97-560: The major events of this era are the breakup of the Columbia supercontinent , the formation of the Rodinia supercontinent , and the evolution of sexual reproduction . This era is marked by the further development of continental plates and plate tectonics . The supercontinent of Columbia broke up between 1500 and 1350 million years ago, and the fragments reassembled into the supercontinent of Rodinia around 1100 to 900 million years ago, on

194-451: A high nominal per capita income globally and its advanced economy ranks among the largest in the world by nominal GDP , relying chiefly upon its abundant natural resources and well-developed international trade networks . Recognized as a middle power , Canada's strong support for multilateralism and internationalism has been closely related to its foreign relations policies of peacekeeping and aid for developing countries . Canada

291-467: A parliamentary system within the context of a constitutional monarchy —the monarchy of Canada being the foundation of the executive, legislative , and judicial branches. The reigning monarch is also monarch of 14 other sovereign Commonwealth countries and Canada's 10 provinces . The monarch appoints a representative, the governor general , on the advice of the prime minister , to carry out most of their ceremonial royal duties. The monarchy

388-421: 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 is now Canada for thousands of years. Beginning in

485-662: A 10-metre (33 ft) cross bearing the words, "long live the King of France", and took possession of the territory New France in the name of King Francis I . The early 16th century saw European mariners with navigational techniques pioneered by the Basque and Portuguese establish seasonal whaling and fishing outposts along the Atlantic coast. In general, early settlements during the Age of Discovery appear to have been short-lived due to

582-642: A combination of the harsh climate, problems with navigating trade routes and competing outputs in Scandinavia. In 1583, Sir Humphrey Gilbert , by the royal prerogative of Queen Elizabeth I , founded St John's, Newfoundland , as the first North American English seasonal camp . In 1600, the French established their first seasonal trading post at Tadoussac along the Saint Lawrence. French explorer Samuel de Champlain arrived in 1603 and established

679-567: A constitutional amending formula and the Canadian Charter of Rights and Freedoms . The Charter guarantees basic rights and freedoms that usually cannot be overridden by any government; a notwithstanding clause allows Parliament and the provincial legislatures to override certain sections of the Charter for a period of five years. Canada's judiciary interprets laws and has the power to strike down acts of Parliament that violate

776-506: A distinguishing element of Canada's political culture. Peace, order, and good government , alongside an Implied Bill of Rights , are founding principles of Canadian federalism . At the federal level, Canada has been dominated by two relatively centrist parties practising "brokerage politics": the centre-left leaning Liberal Party of Canada and the centre-right leaning Conservative Party of Canada (or its predecessors ). The historically predominant Liberals position themselves at

873-759: A great magmatic accretionary belt along the present-day southern margin of North America, Greenland, and Baltica. It includes the 1.8–1.7 Ga Yavapai, Central Plains and Makkovikian Belts, 1.7–1.6 Ga Mazatzal and Labradorian Belts, 1.5–1.3 Ga St. Francois and Spavinaw Belts , and 1.3–1.2 Ga Elzevirian Belt in North America; the 1.8–1.7 Ga Ketilidian Belt in Greenland; and the 1.8–1.7 Transscandinavian Igneous Belt, 1.7–1.6 Ga Kongsberggian-Gothian Belt, and 1.5–1.3 Ga Southwest Sweden Granitoid Belt in Baltica. Other cratonic blocks also underwent marginal outgrowth at about

970-431: A temperate climate, with a mild and rainy winter. On the east and west coasts, average high temperatures are generally in the low 20s °C (70s °F), while between the coasts, the average summer high temperature ranges from 25 to 30 °C (77 to 86 °F), with temperatures in some interior locations occasionally exceeding 40 °C (104 °F). Much of Northern Canada is covered by ice and permafrost . The future of

