Nunavut in the context of "Canadian Forces Station Alert"

Northern Canada (French: le Nord du Canada), colloquially the North or the Territories, is the vast northernmost region of Canada, variously defined by geography and politics. Politically, the term refers to the three territories of Canada: Yukon, Northwest Territories and Nunavut. This area covers about 48 per cent of Canada's total land area, but has less than 0.5 per cent of Canada's population.

The terms "northern Canada" or "the North" may be used in contrast with the far north, which may refer to the Canadian Arctic, the portion of Canada that lies north of the Arctic Circle, east of Alaska and west of Greenland. That said, in many other uses the two areas are treated as a single unit.

The Arctic Archipelago, also known as the Canadian Arctic Archipelago, is an archipelago lying to the north of the Canadian continental mainland, excluding Greenland (an autonomous territory of the Danish Realm, which is, by itself, much larger than the combined area of the archipelago), and Iceland (an independent country).

Situated in the northern extremity of North America and covering about 1,424,500 km (550,000 sq mi), this group of 36,563 islands, surrounded by the Arctic Ocean, comprises much of Northern Canada, predominately Nunavut and the Northwest Territories. The archipelago is showing some effects of climate change, with some computer estimates determining that melting there will contribute 3.5 cm (1.4 in) to the rise in sea levels by 2100.

Quebec (French: Québec) is Canada's largest province by area. Located in Central Canada, the province shares borders with the provinces of Ontario to the west, Newfoundland and Labrador to the northeast, New Brunswick to the southeast and a coastal border with the territory of Nunavut. In the south, it shares a border with the United States. Quebec has a population of around 8 million, making it Canada's second-most populous province only behind Ontario.

Between 1534 and 1763, what is now Quebec was the French colony of Canada and was the most developed colony in New France. Following the Seven Years' War, Canada became a British colony, first as the Province of Quebec (1763–1791), then Lower Canada (1791–1841), and lastly part of the Province of Canada (1841–1867) as a result of the Lower Canada Rebellion. It was confederated with Ontario, Nova Scotia, and New Brunswick in 1867. Until the early 1960s, the Catholic Church played a large role in the social and cultural institutions in Quebec. However, the Quiet Revolution of the 1960s to 1980s increased the role of the Government of Quebec in l'État québécois (the public authority of Quebec).

James Bay (French: Baie James, pronounced [bɛ dʒɛmz]; Cree: ᐐᓂᐯᒄ, romanized: Wînipekw, lit. 'dirty water') is a body of water located on the southern end of Hudson Bay in Canada. It borders the provinces of Quebec and Ontario, and is politically part of Nunavut. Its largest island is Akimiski Island.

Numerous waterways of the James Bay watershed have been modified with dams or diversion for several major hydroelectric projects. These waterways are also destinations for river-based recreation. Several communities are located near or alongside James Bay, including a number of Aboriginal Canadian communities, such as the Kashechewan First Nation and nine communities affiliated with the Cree of northern Quebec.

Hudson Bay, sometimes called Hudson's Bay (usually historically), is a large body of saltwater in northeastern Canada with a surface area of 1,230,000 km (470,000 sq mi). It is located north of Ontario, west of Quebec, northeast of Manitoba, and southeast of Nunavut, but politically entirely part of Nunavut. It is an inland marginal sea of the Arctic Ocean. The Hudson Strait provides a connection to the Labrador Sea and the Atlantic Ocean in the northeast, while the Foxe Channel connects Hudson Bay with the Arctic Ocean in the north. The Hudson Bay drainage basin drains a very large area, about 3,861,400 km (1,490,900 sq mi), that includes parts of southeastern Nunavut, Alberta, Saskatchewan, Ontario, Quebec, all of Manitoba, and parts of the U.S. states of North Dakota, South Dakota, Minnesota, and Montana. Hudson Bay's southern arm is called James Bay.

The Eastern Cree name for Hudson and James Bay is Wînipekw (southern dialect) or Wînipâkw (northern dialect), meaning muddy or brackish water. Lake Winnipeg is similarly named by the local Cree, as is the location for the city of Winnipeg.

The Arctic (/ˈɑːr(k)tɪk/; from Ancient Greek ἄρκτος (árktos) 'bear') is the polar region of Earth that surrounds the North Pole, lying north of the Arctic Circle. The Arctic region, from the IERS Reference Meridian travelling east, consists of parts of northern Norway (Nordland, Troms, Finnmark, Svalbard and Jan Mayen), northernmost Sweden (Västerbotten, Norrbotten and Lappland), northern Finland (North Ostrobothnia, Kainuu and Lappi), Russia (Murmansk, Siberia, Nenets Okrug, Novaya Zemlya), the United States (Alaska), Canada (Yukon, Northwest Territories, Nunavut), Danish Realm (Greenland), and northern Iceland (Grímsey and Kolbeinsey), along with the Arctic Ocean and adjacent seas.

