Manitoba became Canada's fifth province when the area that had been the Red River Settlement was admitted to the confederation in 1870. The present-day province straddles the boundary between the Prairie and Central Canada, and it has both a large agricultural sector and a topography similar to those of the provinces of Saskatchewan and Alberta. It also has a mixed economy, an urban orientation, and a multiethnic character, all of which are more like Ontario than the Prairie West. While other areas of the Canadian West have experienced economic cycles of boom and bust, Manitoba has maintained a steadier pace. Similarly, the province's political and cultural life has largely avoided the extremes that tend to characterize western Canadian society. Area 250,116 square miles (647,797 square km), of which about one-sixth is inland water. Pop. (2001) 1,119,583; (2006) 1,148,401.

To the north and east of the lowland is the geologically ancient Canadian Shield, an area of rocks, forests, and rivers. It covers about three-fifths of the province and is drained by the Nelson (Nelson River) and Churchill rivers into Hudson Bay. The Hudson Bay Lowland extends roughly 100 miles (160 km) inland as a flat plain of tundra and boglike muskeg. Manitoba's Western Upland is on the Saskatchewan border. The Riding, Duck (Duck Mountain), and Porcupine mountains form the Manitoba Escarpment, the highest point of which is Baldy Mountain at 2,727 feet (831 metres). Soil conditions change from south to north. In the fertile zone, south and west of Lake Winnipeg, black soils suitable for farming dominate, although there are occasional large sandy areas. North of this region, lower-quality black soil and gray wooded soils are found. Soil in the shield, generally not suitable for agriculture, is characterized as gray wooded, podzol, and peat.

Manitoba has a moderately dry climate with sharp seasonal temperature changes. Winter temperatures of -40 °F (-40 °C) are not uncommon in any part of the province; summer days of 100 °F (38 °C) are not unusual in the southern regions. Average daily temperatures in Winnipeg range from 9 °F (−13 °C) in January to 80 °F (27 °C) in July. Average lows vary from -9 °F (-23 °C) in January to 57 °F (14 °C) in July. Annual precipitation varies from 14 inches (360 mm) in the north to 22 inches (560 mm) in the southeast, with about two-thirds of it falling between May and September. Snow typically covers the ground from November to April in the south and even longer in the north.

The southern part of the province was once covered by open grasslands, most of which have been converted into farmland. The southern plains are relatively treeless, except for the river valleys, where stands of aspen, oak, willow, and poplar are common. Manitoba's more than 148,000 square miles (383,000 square km) of forest include open parklands of ash, Manitoba maple, elm, and oak in the south, becoming a mixed broad-leaved and coniferous forest to the north and west and a true northern coniferous forest in the higher elevations. Trees in the north include white and black spruce, jack pine, aspen, white birch, and tamarack. The Hudson Bay lowlands have willow and spruce, as well as moss, lichens, and sedges.

Manitoba is home to a number of North American aboriginal (Native American) groups, including the Assiniboin and Ojibwa Indians (First Nations) in the south, the Cree and Chipewyan Indians in the north, and the (aboriginal Arctic people of Canada, called Eskimo in the United States) on the Hudson Bay coast. The aboriginal peoples have occupied the region for thousands of years, although historically there has been considerable population movement. In addition, their numbers were greatly reduced as a result of exposure to European diseases, particularly smallpox. In the early 19th century the Métis (people of mixed Indian and European ancestry, whom the Canadian government granted legal recognition as a native group at the beginning of the 21st century) developed a unique plains culture. The early agricultural Red River Settlement attracted a number of Scottish farmers, and improvements to river and rail transportation led to the rapid growth of European settlement between 1870 and 1900. Most early settlers were from elsewhere in Canada, but Icelanders and German-speaking Mennonites also arrived beginning in the 1870s. After 1896 immigration from eastern Europe began in considerable numbers. Manitoba's population declined during the Great Depression in the 1930s and World War II but grew steadily thereafter, largely through natural increase.

Manitoba is noted for its ethnic diversity. There are many ethnic enclaves within the city of Winnipeg. Notably, the north end of the city retains a strong eastern European character, and the St. Boniface (Saint Boniface) district has one of the largest Francophone communities outside Quebec. Francophones established a number of communities south of Winnipeg; Germans settled in south-central Manitoba; and a sizable Icelandic settlement developed around Gimli, on the shores of Lake Winnipeg. Although more than two-fifths of the current population is of British descent, significant ethnic minorities include Germans, Ukrainians, French, South Asians, Italians, Filipinos, Vietnamese, and Poles. Roman Catholicism and the United Church of Canada are the largest religious denominations, although there are substantial numbers of Anglicans (Anglicanism), Lutherans (Lutheranism), Mennonites (Mennonite), and adherents to Eastern Orthodoxy and the Ukrainian Catholic (Eastern rite (Eastern rite church)) church, plus many smaller groups. Winnipeg's Jewish community is the largest in the Prairie Provinces.