1164-554: Is divided into 15 terrestrial and five marine ecozones . These ecozones encompass over 80,000 classified species of Canadian wildlife , with an equal number yet to be formally recognized or discovered. Although Canada has a low percentage of endemic species compared to other countries , due to human activities, invasive species , and environmental issues in the country , there are currently more than 800 species at risk of being lost . About 65 percent of Canada's resident species are considered "Secure". Over half of Canada's landscape

1261-498: Is estimated to have been approximately 12,900 km (8,000 mi) from north to south at its broadest part. The eastern coast of India was attached to western North America , with southern Australia against western Canada . In the Paleoproterozoic most of South America was rotated such that the western edge of modern-day Brazil lined up with eastern North America, forming a continental margin that extended into

1358-1026: Is intact and relatively free of human development. The boreal forest of Canada is considered to be the largest intact forest on Earth, with approximately 3,000,000 km (1,200,000 sq mi) undisturbed by roads, cities or industry. Since the end of the last glacial period , Canada has consisted of eight distinct forest regions . Approximately 12.1 percent of the nation's landmass and freshwater are conservation areas , including 11.4 percent designated as protected areas . Approximately 13.8 percent of its territorial waters are conserved, including 8.9 percent designated as protected areas. Canada's first National Park , Banff National Park established in 1885 spans 6,641 square kilometres (2,564 sq mi). Canada's oldest provincial park, Algonquin Provincial Park , established in 1893, covers an area of 7,653.45 square kilometres (2,955.01 sq mi). Lake Superior National Marine Conservation Area

1455-457: Is part of multiple international organizations and forums . While a variety of theories have been postulated for the etymological origins of Canada , the name is now accepted as coming from the St. Lawrence Iroquoian word kanata , meaning "village" or "settlement". In 1535, Indigenous inhabitants of the present-day Quebec City region used the word to direct French explorer Jacques Cartier to

1552-687: Is solely a federal responsibility and is uniform throughout Canada. Law enforcement, including criminal courts, is officially a provincial responsibility, conducted by provincial and municipal police forces. In most rural and some urban areas, policing responsibilities are contracted to the federal Royal Canadian Mounted Police . Canadian Aboriginal law provides certain constitutionally recognized rights to land and traditional practices for Indigenous groups in Canada. Various treaties and case laws were established to mediate relations between Europeans and many Indigenous peoples. The role of Aboriginal law and

1649-399: Is the second-largest country . By land area alone, Canada ranks fourth , due to having the world's largest area of fresh water lakes . Stretching from the Atlantic Ocean in the east, along the Arctic Ocean to the north, and to the Pacific Ocean in the west, the country encompasses 9,984,670 km (3,855,100 sq mi) of territory. Canada also has vast maritime terrain, with

1746-521: Is the source of sovereignty and authority in Canada. However, while the governor general or monarch may exercise their power without ministerial advice in rare crisis situations , the use of the executive powers (or royal prerogative ) is otherwise directed by the Cabinet , a committee of ministers of the Crown responsible to the elected House of Commons and chosen and headed by the prime minister,

1843-562: Is the world's largest freshwater protected area, spanning roughly 10,000 square kilometres (3,900 sq mi). Canada's largest national wildlife region is the Scott Islands Marine National Wildlife Area which spans 11,570.65 square kilometres (4,467.45 sq mi). Canada is described as a " full democracy ", with a tradition of liberalism , and an egalitarian , moderate political ideology. An emphasis on social justice has been

1940-666: The Canada Elections Act limits this to four years with a "fixed" election date in October; general elections still must be called by the governor general and can be triggered by either the advice of the prime minister or a lost confidence vote in the House. The 105 members of the Senate, whose seats are apportioned on a regional basis, serve until age 75. Canadian federalism divides government responsibilities between

2037-705: The Dominion Lands Act to regulate settlement and established the North-West Mounted Police to assert authority over the territory. This period of westward expansion and nation building resulted in the displacement of many Indigenous peoples of the Canadian Prairies to " Indian reserves ", clearing the way for ethnic European block settlements . This caused the collapse of the Plains Bison in western Canada and

