Canada is surrounded by three oceans: the Pacific, the Atlantic, and the Arctic.

Discover Canada records this in one direct sentence about Canada's frontiers. The guide writes: 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. The status the test wants is therefore true — Canada is bordered by the Pacific, Atlantic, and Arctic oceans.

Three precise commitments. Discover Canada commits Canada's named oceans to THREE specific named bodies and three specific named directions: (1) the Pacific Ocean in the west; (2) the Atlantic Ocean in the east; (3) the Arctic Ocean to the north. So the source pinpoints both the named oceans and their named cardinal positions.

Canada is the second largest country on earth. Discover Canada commits Canada's size to a specific named ranking: "Canada is the second largest country on earth—10 million square kilometres." So Canada's three-ocean coastline is one of the longest in the world — befitting a country of that size. The named southern boundary is also specified: "Along the southern edge of Canada lies the Canada-United States boundary." So Canada has THREE oceans and ONE major land boundary (with the United States).

The five named regions span the three oceans. Discover Canada commits Canada to "five distinct regions": the Atlantic Provinces; Central Canada; the Prairie Provinces; the West Coast; the Northern Territories. So the named geography spans the Atlantic Ocean (Atlantic Provinces); the Great Lakes and St. Lawrence (Central Canada); the Prairie heartland (Prairie Provinces); the Pacific (West Coast); and the Arctic (Northern Territories). The three named oceans give Canada one of the most extensive and geographically diverse coastlines in the world. Both Canada and the U.S.A. are committed to a safe, secure and efficient frontier — meaning the named southern land boundary is well-managed alongside the three named ocean coastlines. So when the test asks whether Canada is surrounded by three oceans (Pacific, Atlantic, and Arctic), the source-precise answer is true.

The question is testing whether new citizens know Canada's three named oceans. Discover Canada commits to one named pairing: Pacific (west), Atlantic (east), and Arctic (north). The right test answer matches that — true.

The wrong answer ("False") reverses the source — Canada IS bordered by three named oceans. The named bodies and their named directions match the test statement exactly. Only the true answer matches the source.
