Which cities form the three most populous urban regions in Canada?

• A. Calgary, Edmonton, Ottawa
• B. Halifax, St. John’s, Charlottetown
• C. Toronto, Montreal, Vancouver
• D. Winnipeg, Saskatoon, Regina

Answer: (C)

In Canada, the largest urban regions are measured by metropolitan populations—the city core plus surrounding suburbs that are economically linked. Using this definition, the three biggest census metropolitan areas are Toronto, Montreal, and Vancouver. Toronto is the largest, acting as the country’s main economic and cultural hub; Montreal is the second-largest, a major center for commerce, education, and arts; Vancouver is the third-largest, a key West Coast gateway with strong population and growth. The other groups include cities that, while sizable, do not reach the same metropolitan scale as these three. Hence, Toronto, Montreal, and Vancouver form the three most populous urban regions.