2134-775: The Battle of the Scheldt in 1944. Canada provided asylum for the Dutch monarchy while that country was occupied and is credited by the Netherlands for major contributions to its liberation from Nazi Germany . The Canadian economy boomed during the war as its industries manufactured military materiel for Canada, Britain, China , and the Soviet Union . Despite another Conscription Crisis in Quebec in 1944, Canada finished

2231-612: The COVID-19 pandemic in Canada began on January 27, 2020, with widespread social and economic disruption. In 2021, the possible graves of hundreds of Indigenous people were discovered near the former sites of Canadian Indian residential schools . Administered by various Christian churches and funded by the Canadian government from 1828 to 1997, these boarding schools attempted to assimilate Indigenous children into Euro-Canadian culture . By total area (including its waters), Canada

2328-649: The Canada Act 1982 , the patriation of Canada's constitution from the United Kingdom, concurrent with the creation of the Canadian Charter of Rights and Freedoms . Canada had established complete sovereignty as an independent country under its own monarchy . In 1999, Nunavut became Canada's third territory after a series of negotiations with the federal government. At the same time, Quebec underwent profound social and economic changes through

2425-826: The Canadian Shield , the interior plains , the Great Lakes-St. Lawrence Lowlands , the Appalachian region , the Western Cordillera , Hudson Bay Lowlands , and the Arctic Archipelago . Boreal forests prevail throughout the country, ice is prominent in northern Arctic regions and through the Rocky Mountains , and the relatively flat Canadian Prairies in the southwest facilitate productive agriculture. The Great Lakes feed

2522-726: The Ectasian (1400 to 1200 Mya), and the Stenian (1200 to 1000 Mya). The Calymmian and Ectasian were characterized by stabilization and expansion of cratonic covers and the Stenian by formation of orogenic belts. The time period from 1780 Ma to 850 Ma, an unofficial period based on stratigraphy rather than chronometry , named the Rodinian , is described in the geological timescale review 2012 edited by Gradstein et al., but as of February 2017, this has not yet been officially adopted by

2619-802: The Gawler Craton . In China, a 1.8–1.4 Ga accretionary magmatic zone, called the Xiong’er belt (Group), extends along the southern margin of the North China Craton. Columbia began to fragment about 1.5–1.35 Ga, associated with continental rifting along the western margin of Laurentia (Belt-Purcell Supergroup), eastern India (Mahanadi and the Godavari), southern margin of Baltica (Telemark Supergroup), southeastern margin of Siberia ( Riphean aulacogens ), northwestern margin of South Africa (Kalahari Copper Belt), and northern margin of

2716-535: The International Union of Geological Sciences (IUGS). Columbia (supercontinent) Columbia , also known as Nuna or Hudsonland , is a hypothetical ancient supercontinent . It was first proposed by John J.W. Rogers and M. Santosh in 2002 and is thought to have existed approximately 2,500 to 1,500 million years ago (Ma), in the Paleoproterozoic era. The assembly of

2813-769: The Meech Lake Accord failed in 1990. This led to the formation of the Bloc Québécois in Quebec and the invigoration of the Reform Party of Canada in the West. A second referendum followed in 1995, in which sovereignty was rejected by a slimmer margin of 50.6 to 49.4 percent. In 1997, the Supreme Court ruled unilateral secession by a province would be unconstitutional, and the Clarity Act

2910-696: The Oka Crisis of 1990, the first of a number of violent confrontations between provincial governments and Indigenous groups. Canada joined the Gulf War in 1990 and was active in several peacekeeping missions in the 1990s, including operations in the Balkans during and after the Yugoslav Wars , and in Somalia , resulting in an incident that has been described as " the darkest era in the history of

