The Atlantic subarctic upper water in the northernmost North Atlantic is the source for subarctic intermediate water and North Atlantic intermediate water. North Atlantic central water can be divided into
10842-682: The United Kingdom. The delay underscored Canada's independence. The first Canadian Army units arrived in Britain in December 1939. In all, over a million Canadians served in the armed forces during the Second World War . Canadian troops played important roles in many key battles of the war, including the failed 1942 Dieppe Raid , the Allied invasion of Italy , the Normandy landings , the Battle of Normandy , and
10981-594: The United States is the world's longest international land border. The country is characterized by a wide range of both meteorologic and geological regions. With a population of just over 41 million people, it has widely varying population densities, with the majority residing in urban areas and large areas of the country being sparsely populated. Canada's capital is Ottawa and its three largest metropolitan areas are Toronto , Montreal , and Vancouver . Indigenous peoples have continuously inhabited what
11120-455: The United States and Brazil , both increased in degree during the early 20th century, and while no major military conflicts have taken place in the Atlantic recently, the ocean remains a core component of trade around the world. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and the Americas to the west. As one component of
11259-567: The United States in 1846 ended the Oregon boundary dispute , extending the border westward along the 49th parallel . This paved the way for British colonies on Vancouver Island (1849) and in British Columbia (1858) . The Anglo-Russian Treaty of Saint Petersburg (1825) established the border along the Pacific coast, but, even after the US Alaska Purchase of 1867, disputes continued about
11398-466: The abortive Rebellions of 1837 . The Durham Report subsequently recommended responsible government and the assimilation of French Canadians into English culture. The Act of Union 1840 merged the Canadas into a united Province of Canada and responsible government was established for all provinces of British North America east of Lake Superior by 1855. The signing of the Oregon Treaty by Britain and
11537-468: The atmosphere over the oceans, keeping the British Isles and northwestern Europe mild and cloudy, and not severely cold in winter, like other locations at the same high latitude. The cold water currents contribute to heavy fog off the coast of eastern Canada (the Grand Banks of Newfoundland area) and Africa's northwestern coast. In general, winds transport moisture and air over land areas. Every winter,
11676-707: The centre of the political scale. Five parties had representatives elected to the Parliament in the 2021 election —the Liberals, who formed a minority government; the Conservatives, who became the Official Opposition ; the New Democratic Party (occupying the left ); the Bloc Québécois ; and the Green Party . Far-right and far-left politics have never been a prominent force in Canadian society. Canada has
11815-548: The constitution. The Supreme Court of Canada is the highest court, final arbiter, and has been led since 2017 by Richard Wagner , the Chief Justice of Canada . The governor general appoints the court's nine members on the advice of the prime minister and minister of justice . The federal Cabinet also appoints justices to superior courts in the provincial and territorial jurisdictions. Common law prevails everywhere except Quebec, where civil law predominates. Criminal law
11954-453: The continent during the North American fur trade . These early European interactions with First Nations would change from friendship and peace treaties to the dispossession of Indigenous lands through treaties . From the late 18th century, European Canadians forced Indigenous peoples to assimilate into a western Canadian society. Settler colonialism reached a climax in the late 19th and early 20th centuries. A period of redress began with
12093-557: The country and consists of written text and unwritten conventions. The Constitution Act, 1867 (known as the British North America Act, 1867 prior to 1982), affirmed governance based on parliamentary precedent and divided powers between the federal and provincial governments. The Statute of Westminster, 1931 , granted full autonomy, and the Constitution Act, 1982 , ended all legislative ties to Britain, as well as adding
12232-421: The country, particularly in the interior and Prairie provinces, which experience a continental climate , where daily average temperatures are near −15 °C (5 °F ), but can drop below −40 °C (−40 °F) with severe wind chills . In non-coastal regions, snow can cover the ground for almost six months of the year, while in parts of the north snow can persist year-round. Coastal British Columbia has
12371-577: The early 1930s saw an economic downturn, leading to hardship across the country. In response to the downturn, the Co-operative Commonwealth Federation (CCF) in Saskatchewan introduced many elements of a welfare state (as pioneered by Tommy Douglas ) in the 1940s and 1950s. On the advice of Prime Minister William Lyon Mackenzie King , war with Germany was declared effective September 10, 1939, by King George VI , seven days after
