Saskatchewan in the context of Williston Basin

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 Wisconsin glaciation, also called the Wisconsin glacial episode, was the most recent glacial period of the North American ice sheet complex, peaking more than 20,000 years ago. This advance included the Cordilleran Ice Sheet, which nucleated in the northern North American Cordillera; the Innuitian ice sheet, which extended across the Canadian Arctic Archipelago; the Greenland ice sheet; and the massive Laurentide Ice Sheet, which covered the high latitudes of central and eastern North America. This advance was synchronous with global glaciation during the last glacial period, including the North American alpine glacier advance, known as the Pinedale glaciation. The Wisconsin glaciation extended from about 75,000 to 11,000 years ago, between the Sangamonian Stage and the current interglacial, the Holocene. The maximum ice extent occurred about 25,000–21,000 years ago during the last glacial maximum, also known as the Late Wisconsin in North America.

This glaciation radically altered the geography north of the Ohio River, creating the Great Lakes. At the height of the Wisconsin Episode glaciation, the ice sheet covered most of Canada, the Upper Midwest, and New England, as well as parts of Idaho, Montana, and Washington. On Kelleys Island in Lake Erie, northern New Jersey and in New York City's Central Park, the grooves left in rock by these glaciers can be easily observed. In southwestern Saskatchewan and southeastern Alberta a suture zone between the Laurentide and Cordilleran ice sheets formed the Cypress Hills, North America's northernmost point that remained south of the continental ice sheets. During much of the glaciation, sea level was low enough to permit land animals, including humans, to occupy Beringia (the Bering Land Bridge) and move between North America and Siberia. As the glaciers retreated, glacial lakes were breached in great glacial lake outburst floods such as the Kankakee Torrent, which reshaped the landscape south of modern Chicago as far as the Ohio and Mississippi Rivers.

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 US 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 (including its waters), 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 (Alberta and Saskatchewan) while the other eleven all directly border one of three oceans.

Canada is 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. Much of the Canadian Arctic is covered by ice and permafrost. Canada has the longest coastline in the world, with a total length of 243,042 kilometres (151,019 mi); additionally, its border with the United States is the world's longest land border, stretching 8,891 kilometres (5,525 mi). Three of Canada's Arctic islands, Baffin Island, Victoria Island and Ellesmere Island, are among the ten largest in the world.

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.

The Northern Saskatchewan Administration District (NSAD) is the unincorporated area of Northern Saskatchewan, Canada. It encompasses approximately half of Saskatchewan's land mass. Despite its extent, the majority of Saskatchewanians live in the southern half of the province, while the majority of northern Saskatchewanians live in incorporated municipalities outside the NSAD's jurisdiction. The area is co-extensive with Division No. 18, Saskatchewan, one of Statistics Canada's census divisions in the province for its 2016 census.

The census division is the largest in the province in terms of area at 269,996.55 square kilometres (104,246.25 sq mi), representing 46 per cent of the province's entire area of 588,239.21 square kilometres (227,120.43 sq mi).

Montana (/mɒnˈtænə/ mon-TAN-ə) is a landlocked state in the Mountain West subregion of the Western United States. It is bordered by Idaho to the west, North Dakota to the east, South Dakota to the southeast, Wyoming to the south, and the Canadian provinces of Alberta, British Columbia, and Saskatchewan to the north. It is the fourth-largest state by area, but the eighth-least populous state and the third-least densely populated state. Its capital is Helena, while the most populous city is Billings. The western half of the state contains numerous mountain ranges, while the eastern half is characterized by western prairie terrain and badlands, with smaller mountain ranges found throughout the state.

Most of Montana first came under American sovereignty with the Louisiana Purchase from France in 1803 and was explored by the Lewis and Clark Expedition shortly thereafter. Fur trappers followed and were the main economic activity in the area until gold was discovered in 1852. The ensuing gold rush, along with the passage of the Homestead Acts in 1862, brought large numbers of American settlers to Montana. Rapid population growth and development culminated in statehood on November 8, 1889. Mining, particularly around Butte and Helena, would remain the state's main economic engine through the mid-20th century.

Prairies are ecosystems considered part of the temperate grasslands, savannas, and shrublands biome by ecologists, based on similar temperate climates, moderate rainfall, and a composition of grasses, herbs, and shrubs, rather than trees, as the dominant vegetation type. Temperate grassland regions include the Pampas of Argentina, Brazil and Uruguay, and the steppe of Romania, Ukraine, Russia, and Kazakhstan. Lands typically referred to as "prairie" (a French loan word) tend to be in North America. The term encompasses the lower and mid-latitude of the area referred to as the Interior Plains of Canada, the United States, and Mexico. It includes all of the Great Plains as well as the wetter, hillier land to the east. From west to east, generally the drier expanse of shortgrass prairie gives way to mixed grass prairie and ultimately the richer and wetter soils of the tallgrass prairie.

