
Consider the province with the largest population in Canada. It's also the most populous province, accounting for nearly a third of the country's total population.
What should you know about this topic?
Ontario is Canada's most populous province. Discover Canada states that more than one third of Canadians live in Ontario. Its capital is Toronto, which is also Canada's largest city and a major centre for finance, business and culture. The national capital, Ottawa, is also in Ontario. Ontario, together with Quebec, forms Central Canada, the region where more than half of all Canadians live.
Ontario's large population is linked to its geography and history. The Great Lakes and the St. Lawrence River provided routes for trade and settlement. After the American Revolution, many United Empire Loyalists settled in what is now Ontario. Later, waves of immigrants from many countries came to work in its farms, factories and cities. Today the province is known for manufacturing, services, and a diverse population. The Niagara region is known for growing fruit and making wine, and the Great Lakes help define the province's southern landscape.
Related test questions often ask about the capital cities of each province and territory, the five regions of Canada, and where most French-speaking Canadians live (Quebec). Be careful not to mix up "more than half of Canadians" (Central Canada, meaning Ontario and Quebec together) with "more than one third" (Ontario alone). Remembering these two facts as a pair will help you answer either version of the question. Ontario is also home to many newcomers, who often settle in the Toronto area.
Why are the other answers wrong?
- Quebec: Quebec has the second-largest population and is home to most Francophones, but it does not hold one third of all Canadians.
- Manitoba: Manitoba is a Prairie Province with a much smaller population than Ontario.
- Northwest Territories: The Northwest Territories is a territory, not a province, and has a very small population.
What is the most common mistake?
Learners often pick Quebec because it is large and well known. Quebec is the second most populous province; it is Ontario alone that holds more than one third of Canadians.
How can you remember the answer?
"One in three lives in O": O for Ontario looks like a big circle holding a third of Canada.
