What is the capital city of Canada?

The capital city of Canada is Ottawa. Recognized as the political heart of the country, Ottawa is home to important national institutions, including the Parliament of Canada and the official residences of the Prime Minister and the Governor General. This designation makes it a significant cultural and historical center, hosting numerous national museums and events.

In contrast, while Toronto, Vancouver, and Montreal are major Canadian cities known for their economic, cultural, and social contributions, they serve different roles. Toronto is the largest city and a major financial hub; Vancouver is known for its picturesque views and diverse cultural scene; and Montreal is recognized for its bilingual heritage and vibrant arts community, none of which is the capital of the country. Therefore, Ottawa stands out as the correct answer.
