Which province is the second-largest by area in Canada?

Discover Canada identifies Ontario as one of Canada's two Central Canada provinces — paired with Quebec, which is the largest province by area. By size, Ontario follows Quebec, making Ontario the second-largest province by area. The guide writes: More than half the people in Canada live in cities and towns near the Great Lakes and the St. Lawrence River in southern Quebec and Ontario, known as Central Canada and the industrial and manufacturing heartland.

Ontario is also Canada's most populous province. Discover Canada writes: "At more than 12 million, the people of Ontario make up more than one-third of Canadians. The large and culturally diverse population, natural resources and strategic location contribute to a vital economy. Toronto is the largest city in Canada and the country's main financial centre." So Ontario combines large area with the country's biggest population — making it the demographic, financial, and (after Quebec) geographic giant of Canada.

Ontario reaches from the Great Lakes to Hudson Bay. Discover Canada writes that "there are five Great Lakes located between Ontario and the United States: Lake Ontario, Lake Erie, Lake Huron, Lake Michigan (in the U.S.A.) and Lake Superior, the largest freshwater lake in the world." So Ontario's southern boundary runs along four of the five Great Lakes — Lake Ontario, Lake Erie, Lake Huron, and Lake Superior. The province extends north to Hudson Bay, giving it both Great Lakes coastline and an Arctic-coast presence.

Ontario's economic profile is broad. Discover Canada writes: "Many people work in the service or manufacturing industries, which produce a large percentage of Canada's exports. The Niagara region is known for its vineyards, wines and fruit crops. Ontario farmers raise dairy and beef cattle, poultry, and vegetable and grain crops. Founded by United Empire Loyalists, Ontario also has the largest French-speaking population outside of Quebec, with a proud history of preserving their language and culture." So Ontario combines manufacturing, agriculture, services, and Francophone heritage. Compared with the other provinces, Ontario is second to Quebec by area, but first by population, first by Toronto-led financial concentration, and first by manufacturing share. When the test asks for the second-largest province by area, the answer aligns with Ontario's geographic ranking.

The question is testing whether new citizens know which province is second-largest by area. The province ranked second after Quebec by area is Ontario. The right test answer matches that.

The wrong answer choices each substitute a different province. "British Columbia" is on the Pacific coast and is geographically large but smaller than Ontario by area. "Alberta" is a Prairie province with substantial area but smaller than Ontario. "Manitoba" is the easternmost Prairie province, also smaller in area than Ontario. Only Ontario — second to Quebec — fits as the second-largest by area.
