Quebec is one of the thirteen provinces and territories of Canada. It is bordered to the west by the province of Ontario and the bodies of water James Bay and Hudson Bay; to the north by Hudson Strait and Ungava Bay; to the east by the Gulf of Saint Lawrence and the province of Newfoundland and Labrador; and to the south by the province of New Brunswick and the U.S. states of Maine, New Hampshire, Vermont, and New York. It also shares maritime borders with Nunavut, Prince Edward Island, and Nova Scotia. Quebec is Canada's largest province by area and its second-largest administrative division; only the territory of Nunavut is larger.

Alaska is a U.S. state on the northwest extremity of the country's West Coast, just across the Bering Strait from Asia. An exclave of the U.S., it borders the Canadian province of British Columbia and territory of Yukon to the east and southeast and has a maritime border with Russia's Chukotka Autonomous Okrug to the west. Alaska is by far the largest U.S. state by area, comprising more total area than the next three largest states Texas, California, and Montana combined, and the seventh-largest subnational division in the world.