Land within the Arctic region has seasonally varying snow and ice cover, with predominantly treeless permafrost under the tundra. Arctic seas contain seasonal sea ice in many places.

The Numbered Treaties (or Post-Confederation Treaties) are a series of eleven treaties signed between the First Nations, one of three groups of Indigenous Peoples in Canada, and the reigning monarch of Canada (Victoria, Edward VII or George V) from 1871 to 1921. These agreements were created to allow the Government of Canada to pursue settlement and resource extraction in the affected regions, which includes the entirety of modern-day Alberta, Manitoba, and Saskatchewan, as well as parts of modern-day British Columbia, Ontario, the Northwest Territories, Nunavut, and Yukon. These treaties expanded the Dominion of Canada resulting in the displacement of Indigenous populations for large tracts of land in exchange for promises made to the indigenous people of the area. These terms were dependent on individual negotiations and so specific terms differed with each treaty.

These treaties came in two waves—Numbers 1 through 7 from 1871 to 1877 and Numbers 8 through 11 from 1899 to 1921. In the first wave, the treaties were key in advancing European settlement across the Prairie regions as well as the development of the Canadian Pacific Railway. In the second wave, resource extraction was the main motive for government officials. During this time, Canada introduced the Indian Act extending its control over the First Nations to education, government and legal rights. The federal government did provide emergency relief, on condition of the Indigenous peoples moving to the Indian reserve.

Newfoundland and Labrador is the easternmost province of Canada, in the country's Atlantic region. The province comprises the island of Newfoundland and the continental region of Labrador, having a total size of 405,212 km (156,453 sq mi). As of 2025 the population of Newfoundland and Labrador was estimated to be 549,911. The island of Newfoundland (and its smaller neighbouring islands) is home to around 94 per cent of the province's population, with more than half residing in the Avalon Peninsula. Labrador has a land border with both the province of Quebec, as well as a short border with the territory of Nunavut on Killiniq Island. The French overseas collectivity of Saint Pierre and Miquelon lies about 20 km (12 mi) west of the Burin Peninsula.

According to the 2016 census, 97.0% of residents reported English as their native language, making Newfoundland and Labrador Canada's most linguistically homogeneous province. Much of the population is descended from English and Irish settlers, with the majority immigrating from the early 17th century to the late 19th century.St. John's, the capital and largest city of Newfoundland and Labrador, is Canada's 22nd-largest census metropolitan area and home to about 40% of the province's population. St. John's is the seat of the House of Assembly of Newfoundland and Labrador as well as the province's highest court, the Newfoundland and Labrador Court of Appeal.

Post-glacial rebound (also called isostatic rebound or crustal rebound) is the rise of land masses after the removal of the huge weight of ice sheets during the last glacial period, which had caused isostatic depression. Post-glacial rebound and isostatic depression are phases of glacial isostasy (glacial isostatic adjustment, glacioisostasy), the deformation of the Earth's crust in response to changes in ice mass distribution. The direct raising effects of post-glacial rebound are readily apparent in parts of Northern Eurasia, Northern America, Patagonia, and Antarctica. However, through the processes of ocean siphoning and continental levering, the effects of post-glacial rebound on sea level are felt globally far from the locations of current and former ice sheets.

The Northwest Territories is a federal territory of Canada. At a land area of approximately 1,127,711.92 km (435,412.01 sq mi) and a 2021 census population of 41,070, it was the second-largest and the most populous of the three territories in Northern Canada. Its estimated population as of the third quarter of 2025 is 45,950 which would make it the second most populous of the three territories. Yellowknife is the capital, most populous community, and the only city in the territory; its population was 20,340 as of the 2021 census. It became the territorial capital in 1967, following recommendations by the Carrothers Commission.

The Northwest Territories, a portion of the old North-Western Territory, entered the Canadian Confederation on July 15, 1870. At first, it was named the North-West Territories. The name was changed to the present Northwest Territories in 1906. Since 1870, the territory has been divided four times to create new provinces and territories or enlarge existing ones. Its current borders date from April 1, 1999, when the territory's size was decreased again by the creation of a new territory of Nunavut to the east, through the Nunavut Act and the Nunavut Land Claims Agreement. While Nunavut is mostly Arctic tundra, the Northwest Territories has a slightly warmer climate and is both boreal forest (taiga) and tundra, and its most northern regions form part of the Arctic Archipelago.
