Canada is the largest country in the world by total area.

Discover Canada records this in one direct sentence about Canada's size. The guide writes: Canada is the second largest country on earth—10 million square kilometres. The status the test wants is therefore false — Canada is the second largest, not the largest.

Two precise commitments. Discover Canada commits Canada's geographic size to TWO specific facts: (1) Canada is the second largest country on earth, and (2) Canada's area is 10 million square kilometres. So the source is unambiguous on both ranking and absolute size. Canada is not the largest country — that distinction belongs to another country (Russia, by reference outside the source) — but Canada's 10-million-square-kilometre area still makes it the second-largest country on earth, dwarfing all but one other nation.

Canada's vast size is bordered by three oceans. Discover Canada commits Canada's frontiers to THREE specific oceans: "Three oceans line Canada's frontiers: the Pacific Ocean in the west, the Atlantic Ocean in the east, and the Arctic Ocean to the north." So the second-largest-country status is reflected in Canada's three-ocean coastline — east, west, and north — making Canada one of only a handful of countries with frontage on three oceans. Along the southern edge lies the Canada-United States boundary, the world's longest unfortified border.

Canada's area divides into five regions. Discover Canada commits Canada's geography to "five distinct regions": the Atlantic Provinces, Central Canada, the Prairie Provinces, the West Coast, and the Northern Territories. So the 10-million-square-kilometre area is organised into five named regions — each with its own provinces or territories, climate, and culture. Canada includes many different geographical areas, from the Atlantic shores to the Pacific Ocean to the Arctic Circle. The second-largest-country status reflects this enormous range — vast forests, prairies, mountains, tundra, and three coastlines. So when the test asks whether Canada is the largest country in the world by total area, the source-precise answer is false. Canada is the second largest — a remarkable size in absolute terms, but not the largest.

The question is testing whether new citizens know Canada's global size ranking. Discover Canada commits to one ranking: second largest country on earth. So the statement that Canada is the largest country is false.

The wrong answer ("True") reverses the source — Canada is the second largest, not the largest. The named ranking is exact, paired with the absolute area of 10 million square kilometres. Only the false answer matches the source.