3007-620: The Parliament of Canada and the commissioners represent the King in his federal Council , rather than the monarch directly. The powers flowing from the Constitution Act, 1867 , are divided between the federal government and the provincial governments to exercise exclusively and any changes to that arrangement require a constitutional amendment , while changes to the roles and powers of the territories may be performed unilaterally by

Mesoproterozoic - Misplaced Pages Continue

3104-595: The Proterozoic core of Laurentia plus Baltica. Because Hoffman published his name earlier than Rogers and Santosh published theirs, there have been calls to use Nuna rather than Columbia , on the basis of scientific precedence. However, Nuna was essentially equivalent to an earlier Nena , and neither clearly referred to an early supercontinent as Columbia did, rather than merely the core of this earlier supercontinent. Other earlier speculative continents included Hudsonland and Arctica , but Rogers and Santosh were

3201-554: The Quiet Revolution of the 1960s, giving birth to a secular nationalist movement. The radical Front de libération du Québec (FLQ) ignited the October Crisis with a series of bombings and kidnappings in 1970, and the sovereigntist Parti Québécois was elected in 1976, organizing an unsuccessful referendum on sovereignty-association in 1980. Attempts to accommodate Quebec nationalism constitutionally through

3298-781: The St. Lawrence River (in the southeast) where the lowlands host much of Canada's economic output. Canada has over 2,000,000 lakes—563 of which are larger than 100 km (39 sq mi)—containing much of the world's fresh water . There are also fresh-water glaciers in the Canadian Rockies , the Coast Mountains , and the Arctic Cordillera . Canada is geologically active , having many earthquakes and potentially active volcanoes . Average winter and summer high temperatures across Canada vary from region to region. Winters can be harsh in many parts of

3395-459: The Westminster tradition . The country's head of government is the prime minister , who holds office by virtue of their ability to command the confidence of the elected House of Commons and is appointed by the governor general , representing the monarch of Canada , the ceremonial head of state . The country is a Commonwealth realm and is officially bilingual (English and French) in

3492-510: The displacement of Indigenous populations , and a process of increasing autonomy from the United Kingdom. This increased sovereignty was highlighted by the Statute of Westminster, 1931 , and culminating in the Canada Act 1982 , which severed the vestiges of legal dependence on the Parliament of the United Kingdom . Canada is a parliamentary democracy and a constitutional monarchy in

3589-441: The head of government . To ensure the stability of government, the governor general will usually appoint as prime minister the individual who is the current leader of the political party that can obtain the confidence of a majority of members in the House. The Prime Minister's Office (PMO) is one of the most powerful institutions in government, initiating most legislation for parliamentary approval and selecting for appointment by

3686-445: The 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts , France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation , Canada was formed as a federal dominion of four provinces. This began an accretion of provinces and territories resulting in

3783-579: The 1713 Treaty of Utrecht and Canada and most of New France came under British rule in 1763 after the Seven Years' War. The Royal Proclamation of 1763 established First Nation treaty rights, created the Province of Quebec out of New France, and annexed Cape Breton Island to Nova Scotia. St John's Island (now Prince Edward Island ) became a separate colony in 1769. To avert conflict in Quebec ,

3880-719: The British Parliament passed the Quebec Act 1774, expanding Quebec's territory to the Great Lakes and Ohio Valley . More importantly, the Quebec Act afforded Quebec special autonomy and rights of self-administration at a time when the Thirteen Colonies were increasingly agitating against British rule. It re-established the French language, Catholic faith, and French civil law there, staving off

3977-759: The Canadian military ". Canada sent troops to Afghanistan in 2001 , resulting in the largest amount of Canadian deaths for any single military mission since the Korean War in the early 1950s. In 2011, Canadian forces participated in the NATO-led intervention into the Libyan Civil War and also became involved in battling the Islamic State insurgency in Iraq in the mid-2010s. The country celebrated its sesquicentennial in 2017, three years before