In the south, Manitoba's countryside has an older, more occupied look than those of the other Prairie Provinces. The development of the Red River Settlement in the 19th century gave the early province a distinctly rural character. The rapid occupation of the agricultural lands between 1870 and 1914 and subsequent expansion into the Interlake and northwest areas maintained the rural dominance. During World War II, however, the rural-urban balance tipped. Since then, the depopulation of rural Manitoba has continued apace, and Winnipeg and the province's network of smaller urban centres have grown accordingly. By the turn of the 21st century, nearly three-fourths of the province's population was urban. Over four-fifths of this urban population (and about three-fifths of the total population of the province) resides in metropolitan Winnipeg.

Mainly because Manitoba's economy faltered in the late 20th century, at least by comparison with the economies of other western Canadian provinces, there has been a steady out-migration of young people and professionals to other provinces—especially the Canadian West. Immigration to the province now comes mainly from less-developed countries. Manitoba's population also has become consistently older since the end of World War II. The province's birth rate is slightly higher than the national average. As a result of all of these factors, Manitoba's population was barely growing at the end of the 20th century and the beginning of the 21st.

Forestry is a key factor in northern Manitoba's economy. More than one-fourth of the province's landmass supports valuable timber, although there has been much devastation from forest fires. Manitoba also has a specialized commercial fishing industry, primarily located around the major lakes—Winnipeg, Manitoba, and Winnipegosis.

The province has a range of resources to draw upon, which has allowed it to diversify its economic base. Numerous mineral deposits, including nickel, copper, gold, lead, silver, cadmium, and zinc, make mining a vital part of the economy. Oil and natural gas have been found in the southwest, particularly around Virden, although the fields are relatively small.

Manufacturing has overtaken agriculture as the largest sector of the province's economy. The traditional industries are chiefly involved with resource processing: meatpacking, flour milling, and the production of lumber, pulp, and paper. Distilling, printing, textile manufacture, and nickel and copper ore smelting also remain important. Beginning in the latter part of the 20th century, the economy was supplemented by technology industries, including the manufacture of aeronautical systems, computers, and electrical equipment. Although no single industry dominates the Manitoba economy, many communities are dependent upon only one industry. In general, Manitoba's non-resource-based industries are located in the Winnipeg area, while those based on resource processing are found throughout the province.

The service sector has become the largest single part of Manitoba's economy. Winnipeg, once the commercial centre for western Canada, remains a major financial centre and home to the Winnipeg Commodity Exchange as well as other financial institutions, including insurance companies. The growth of government services also has contributed to the expansion of Manitoba's service sector, as has tourism, which increased steadily at the end of the 20th century, although the province's distance from the centres of North American population remains a drawback. Sportfishing is particularly vital to Manitoba's tourist industry.

Government revenues are derived largely from taxation and federal grants, with a small portion coming from fees and royalties on hunting, fishing, and oil, as well as from other sources.

Because of its central location, Manitoba has long been a focus for transportation activity. The construction of transcontinental railways after Manitoba joined the confederation in 1870 stimulated much development in the region. With the growth of roadways and the decline in passenger train traffic in the late 20th and early 21st centuries, however, many branchlines in outlying areas have been abandoned. The province has an extensive network of major highways running east to west (including the Trans-Canada Highway) and north to south, supplemented by secondary gravel roads. The home of many of Canada's major trucking companies, Manitoba has attempted to exploit the north-south corridor opened by international free-trade agreements.

Winnipeg was once the service headquarters for Trans Canada Airlines, the predecessor of Air Canada, and remains a major hub for air travel. Scheduled flights carry travelers from Manitoba airports to major Canadian centres and the United States, while nonscheduled operators provide service to isolated areas of Manitoba.

The railway port and former military base of Churchill on the shore of Hudson Bay provides a short, direct sea route to Europe. The port is open for only 10 weeks, in late summer, however. Waterborne freight traffic plies Lake Winnipeg in summer, and isolated northern communities and logging and mining camps are served by sled trains and vehicles designed for winter roads.