In the U.S., the area is constituted by most or all of the states, from north to south, of North Dakota, South Dakota, Nebraska, Kansas, and Oklahoma, and sizable parts of the states of Montana, Wyoming, Colorado, New Mexico, Texas in the west, and to the east, Minnesota, Wisconsin, Iowa, Missouri, Illinois, and Indiana. The Palouse of Washington and the Central Valley of California are also prairies. The Canadian Prairies occupy vast areas of Manitoba, Saskatchewan, and Alberta. Prairies may contain various lush flora and fauna, often contain rich soil maintained by biodiversity, with a temperate climate and a varied view.

The four corners is a quadripoint near 60°N 102°W / 60°N 102°W / 60; -102 (Four corners (Canada) approximately) where four Canadian provinces or territories meet. These are the provinces of Manitoba and Saskatchewan and the territories of the Northwest Territories and Nunavut. It came into being with the creation of Nunavut on April 1, 1999.

Alberta is a province in Canada. It is a part of Western Canada and is one of the three prairie provinces. Alberta is bordered by British Columbia to its west, Saskatchewan to its east, the Northwest Territories to its north, and the U.S. state of Montana to its south. Alberta and Saskatchewan are the only two landlocked Canadian provinces. The eastern part of the province is occupied by the Great Plains, while the western part borders the Rocky Mountains. The province has a predominantly continental climate, but seasonal temperatures tend to swing rapidly because it is so arid. Those swings are less pronounced in western Alberta because of its occasional Chinook winds.Alberta is the fourth largest province by area, at 661,848 square kilometres (255,541 square miles), and the fourth most populous, with 4,262,635 residents. Alberta's capital is Edmonton; its largest city is Calgary. The two cities are Alberta's largest census metropolitan areas. More than half of Albertans live in Edmonton or Calgary, which encourages a continuing rivalry between the two cities. English is the province's official language. In 2016, 76.0% of Albertans were anglophone, 1.8% were francophone and 22.2% were allophone.

Alberta's economy is advanced, open, market-based, and characterized by a highly educated workforce, strong institutions and property rights, and sophisticated financial markets. The service sector employs 80% of Albertans, in fields like healthcare, education, professional services, retail, tourism and financial services. The industrial base includes manufacturing, construction, and agriculture (10%, 5%, and 2% of employment respectively), while the knowledge economy includes about 3000 tech companies employing an estimated 60,000 people, mainly in Calgary and Edmonton. The energy sector employs 5% of Albertans but significantly impacts exports and GDP. Alberta's exports, primarily US-bound, consist of 70% oil and gas, 13% food products, and 12% industrial products. Oil and gas are culturally influential, having shaped politics, generated "striking it rich" narratives, and created boom-and-bust cycles. In 2023, Alberta's output was $350 billion, 15% of Canada's GDP.

North Dakota ( /dəˈkoʊtə/ də-KOH-tə) is a U.S. state in the Upper Midwest, named after the indigenous Dakota and Sioux peoples. It is bordered by the Canadian provinces of Saskatchewan and Manitoba to the north and by the U.S. states of Minnesota to the east, South Dakota to the south, and Montana to the west. North Dakota is part of the Great Plains region, characterized by broad prairies, steppe, temperate savanna, badlands, and farmland. North Dakota is the 19th-largest state by area, but with a population of just under 800,000, the fourth-least populous and fourth-least densely populated. The state capital is Bismarck and the most populous city is Fargo, which accounts for nearly a fifth of the state's population; both cities are among the fastest-growing in the U.S., although half of North Dakotans live in rural areas.

What is now North Dakota was inhabited for thousands of years by various Native American tribes, including the Mandan, Hidatsa, and Arikara along the Missouri River; the Ojibwe and Cree in the northeast; and several Sioux groups (the Nakota, Dakota, and Lakota) in the rest of the state. European explorers and traders first arrived in the early 18th century, mostly in pursuit of furs.

The Cypress Hills are a geographical region of hills in southwestern Saskatchewan and southeastern Alberta, Canada. The hills are part of the Missouri Coteau upland. The hills cover an area of approximately 2,500 km (970 sq mi). About 400 km (150 sq mi) or 16% of this area is an interprovincial park.

The highest point in the Cypress Hills is at Head of the Mountain in Alberta at 1,466 m (4,810 ft). The highest point in Saskatchewan is an unnamed point (49°33′06″N 109°59′14″W / 49.55167°N 109.98722°W / 49.55167; -109.98722) at 1,392 m (4,567 ft).