12510-644: The east, the boundaries of the ocean proper are Europe: the Strait of Gibraltar (where it connects with the Mediterranean Sea – one of its marginal seas – and, in turn, the Black Sea , both of which also touch upon Asia) and Africa. In the southeast, the Atlantic merges into the Indian Ocean. The 20° East meridian , running south from Cape Agulhas to Antarctica defines its border. In
12649-544: The eastern and western North Atlantic central water since the western part is strongly affected by the Gulf Stream and therefore the upper layer is closer to underlying fresher subpolar intermediate water. The eastern water is saltier because of its proximity to Mediterranean water. North Atlantic central water flows into South Atlantic central water at 15°N . There are five intermediate waters: four low-salinity waters formed at subpolar latitudes and one high-salinity formed through evaporation. Arctic intermediate water flows from
12788-624: The emergence of a new Canadian identity , marked by the adoption of the maple leaf flag in 1965, the implementation of official bilingualism (English and French) in 1969, and the institution of official multiculturalism in 1971. Socially democratic programs were also instituted, such as Medicare , the Canada Pension Plan , and Canada Student Loans ; though, provincial governments, particularly Quebec and Alberta, opposed many of these as incursions into their jurisdictions. Finally, another series of constitutional conferences resulted in
12927-719: The enclosed seas well known to the Greeks: the Mediterranean and the Black Sea. In contrast, the term "Atlantic" originally referred specifically to the Atlas Mountains in Morocco and the sea off the Strait of Gibraltar and the West African coast. The term " Aethiopian Ocean ", derived from Ancient Ethiopia , was applied to the southern Atlantic as late as the mid-19th century. During
13066-663: The exact demarcation of the Alaska–Yukon and Alaska–BC border. Following three constitutional conferences, the British North America Act, 1867 officially proclaimed Canadian Confederation on July 1, 1867, initially with four provinces: Ontario , Quebec, Nova Scotia, and New Brunswick. Canada assumed control of Rupert's Land and the North-Western Territory to form the Northwest Territories , where
13205-416: The federal government and the 10 provinces. Provincial legislatures are unicameral and operate in parliamentary fashion similar to the House of Commons. Canada's three territories also have legislatures, but these are not sovereign, have fewer constitutional responsibilities than the provinces, and differ structurally from their provincial counterparts. The Constitution of Canada is the supreme law of
13344-488: The federal jurisdiction. It is very highly ranked in international measurements of government transparency, quality of life, economic competitiveness, innovation, education and human rights. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration . Canada's long and complex relationship with the United States has had a significant impact on its history , economy , and culture . A developed country , Canada has
13483-534: The first permanent year-round European settlements at Port Royal (in 1605) and Quebec City (in 1608). Among the colonists of New France, Canadiens extensively settled the Saint Lawrence River valley and Acadians settled the present-day Maritimes , while fur traders and Catholic missionaries explored the Great Lakes , Hudson Bay , and the Mississippi watershed to Louisiana . The Beaver Wars broke out in
13622-493: The formation of a reconciliation commission by the Government of Canada in 2008. This included acknowledgment of cultural genocide , settlement agreements , and betterment of racial discrimination issues, such as addressing the plight of missing and murdered Indigenous women . It is believed that the first documented European to explore the east coast of Canada was Norse explorer Leif Erikson . In approximately 1000 AD,
13761-541: The fur trade, conflicts with the colonial authorities and settlers, and the loss of Indigenous lands to settlers and the subsequent collapse of several nations' self-sufficiency. Although not without conflict, European Canadians ' early interactions with First Nations and Inuit populations were relatively peaceful. First Nations and Métis peoples played a critical part in the development of European colonies in Canada , particularly for their role in assisting European coureurs des bois and voyageurs in their explorations of
13900-586: The growth of an independence movement in contrast to the Thirteen Colonies. The Proclamation and the Quebec Act in turn angered many residents of the Thirteen Colonies, further fuelling anti-British sentiment in the years prior to the American Revolution . After the successful American War of Independence, the 1783 Treaty of Paris recognized the independence of the newly formed United States and set
14039-727: The interconnected World Ocean , it is connected in the north to the Arctic Ocean , to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south. Other definitions describe the Atlantic as extending southward to Antarctica . The Atlantic Ocean is divided in two parts, the northern and southern Atlantic, by the Equator . The oldest known mentions of an "Atlantic" sea come from Stesichorus around mid-sixth century BC (Sch. A. R. 1. 211): Atlantikôi pelágei (Ancient Greek: Ἀτλαντικῷ πελάγει , '