Manitoba Telecom Services is the principal communications carrier in the province. It began as a government monopoly and was privatized in 1996. It now faces stiff competition from other wireless providers.

Municipalities are incorporated by the province, and local administration is under provincial control. Each municipality is governed by a council headed by a mayor or reeve. Local government districts are governed by provincial administrators. Greater Winnipeg, consolidated into a single administrative unit in 1972, has an elected mayor and council. Provincial policing is handled by the Royal Canadian Mounted Police, except in Winnipeg, which has its own police force.

The people of Manitoba enjoy a relatively high standard of living and access to a wide range of government services. Sanitation and water-delivery systems are part of an extensive public health and safety service. The province oversees medical and hospital insurance programs and provides all Manitobans with free medical insurance. Manitoba has an extensive hospital network, with most specialized services available in Winnipeg or in regional centres. The province also maintains a substantial social welfare infrastructure. Health care and its improvement are among the major political issues in the province.

Elementary, secondary, technical, and vocational schools and universities are a provincial responsibility. Schools are administered by elected boards under the supervision of the Department of Education and are financed by government grants and local taxes. After French-speaking Manitobans fought for their linguistic rights, French was reinstated as a language of instruction in 1970, and immersion programs for non-Francophones became extremely popular, with a doubling of the number of French-speaking Manitobans between the 1970s and '90s.

Manitoba has four universities. The University of Manitoba in Winnipeg is the major academic institution and home to most professional schools. Chiefly an undergraduate institution in arts and sciences and education, the University of Winnipeg is noted for its Institute of Urban Studies. Brandon University is located in the southwestern part of the province. Canadian Mennonite University, an amalgamation of three smaller colleges, was established in 1998 in Winnipeg. Community colleges based in Winnipeg, The Pas, Portage la Prairie, and Brandon operate campuses throughout the province.

Manitoba's diverse population has created a rich and varied cultural life. Ethnic groups—European, Asian, and aboriginal—maintain vigorous attachments to their traditional cultures through schooling, dance, art, music, and crafts. Winnipeg exhibits a variety of cultures; the towns and villages of the southwest have a strong, uniformly British tradition; and ethnic enclaves throughout the province reflect the pattern of initial settlement. Manitoba is noted for its efforts to retain minority languages.

Manitobans have a reputation for supporting cultural agencies. Winnipeg is home to a number of major artistic institutions: the internationally famous Royal Winnipeg Ballet, the Winnipeg Symphony Orchestra, Manitoba Theatre Centre, Prairie Theatre Exchange, the Manitoba Theatre for Young People, Rainbow Stage, Le Cercle Molière, and the Winnipeg Art Gallery. A major centre in downtown Winnipeg houses a concert hall and a planetarium, as well as the Manitoba Museum of Man and Nature.

Manitoba also played an important role in the development of rock music in Canada. In the mid-1960s community clubs in Winnipeg provided crucial venues for a generation of aspiring musicians that included Neil Young (Young, Neil) and the quintessential Canadian rock band the Guess Who.

Important modern writers include Margaret Laurence (Laurence, Margaret) and Gabrielle Roy (Roy, Gabrielle). Painters of note include Ivan Eyre and William Kurelek. Manitoba's most distinguished composer was Sophie-Carmen Eckhardt-Gramatté.

The province maintains a strong sense of its past. The Manitoba Historical Society is the leading agency in that regard. The Archives of Manitoba is a major repository for historical documents, including the collection of the Hudson's Bay Company. There are dozens of historical museums in the towns and cities of the province, as well as a number of historic sites, including the Lower Fort Garry National Historic Site, located just north of Winnipeg, and York Factory National Historic Site on the shores of Hudson Bay.

Manitobans sponsor and support an exceptional array of community and cultural festivals. Among the more important are the Winnipeg Folk Festival; Folklorama, also in Winnipeg; Gimli Icelandic Festival; the National Ukrainian Festival at Dauphin; the Festival du Voyageur in St. Boniface; and the Northern Manitoba Trappers' Festival at The Pas.

Professional sports franchises include the Winnipeg Blue Bombers of the Canadian (gridiron) Football League and a minor league baseball and hockey team. Curling is an important winter sport. In addition to hockey, other major participant sports include baseball, football (soccer), cross-country skiing, fishing, and hunting. Manitoba has one national park, Riding Mountain, and numerous provincial parks.