The leader of the party with the second-most seats usually becomes the leader of the Official Opposition and is part of an adversarial parliamentary system intended to keep the government in check. The Parliament of Canada passes all federal statute laws. It comprises

4171-771: The First Nations to education, government and legal rights. Because Britain still maintained control of Canada's foreign affairs under the British North America Act, 1867, its declaration of war in 1914 automatically brought Canada into the First World War . Volunteers sent to the Western Front later became part of the Canadian Corps , which played a substantial role in the Battle of Vimy Ridge and other major engagements of

4268-411: The Métis' grievances ignited the Red River Rebellion and the creation of the province of Manitoba in July 1870. British Columbia and Vancouver Island (which had been united in 1866) joined the confederation in 1871 on the promise of a transcontinental railway extending to Victoria in the province within 10 years, while Prince Edward Island joined in 1873. In 1898, during the Klondike Gold Rush in

4365-438: The Norse built a small short-lived encampment that was occupied sporadically for perhaps 20 years at L'Anse aux Meadows on the northern tip of Newfoundland . No further European exploration occurred until 1497, when seafarer John Cabot explored and claimed Canada's Atlantic coast in the name of Henry VII of England . In 1534, French explorer Jacques Cartier explored the Gulf of Saint Lawrence where, on July 24, he planted

4462-504: The North China Block (Zhaertai-Bayan Obo Belt). The fragmentation corresponded with widespread anorogenic magmatic activity, forming anorthosite - mangerite - charnockite - granite suites in North America, Baltica, Amazonia, and North China, and continued until the final breakup of the supercontinent at about 1.3–1.2 Ga, marked by the emplacement of the 1.27 Ga Mackenzie and 1.24 Ga Sudbury mafic dyke swarms in North America. Other dyke swarms associated with extensional tectonics and

4559-414: The Northwest Territories, Parliament created the Yukon Territory. Alberta and Saskatchewan became provinces in 1905. Between 1871 and 1896, almost one quarter of the Canadian population emigrated south to the US. To open the West and encourage European immigration, the Government of Canada sponsored the construction of three transcontinental railways (including the Canadian Pacific Railway ), passed

4656-401: The Precambrian time scale on radiometric dating reflects the sparse nature of the fossil record, and Precambrian subdivisions of geologic time roughly reflect major tectonic cycles. It is possible that future revisions to the time scale will reflect more "natural" boundaries based on correlative geologic events. The Mesoproterozoic is presently divided into the Calymmian (1600 to 1400 Mya) and

4753-625: The Rogers and Santosh configuration, whereas the fits of India, East Antarctica, South Africa, and Australia with Laurentia are similar to their corresponding fits in the configuration of Rodinia . This continental configuration is based on the available geological reconstructions of 2.1–1.8 Ga orogens and related Archean cratonic blocks, especially on those reconstructions between South America and west Africa; western Australia and southern Africa; Laurentia and Baltica; Siberia and Laurentia; Laurentia and central Australia; East Antarctica and Laurentia; and North China and India. Of these reconstructions,

4850-399: The Saint Lawrence River. Following the British conquest of New France , this area was known as the British Province of Quebec from 1763 to 1791. In 1791, the area became two British colonies called Upper Canada and Lower Canada . These two colonies were collectively named the Canadas until their union as the British Province of Canada in 1841. Upon Confederation in 1867 , Canada

4947-425: 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

5044-400: 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

5141-411: 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

5238-474: The break-up of Columbia include the Satakunta-Ulvö dyke swarm in Fennoscandia and the Galiwinku dyke swarm in Australia. An area around Georgetown in northern Queensland, Australia , has been suggested to consist of rocks that originally formed part of Nuna 1.7 Ga in what is now northern Canada. In the initial configuration of Rogers and Santosh (2002), South Africa, Madagascar , India, Australia, and attached parts of Antarctica are placed adjacent to

