Which province borders Newfoundland and Labrador?

The province bordering Newfoundland and Labrador is Quebec. Of the four Atlantic Provinces, Newfoundland and Labrador is the only one with a land boundary, and that boundary runs along the Labrador mainland — the part of the province on the continent. The island of Newfoundland is separated from the rest of Canada by water; only Labrador touches another province, and that province is Quebec.

Discover Canada describes Newfoundland and Labrador as a single province with a distinctive geography. The guide writes: Newfoundland and Labrador is the most easterly point in North America and has its own time zone. In addition to its natural beauty, the province has a unique heritage linked to the sea. The province pairs an island (Newfoundland) with a mainland region (Labrador) — and the mainland portion is the part adjacent to Quebec.

Quebec, in contrast, is a Central Canada province. Discover Canada writes that "nearly eight million people live in Quebec, the vast majority along or near the St. Lawrence River." Quebec's geography is dominated by the Canadian Shield in the north and the St. Lawrence valley in the south. Far to the northeast of the populated St. Lawrence corridor, Quebec's land continues all the way up to its boundary with Labrador.

Two source-grounded resource facts strengthen the link. Discover Canada notes that "Labrador also has immense hydro-electric resources," and that Quebec's "huge supply of fresh water has made it Canada's largest producer of hydro-electricity." So both sides of the Quebec–Labrador boundary are major hydro regions — a reminder that they sit on the same Canadian Shield, divided only by a provincial line. The other Atlantic Provinces — Nova Scotia, New Brunswick, and Prince Edward Island — are all to the south and have no shared boundary with Newfoundland and Labrador.

The question is testing whether new citizens know which Canadian province shares a land border with Newfoundland and Labrador. The Labrador mainland touches one province only: Quebec. The right test answer matches that.

The wrong answer choices each pick a different Atlantic Province. New Brunswick, Nova Scotia, and Prince Edward Island are all to the south of the St. Lawrence and Gulf of St. Lawrence. None shares a land boundary with Labrador. The province whose mainland border meets Labrador is Quebec.