14178-509: The introduction of European cattle farms and wheat fields dominating the land. The Indigenous peoples saw widespread famine and disease due to the loss of the bison and their traditional hunting lands. The federal government did provide emergency relief, on condition of the Indigenous peoples moving to the reserves. During this time, Canada introduced the Indian Act extending its control over
14317-454: The latter 2,000 km (1,200 mi). Ocean currents such as the Gulf Stream transport eel larvae from the Sargasso Sea to foraging areas in North America, Europe, and northern Africa. Recent but disputed research suggests that eels possibly use Earth's magnetic field to navigate through the ocean both as larvae and as adults. The climate is influenced by the temperatures of the surface waters and water currents as well as winds. Because of
14456-645: The limits of the oceans and seas in 1953, but some of these definitions have been revised since then and some are not recognized by various authorities, institutions, and countries, for example the CIA World Factbook . Correspondingly, the extent and number of oceans and seas vary. The Atlantic Ocean is bounded on the west by North and South America. It connects to the Arctic Ocean through the Denmark Strait , Greenland Sea , Norwegian Sea and Barents Sea . To
14595-492: The lowest values are in the high latitudes and along coasts where large rivers enter. Maximum salinity values occur at about 25° north and south , in subtropical regions with low rainfall and high evaporation. The high surface salinity in the Atlantic, on which the Atlantic thermohaline circulation is dependent, is maintained by two processes: the Agulhas Leakage/Rings , which brings salty Indian Ocean waters into
14734-761: The main front in the War of 1812 between the United States and the United Kingdom . Peace came in 1815; no boundaries were changed. Immigration resumed at a higher level, with over 960,000 arrivals from Britain between 1815 and 1850. New arrivals included refugees escaping the Great Irish Famine as well as Gaelic -speaking Scots displaced by the Highland Clearances . Infectious diseases killed between 25 and 33 percent of Europeans who immigrated to Canada before 1891. The desire for responsible government resulted in
14873-508: The margins of the continents constitute about 11% of the bottom topography with few deep channels cut across the continental rise. The mean depth between 60°N and 60°S is 3,730 m (12,240 ft), or close to the average for the global ocean, with a modal depth between 4,000 and 5,000 m (13,000 and 16,000 ft). In the South Atlantic the Walvis Ridge and Rio Grande Rise form barriers to ocean currents. The Laurentian Abyss
15012-635: The maximum depth, the Milwaukee Deep in the Puerto Rico Trench , is 8,376 m (27,480 ft). Top large seas: The bathymetry of the Atlantic is dominated by a submarine mountain range called the Mid-Atlantic Ridge (MAR).

15151-602: The mid-17th century over control of the North American fur trade. The English established additional settlements in Newfoundland in 1610 along with settlements in the Thirteen Colonies to the south. A series of four wars erupted in colonial North America between 1689 and 1763; the later wars of the period constituted the North American theatre of the Seven Years' War . Mainland Nova Scotia came under British rule with
15290-672: The monarch, the House of Commons, and the Senate . While Canada inherited the British concept of parliamentary supremacy , this was later, with the enactment of the Constitution Act, 1982, all but completely superseded by the American notion of the supremacy of the law . Each of the 338 members of Parliament in the House of Commons is elected by simple plurality in an electoral district or riding. The Constitution Act, 1982 , requires that no more than five years pass between elections, although
15429-565: The most consequential. Columbus' expedition ushered in an age of exploration and colonization of the Americas by European powers , most notably Portugal , Spain , France , and the United Kingdom . From the 16th to 19th centuries, the Atlantic Ocean was the center of both an eponymous slave trade and the Columbian exchange while occasionally hosting naval battles. Such naval battles, as well as growing trade from regional American powers like
15568-718: The most extensive and voluminous large igneous provinces in Earth's history associated with the Triassic–Jurassic extinction event , one of Earth's major extinction events . Theoliitic dikes , sills , and lava flows from the CAMP eruption at 200 Ma have been found in West Africa, eastern North America, and northern South America. The extent of the volcanism has been estimated to 4.5 × 10 km (1.7 × 10 sq mi) of which 2.5 × 10 km (9.7 × 10 sq mi) covered what
15707-630: The name of the national holiday was changed from Dominion Day to Canada Day . The first inhabitants of North America are generally hypothesized to have migrated from Siberia by way of the Bering land bridge and arrived at least 14,000 years ago. The Paleo-Indian archeological sites at Old Crow Flats and Bluefish Caves are two of the oldest sites of human habitation in Canada. The characteristics of Indigenous societies included permanent settlements, agriculture, complex societal hierarchies, and trading networks. Some of these cultures had collapsed by
15846-563: The north to become the source for North Atlantic deep water, south of the Greenland-Scotland sill. These two intermediate waters have different salinity in the western and eastern basins. The wide range of salinities in the North Atlantic is caused by the asymmetry of the northern subtropical gyre and a large number of contributions from a wide range of sources: Labrador Sea, Norwegian-Greenland Sea, Mediterranean, and South Atlantic Intermediate Water. The North Atlantic deep water (NADW)
