The borders of Canada include:
Canada has a vast geography that occupies much of the continent of North America, sharing a land border with the contiguous United States to the south and the U.S. state of Alaska to the northwest. Canada stretches from the Atlantic Ocean in the east to the Pacific Ocean in the west; to the north lies the Arctic Ocean. Greenland is to the northeast with a shared border on Hans Island. To the southeast Canada shares a maritime boundary with France's overseas collectivity of Saint Pierre and Miquelon, the last vestige of New France. By total area, Canada is the second-largest country in the world, after Russia. By land area alone, however, Canada ranks fourth, the difference being due to it having the world's largest proportion of fresh water lakes. Of Canada's thirteen provinces and territories, only two are landlocked while the other eleven all directly border one of three oceans.
The Northwest Territories is a federal territory of Canada. At a land area of approximately 1,127,711.92 km2 (435,412.01 sq mi) and a 2021 census population of 41,070, it is the second-largest and the most populous of the three territories in Northern Canada. Its estimated population as of the second quarter of 2024 is 44,920. 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.
Labrador is a geographic and cultural region within the Canadian province of Newfoundland and Labrador. It is the primarily continental portion of the province and constitutes 71% of the province's area but is home to only 6% of its population. It is separated from the island of Newfoundland by the Strait of Belle Isle. It is the largest and northernmost geographical region in the four Atlantic provinces.
Northern 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 foreign relations of Canada are Canada's relations with other governments and nations. Canada is recognized as a middle power for its role in global affairs with a tendency to pursue multilateral and international solutions. Canada is known for its strong commitment to international peace and security, as well as being a mediator in conflicts, and for providing aid to developing countries. The "golden age of Canadian diplomacy" refers to a period in Canadian history, typically considered to be the mid-20th century, when Canada experienced a high level of success in its foreign relations and diplomatic efforts.
Hans Island is an island in the centre of the Kennedy Channel of Nares Strait in the high Arctic region, split between the Canadian territory of Nunavut and the Danish autonomous territory of Greenland. The island itself is barren and uninhabited with an area of 130 hectares, measuring 1,290 by 1,199 metres, and a maximum elevation of 168.17 m (551.7 ft). Its location in the strait that separates Ellesmere Island of Canada from northern Greenland was for years a border dispute, the so-called Whisky War between the two countries of Canada and Denmark. Hans Island is the smallest of three islands in Kennedy Channel off the Washington Land coast; the others are Franklin Island and Crozier Island. The strait at this point is 35 km (22 mi) wide, placing the island within the territorial waters of both Canada and Denmark (Greenland). A 1,280-metre-long (4,200 ft) shared border traverses the island.
The Beaufort Sea is a marginal sea of the Arctic Ocean, located north of the Northwest Territories, Yukon, and Alaska, and west of the Canadian Arctic Archipelago. The sea is named after Sir Francis Beaufort, a hydrographer. The Mackenzie River, the longest in Canada, empties into the Canadian part of the Beaufort Sea west of Tuktoyaktuk, which is one of the few permanent settlements on the sea's shores.
An exclusive economic zone (EEZ), as prescribed by the 1982 United Nations Convention on the Law of the Sea, is an area of the sea in which a sovereign state has exclusive rights regarding the exploration and use of marine resources, including energy production from water and wind.
Nunavut is the largest, easternmost, and northernmost territory of Canada. It was separated officially from the Northwest Territories on April 1, 1999, via the Nunavut Act and the Nunavut Land Claims Agreement Act, which provided this territory to the Inuit for self-government. The boundaries had been drawn in 1993. The creation of Nunavut resulted in the first major change to Canada's political map in half a century since the province of Newfoundland was admitted in 1949.
The United States has land borders with only Canada and Mexico, both of them long. It has maritime boundaries with many countries due to its extensive exclusive economic zone (EEZ). All of its maritime borders with Canada are at least partially disputed, and its territorial claims on three Caribbean islands are disputed.
The Arctic consists of land, internal waters, territorial seas, exclusive economic zones (EEZs) and international waters above the Arctic Circle. All land, internal waters, territorial seas and EEZs in the Arctic are under the jurisdiction of one of the eight Arctic coastal states: Canada, Denmark, Finland, Iceland, Norway, Russia, Sweden and the United States. International law regulates this area as with other portions of Earth.
The continental shelf of the United States is the total of the continental shelves adjacent to the United States. In marine geology, it is the elevated seabed near US coasts; in the political sense, it is the area claimed by the United States as sovereign, according to the United Nations Convention on the Law of the Sea.
A number of states and polities formerly claimed colonies and territories in Canada prior to the evolution of the current provinces and territories under the federal system. North America prior to colonization was occupied by a variety of indigenous groups consisting of band societies typical of the sparsely populated North, to loose confederacies made up of numerous hunting bands from a variety of ethnic groups, to more structured confederacies of sedentary farming villages, to stratified hereditary structures centred on a fishing economy. The colonization of Canada by Europeans began in the 10th century, when Norsemen explored and, ultimately unsuccessfully, attempted to settle areas of the northeastern fringes of North America. Early permanent European settlements in what is now Canada included the late 16th and 17th century French colonies of Acadia and Canada, the English colonies of Newfoundland (island) and Rupert's Land, the Scottish colonies of Nova Scotia and Port Royal.
Arctic cooperation and politics are partially coordinated via the Arctic Council, composed of the eight Arctic states: the United States, Canada, Iceland, Norway, Sweden, Finland, Russia, and Denmark with Greenland and the Faroe Islands. The dominant governmental power in Arctic policy resides within the executive offices, legislative bodies, and implementing agencies of the eight Arctic countries, and to a lesser extent other countries, such as United Kingdom, Germany, European Union and China. NGOs and academia play a large part in Arctic policy. Also important are intergovernmental bodies such as the United Nations and NATO.
The Arctic Policy of the Kingdom of Denmark defines the Kingdom's foreign relations and policies with other Arctic countries, and the Kingdom's strategy for the Arctic on issues occurring within the geographic boundaries of "the Arctic" or related to the Arctic or its peoples. In order to clearly understand the Danish geopolitical importance of the Arctic, it is necessary to mention Denmark's territorial claims in areas beyond its exclusive EEZ in areas around the Faroe Islands and north of Greenland covering parts of the North Pole, which is also claimed by Russia.
The Whisky War, also known as the Liquor Wars, was a bloodless war and border dispute between the Kingdom of Denmark and Canada over Hans Island. Between 1973 and 2022, the island was under dispute between the two nations, although never amounting to direct conflict or violence.
The United States has the world's second-largest exclusive economic zone (EEZ). The total size is 11,351,000 km2 (4,383,000 sq mi)2. Areas of its EEZ are located in three oceans, the Gulf of Mexico, and the Caribbean Sea. Most notable areas are Alaska, Hawaii, the East Coast, West Coast and Gulf Coast of the United States.