Rupert's Land (French: Terre de Rupert), or Prince Rupert's Land (French: Terre du Prince Rupert), was a territory in British America (British North America after 1783) based on the Hudson Bay drainage basin. The right to "sole trade and commerce" over Rupert's Land was granted to the Hudson's Bay Company (HBC), based at York Factory, effectively giving that company a commercial monopoly over the area. The territory operated for 200 years from 1670 to 1870. Its namesake was Prince Rupert of the Rhine, who was a nephew of King Charles I and the first governor of the HBC. In December 1821, the HBC monopoly was extended from Rupert's Land to the Pacific coast.

The areas formerly belonging to Rupert's Land lie mostly within what is today Canada, and included the whole of Manitoba, most of Saskatchewan, southern Alberta, southern Nunavut, and northern parts of Ontario and Quebec. Additionally, it also extended into areas that would eventually become parts of Minnesota, North Dakota, and Montana. The southern border west of Lake of the Woods to the Rocky Mountains was the drainage divide between the Mississippi and Red/Saskatchewan watersheds until the Anglo-American Convention of 1818 substituted the 49th parallel.

Western Canada, also referred to as the Western provinces, Canadian West, or Western provinces of Canada, and commonly known within Canada as the West, is a Canadian region that includes the four western provinces just north of the Canada–United States border namely (from west to east) British Columbia, Alberta, Saskatchewan and Manitoba. The people of the region are often referred to as "Western Canadians" or "Westerners", and though diverse from province to province are largely seen as being collectively distinct from other Canadians along cultural, linguistic, socioeconomic, geographic and political lines. They account for approximately 32% of Canada's total population.

The region is further subdivided geographically and culturally between British Columbia, which is mostly on the western side of the Canadian Rockies and often referred to as the "west coast", and the "Prairie Provinces" (commonly known as "the Prairies"), which include those provinces on the eastern side of the Rockies yet west of Ontario - Alberta, Saskatchewan and Manitoba. Alberta and British Columbia are also sometimes subcategorized together, either as the "Rockie Provinces" or "mountain provinces" owing to both hosting large swathes of the mountain range, or due to shared socioeconomic factors such as their highly urbanized populations (three of Canada's five largest cities are Calgary, Edmonton, and Vancouver) and significant interprovincial mobility between the two. Alberta and Saskatchewan, having once been united as a single territory, are also sometimes subcategorized together due to shared political and economic histories, as well as similar historic migratory patterns from Eastern Europe.

Ojibwe (/oʊˈdʒɪbweɪ/ oh-JIB-way), also known as Ojibwa (/oʊˈdʒɪbwə/ oh-JIB-wə), Ojibway, Otchipwe, Ojibwemowin, or Anishinaabemowin, is an indigenous language of North America of the Algonquian language family. The language is characterized by a series of dialects that have local names and frequently local writing systems. There is no single dialect that is considered the most prestigious or most prominent, and no standard writing system that covers all dialects.

Dialects of Ojibwemowin are spoken in Canada, from southwestern Quebec, through Ontario, Manitoba and parts of Saskatchewan, with outlying communities in Alberta; and in the United States, from Michigan to Wisconsin and Minnesota, with a number of communities in North Dakota and Montana, as well as groups that were removed to Kansas and Oklahoma during the Indian Removal period. While there is some variation in the classification of its dialects, at least the following are recognized, from east to west: Algonquin, Eastern Ojibwe, Ottawa (Odawa), Western Ojibwe (Saulteaux), Oji-Cree (Severn Ojibwe), Northwestern Ojibwe, and Southwestern Ojibwe (Chippewa). Based upon contemporary field research, J. R. Valentine also recognizes several other dialects: Berens Ojibwe in northwestern Ontario, which he distinguishes from Northwestern Ojibwe; North of (Lake) Superior; and Nipissing. The latter two cover approximately the same territory as Central Ojibwa, which he does not recognize.

Statistics Canada conducts a national census of population and census of agriculture every five years and releases the data with a two-year lag.

The Census of Population provides demographic and statistical data that is used to plan public services such as health care, education, and transportation; determine federal transfer payments; and determine the number of Members of Parliament for each province and territory. The Census of Population is the primary source of sociodemographic data for specific population groups, such as lone-parent families, Indigenous peoples, immigrants, seniors and language groups. Data from the census is also used to assess the economic state of the country, including the economic conditions of immigrants over time, and labour market activity of communities and specific populations. Census data are also leveraged to develop socioeconomic status indicators in support of analysis of various impacts on education achievement and outcomes. At a sub-national level, two provinces (Alberta and Saskatchewan) and two territories (Nunavut and Yukon) have legislation that allows local governments to conduct their own municipal censuses.