15985-425: The ocean's great capacity to store and release heat, maritime climates are more moderate and have less extreme seasonal variations than inland climates. Precipitation can be approximated from coastal weather data and air temperature from water temperatures. The oceans are the major source of atmospheric moisture that is obtained through evaporation. Climatic zones vary with latitude; the warmest zones stretch across
16124-611: The outlines of the coasts of the Old and the New Worlds. The remainder of the ridge was discovered in the 1920s by the German Meteor expedition using echo-sounding equipment. The exploration of the MAR in the 1950s led to the general acceptance of seafloor spreading and plate tectonics . Most of the MAR runs under water but where it reaches the surfaces it has produced volcanic islands. While nine of these have collectively been nominated
16263-552: The permafrost is uncertain because the Arctic has been warming at three times the global average as a result of climate change in Canada . Canada's annual average temperature over land has risen by 1.7 °C (3.1 °F), with changes ranging from 1.1 to 2.3 °C (2.0 to 4.1 °F) in various regions, since 1948. The rate of warming has been higher across the North and in the Prairies. In
16402-581: The pond", rather than to discuss the ocean itself. The term dates to 1640, first appearing in print in a pamphlet released during the reign of Charles I , and reproduced in 1869 in Nehemiah Wallington 's Historical Notices of Events Occurring Chiefly in The Reign of Charles I , where "great Pond" is used in reference to the Atlantic Ocean by Francis Windebank , Charles I's Secretary of State . The International Hydrographic Organization (IHO) defined
16541-488: The provinces collect more revenue than the federal government, equalization payments are made by the federal government to ensure reasonably uniform standards of services and taxation are kept between the richer and poorer provinces. The major difference between a Canadian province and a territory is that provinces receive their sovereignty from the Crown and power and authority from the Constitution Act, 1867 , whereas territorial governments have powers delegated to them by
16680-736: The rights they support were reaffirmed by section 35 of the Constitution Act, 1982 . These rights may include provision of services, such as healthcare through the Indian Health Transfer Policy , and exemption from taxation. Canada is a federation composed of 10 federated states , called provinces, and three federal territories . These may be grouped into four main regions : Western Canada , Central Canada , Atlantic Canada , and Northern Canada ( Eastern Canada refers to Central Canada and Atlantic Canada together). Provinces and territories have responsibility for social programs such as healthcare , education , and social programs , as well as administration of justice (but not criminal law). Although
16819-438: The seafloor. The oldest oceanic crust in the Atlantic is up to 145 million years and is situated off the west coast of Africa and the east coast of North America, or on either side of the South Atlantic. In many places, the continental shelf and continental slope are covered in thick sedimentary layers. For instance, on the North American side of the ocean, large carbonate deposits formed in warm shallow waters such as Florida and
16958-585: The southeast. Canada is also home to the world's northernmost settlement, Canadian Forces Station Alert , on the northern tip of Ellesmere Island —latitude 82.5°N—which lies 817 kilometres (508 mi) from the North Pole. In latitude, Canada's most northerly point of land is Cape Columbia in Nunavut at 83°6′41″N, with its southern extreme at Middle Island in Lake Erie at 41°40′53″N. In longitude, Canada's land extends from Cape Spear , Newfoundland, at 52°37'W, to Mount St. Elias , Yukon Territory, at 141°W. Canada can be divided into seven physiographic regions:
17097-422: The southern regions of Canada, air pollution from both Canada and the United States—caused by metal smelting, burning coal to power utilities, and vehicle emissions—has resulted in acid rain , which has severely impacted waterways, forest growth, and agricultural productivity. Canada is one of the largest greenhouse gas emitters globally , with emissions increased by 16.5 percent between 1990 and 2022. Canada
17236-413: The subtropics to the northeastern Atlantic. There this water is cooled during winter and forms return currents that merge along the eastern continental slope of Greenland where they form an intense (40–50 Sv ) current which flows around the continental margins of the Labrador Sea . A third of this water becomes part of the deep portion of the North Atlantic Deep Water (NADW). The NADW, in turn, feeds
17375-421: The surface is usually covered with sea ice in the Labrador Sea , Denmark Strait , and Baltic Sea. The Coriolis effect circulates North Atlantic water in a clockwise direction, whereas South Atlantic water circulates counter-clockwise. The south tides in the Atlantic Ocean are semi-diurnal; that is, two high tides occur every 24 lunar hours. In latitudes above 40° North some east–west oscillation, known as