5335-423: 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

5432-520: The complexity of life to come and signified the start of development of true multicellular organisms . Though the biota of the era was once thought to be exclusively microbial, recent finds have shown multicellular life did exist during the Mesoproterozoic. This era was also the high point of the stromatolites before they declined in the Neoproterozoic . The subdivisions of the Mesoproterozoic are arbitrary divisions based on time. They are not geostratigraphic or biostratigraphic units. The decision to base

5529-493: 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

5626-453: 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

5723-432: 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

5820-421: 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

5917-444: 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

6014-563: 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

6111-414: 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

6208-416: 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

6305-488: 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

6402-428: 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

6596-505: The fits of Baltica and Siberia with Laurentia; South America with west Africa; and southern Africa with western Australia are also consistent with paleomagnetic data . A new configuration of Columbia was reconstructed by Guiting Hou (2008) based on the reconstruction of giant radiating dike swarms. Another configuration has been suggested by Chaves and Rezende (2019) supported on available paleomagnetic data and fragments of 1.79-1.75 Ga large igneous provinces . Rogers and Santosh proposed

6693-441: 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,

6790-541: 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

6887-412: 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

6984-521: 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

7081-788: 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

7178-686: 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

7275-744: 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

7372-478: The name Columbia for a hypothetical supercontinent preceding Rodinia. They chose the name because critical evidence for the supercontinent was provided by the relationship between the Columbia region of North America (centered on the state of Washington ) and east India. The naming is not universally accepted. In 1997, P.F. Hoffman proposed the name Nuna (from Inuit "lands bordering the northern oceans") for

7469-634: 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

7566-565: 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

7663-488: 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

7760-819: 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

7857-667: The same time. In South America, a 1.8–1.3 Ga accretionary zone occurs along the western margin of the Amazonia Craton, represented by the Rio Negro, Juruena, and Rondonian Belts. In Australia, 1.8–1.5 Ga accretionary magmatic belts, including the Arunta, Mount Isa, Georgetown, Coen, and Broken Hill Belts, occur surrounding the southern and eastern margins of the North Australia Craton and the eastern margin of

7954-756: 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:

8051-427: The southern edge of Scandinavia . Columbia was assembled along global-scale 2.1–1.8 Ga collisional orogens and contained almost all of Earth 's continental blocks. Some of the events associated with the assembly of Columbia are: Following its final assembly at c. 1.82 Ga, Columbia underwent long-lived (1.82–1.5 Ga), subduction -related growth via accretion at key continental margins, forming at 1.82–1.5 Ga

8148-485: 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

8245-433: The supercontinent was likely completed during global-scale collisional events from 2,100 to 1,800 Ma. Columbia consisted of proto- cratons that made up the cores of the continents of Laurentia , Baltica , Ukrainian Shield , Amazonian Craton , Australia , and possibly Siberia , North China , and Kalaharia as well. The evidence of Columbia's existence is provided by geological and paleomagnetic data. Columbia

8342-506: 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

8439-508: 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

8536-912: The time boundary between the Mesoproterozoic and the subsequent Neoproterozoic . These tectonic events were accompanied by numerous orogenies (episodes of mountain building ) that included the Kibaran orogeny in Africa; the Late Ruker orogeny in Antarctica; the Gothian and Sveconorwegian orogenies in Europe; and the Picuris and Grenville orogenies in North America. The era saw the development of sexual reproduction, which greatly increased

8633-446: 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

8730-481: 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

8827-545: 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

8924-546: 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

9021-425: The western margin of North America, whereas Greenland, Baltica (Northern Europe), and Siberia are positioned adjacent to the northern margin of North America, and South America is placed against West Africa . In the same year (2002), Zhao et al. proposed an alternative configuration of Columbia, in which the fits of Baltica and Siberia with Laurentia and the fit of South America with West Africa are similar to those of

9118-464: 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

9215-615: 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,

9312-696: 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

9409-430: 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