A multitude of languages have always been spoken in Canada. Prior to Confederation, the territories that would become Canada were home to over 70 distinct languages across 12 or so language families. Today, a majority of those indigenous languages are still spoken; however, most are endangered and only about 0.6% of the Canadian population report an indigenous language as their mother tongue. Since the establishment of the Canadian state, English and French have been the co-official languages and are, by far, the most-spoken languages in the country.

According to the 2021 census, English and French are the mother tongues of 56.6% and 20.2% of Canadians respectively. According to the 2016 census, a total of 86.2% of Canadians could conduct a conversation in English, while 29.8% could conduct a conversation in French. Under the Official Languages Act of 1969, both English and French have official status throughout Canada in respect of federal government services and most courts. All federal legislation is enacted bilingually. Provincially, only in New Brunswick are both English and French official to the same extent. French is Quebec's official language, although legislation is enacted in both French and English and court proceedings may be conducted in either language. English is the official language of Ontario, Manitoba and Alberta, but government services are available in French in many regions of each, particularly in regions and cities where Francophones form the majority. Legislation is enacted in both languages and courts conduct cases in both. In 2022, Nova Scotia recognized Mi'kmawi'simk as the first language of the province, and maintains two provincial language secretariats: the Office of Acadian Affairs and Francophonie (French language) and the Office of Gaelic Affairs (Canadian Gaelic). The remaining provinces (British Columbia, Saskatchewan, Prince Edward Island, and Newfoundland and Labrador) do not have an official provincial language per se but government is primarily English-speaking. Territorially, both the Northwest Territories and Nunavut have official indigenous languages alongside French and English: Inuktut (Inuktitut and Inuinnaqtun) in Nunavut and, in the NWT, nine others (Cree, Dënësųłıné, Dene Yatıé/Zhatıé, Gwich’in, Inuinnaqtun, Inuktitut, Inuvialuktun, Sahtúgot’įné Yatı̨́ / Shíhgot’įne Yatı̨́ / K’ashógot’įne Goxedǝ́, and Tłįchǫ Yatıì).

The Canadian Prairies (usually referred to as simply the Prairies in Canada) is a region in Western Canada. It includes the Canadian portion of the Great Plains and the Prairie provinces, namely Alberta, Saskatchewan, and Manitoba. These provinces are partially covered by grasslands, plains, and lowlands, mostly in the southern regions. The northernmost reaches of the Canadian Prairies are less dense in population, marked by forests and more variable topography. If the region is defined to include areas only covered by prairie land, the corresponding region is known as the Interior Plains. Physical or ecological aspects of the Canadian Prairies extend to northeastern British Columbia, but that area is not included in the political use of the term.

The prairies in Canada are a biome of temperate grassland and shrubland within the prairie ecoregion of Canada. This ecoregion consists of northern mixed grasslands in Alberta, Saskatchewan, and southern Manitoba, as well as northern short grasslands in southeastern Alberta and southwestern Saskatchewan. The Prairies Ecozone of Canada includes the northern tall grasslands in southern Manitoba and Aspen parkland, which covers central Alberta, central Saskatchewan, and southern Manitoba. The Prairie starts from north of Edmonton and it covers the three provinces in a southward-slanting line east to the Manitoba–Minnesota border. Alberta has the most land classified as prairie, while Manitoba has the least, as the boreal forest begins more southerly in Manitoba than in Alberta.

Sage-grouse are grouse belonging to the bird genus Centrocercus. The genus includes two species: the Gunnison grouse (Centrocercus minimus) and the greater sage-grouse (Centrocercus urophasianus). These birds are distributed throughout large portions of the north-central and Western United States, as well as the Canadian provinces of Alberta and Saskatchewan. The International Union for Conservation of Nature classified theC. minimus species as endangered in 2020 and C. urophasianus as near threatened in 2016.

The wood bison (Bison bison athabascae) or mountain bison (often called the wood buffalo or mountain buffalo), and Athabaskan bison (or Athabaskan buffalo), is a distinct northern subspecies or ecotype of the American bison. Its original range included much of the boreal forest regions of Alaska, Yukon, western Northwest Territories, northeastern British Columbia, northern Alberta, and northwestern Saskatchewan. An attempt is ongoing to reintroduce them into the wilderness of Eurasia by Sakha Republic of Russia.

Pure-bred wood bison were believed to be extinct after the late 1920s as a result of intermixing with plains bison in Wood Buffalo National Park, then believed to be their last refuge. A nearly pure herd was found in 1957 in an isolated portion of the park. Herds called the Firebag River and Ronald Lake herds potentially have had no contact with the Wood Buffalo National Park herd.