17514-438: The terms of peace, ceding British North American territories south of the Great Lakes and east of the Mississippi River to the new country. The American war of independence also caused a large out-migration of Loyalists , the settlers who had fought against American independence. Many moved to Canada, particularly Atlantic Canada, where their arrival changed the demographic distribution of the existing territories. New Brunswick
17653-446: The time European explorers arrived in the late 15th and early 16th centuries and have only been discovered through archeological investigations. Indigenous peoples in present-day Canada include the First Nations , Inuit , and Métis , the last being of mixed descent who originated in the mid-17th century when First Nations people married European settlers and subsequently developed their own identity. The Indigenous population at
17792-446: The time of the first European settlements is estimated to have been between 200,000 and two million, with a figure of 500,000 accepted by Canada's Royal Commission on Aboriginal Peoples . As a consequence of European colonization, the Indigenous population declined by forty to eighty percent. The decline is attributed to several causes, including the transfer of European diseases , to which they had no natural immunity, conflicts over
17931-428: The total volume of the Earth's oceans. Excluding its marginal seas, the Atlantic covers 81,760,000 km (31,570,000 sq mi) and has a volume of 305,811,900 km (73,368,200 cu mi). The North Atlantic covers 41,490,000 km (16,020,000 sq mi) (11.5%) and the South Atlantic 40,270,000 km (15,550,000 sq mi) (11.1%). The average depth is 3,646 m (11,962 ft) and

18209-453: The upper layers of the circumpolar region, near the Drake Passage and the Falkland Islands. Both these currents receive some contribution from the Indian Ocean. On the African east coast, the small cyclonic Angola Gyre lies embedded in the large subtropical gyre. The southern subtropical gyre is partly masked by a wind-induced Ekman layer . The residence time of the gyre is 4.4–8.5 years. North Atlantic Deep Water flows southward below
18348-410: The village of Stadacona . Cartier later used the word Canada to refer not only to that particular village but to the entire area subject to Donnacona (the chief at Stadacona); by 1545, European books and maps had begun referring to this small region along the Saint Lawrence River as Canada . From the 16th to the early 18th century, Canada referred to the part of New France that lay along
18487-423: The war with a large army and strong economy. The financial crisis of the Great Depression led the Dominion of Newfoundland to relinquish responsible government in 1934 and become a Crown colony ruled by a British governor. After two referendums , Newfoundlanders voted to join Canada in 1949 as a province. Canada's post-war economic growth, combined with the policies of successive Liberal governments, led to
18626-428: The war. The Conscription Crisis of 1917 erupted when the Unionist Cabinet's proposal to augment the military's dwindling number of active members with conscription was met with vehement objections from French-speaking Quebecers. In 1919, Canada joined the League of Nations independently of Britain, and the Statute of Westminster, 1931 , affirmed Canada's independence. The Great Depression in Canada during
18765-424: The western Atlantic and South Sandwich Trench (8,264 m or 27,113 ft) in the South Atlantic. There are numerous submarine canyons off northeastern North America, western Europe, and northwestern Africa. Some of these canyons extend along the continental rises and farther into the abyssal plains as deep-sea channels. In 1922, a historic moment in cartography and oceanography occurred. The USS Stewart used
18904-410: The world's longest coastline of 243,042 kilometres (151,019 mi). In addition to sharing the world's largest land border with the United States —spanning 8,891 km (5,525 mi) —Canada shares a land border with Greenland (and hence the Kingdom of Denmark ) to the northeast, on Hans Island , and a maritime boundary with France 's overseas collectivity of Saint Pierre and Miquelon to
19043-427: Was adopted as the legal name for the new country at the London Conference and the word dominion was conferred as the country's title. By the 1950s, the term Dominion of Canada was no longer used by the United Kingdom, which considered Canada a "realm of the Commonwealth". The Canada Act 1982 , which brought the Constitution of Canada fully under Canadian control, referred only to Canada . Later that year,
19182-507: Was in turn split from Nova Scotia as part of a reorganization of Loyalist settlements in the Maritimes, which led to the incorporation of Saint John, New Brunswick , as Canada's first city. To accommodate the influx of English-speaking Loyalists in Central Canada, the Constitutional Act of 1791 divided the province of Canada into French-speaking Lower Canada (later Quebec ) and English-speaking Upper Canada (later Ontario ), granting each its own elected legislative assembly. The Canadas were
19321-430: Was passed by Parliament, outlining the terms of a negotiated departure from Confederation. In addition to the issues of Quebec sovereignty, a number of crises shook Canadian society in the late 1980s and early 1990s. These included the explosion of Air India Flight 182 in 1985, the largest mass murder in Canadian history; the École Polytechnique massacre in 1989, a university shooting targeting female students; and