Manitoba is served by a number of daily and weekly newspapers, of which the most important are the Winnipeg Free Press and the Brandon Sun. There is a small but lively publishing industry centred in Winnipeg.

Aboriginal (Indian 【First Nations】 and Inuit) peoples, who had lived in the Manitoba region for thousands of years, first came in contact with Europeans through the fur trade. Explorers searching for the Northwest Passage reached Hudson Bay in 1610, when Henry Hudson (Hudson, Henry) navigated the east side of the bay to which he gave his name. He was followed by a number of adventurers, including Thomas Button (Button, Sir Thomas) (1612), Jens Munk (1619), and Luke Fox and Thomas James (1631). As a result of the opening of the fur trade in Hudson Bay by French Canadian adventurers Pierre Radisson (Radisson, Pierre-Esprit) and Médard Chouart des Grosseilliers, the Hudson's Bay Company was incorporated in England in 1670 and granted a monopoly over the fur trade in an area designated as Rupert's Land. The Hudson's Bay Company established a number of posts along the bay. The company faced tremendous competition from French traders, who, led by Pierre Gaultier de Varennes et de la Vérendrye (La Vérendrye, Pierre Gaultier de Varennes, et de), reached the Red River in the early 1730s and established a series of posts in the area, including Fort Rouge on the present site of Winnipeg. The French forced the Hudson's Bay Company to expand inland, but the British traders were unable to compete successfully with other traders based in Montreal who eventually organized as the North West Company. That company's agents, known as Nor'westers, came overland into the region and wintered with the aboriginal peoples to facilitate fur trading with them. The agents also worked closely with the Métis and resisted the British company's attempts to establish an agricultural colony at Red River. Several decades of intense competition between the British and French Canadian traders ensued. The bitter, often violent competition culminated in the Seven Oaks Massacre of 1816. Increasing violence and declining profits forced the two firms to merge into the Hudson's Bay Company in 1821.

The successful settlement of the western United States in the 19th century encouraged expansionists in Central Canada to look to the western regions of British North America as Canada's natural hinterland. The agricultural potential of the vast prairie lands west of Red River was documented by two scientific expeditions in 1857: the Palliser Expedition, commissioned by the British government and led by John Palliser, and the (Henry Youle) Hind expedition, authorized by the government of Canada. Negotiations between the Hudson's Bay Company, the British government, and the government of the new Dominion of Canada resulted in an agreement in 1869 to transfer Rupert's Land to Canada. In 1870, under the Manitoba Act, the territory joined the confederation as a province; the remaining lands were designated the Northwest Territories.

The federal government encouraged western settlement by providing land to would-be settlers. There was an initial rush to the new province, but the absence of a rail connection to markets reduced the attractiveness of the region. Construction of the Canadian Pacific Railway had reached Manitoba by the early 1880s; however, settlement was delayed by a Métis uprising in 1885 and further slowed by the continued availability of homestead lands in the United States. Nevertheless, some settlers did come during this period, among them Ontario farmers, Mennonite immigrants, and Icelandic peoples. At the turn of the century, immigration to Manitoba boomed, fueled by massive government advertising, social conditions in Europe, and the decline in available land in the United States.

The immigration boom ushered in an era of prosperity and growth. Winnipeg grew rapidly, becoming the major urban centre for western Canada and earning the nickname “Chicago of the North.” Manitoba farmers, aided by reduced freight rates, higher world prices for wheat, and improved strains of grain seed, enjoyed unprecedented prosperity. Manitoba's economy was transformed during the early part of the century. A strong agricultural sector, diversified among wheat and other grains, livestock, and market gardening, provided the basis for a rapid increase in the commercial and industrial economy, especially around Winnipeg. Manitoba's boundaries expanded westward in 1881, eastward in 1884, and northward in 1912, mainly at the expense of the Northwest Territories.

The economic boom ended just before World War I, ushering in a depression that lasted through the first years of the conflict. Labour unrest over wages and working conditions arose during the war and peaked afterward with the Winnipeg General Strike of 1919. The province was severely affected by the Great Depression of the 1930s, although the problem was more one of prices than of production in the agricultural sector. Nonpartisan or coalition governments ruled the province from 1922 to 1958, when Dufferin Roblin led the Progressive Conservatives (Progressive Conservative Party of Canada) into office. The return to prosperity during World War II was matched by a resolve to diversify the province's economic base. The provincial government gained control of natural resources in the 1930s and began to encourage northern development, particularly of mining and lumbering. Government involvement in the economy peaked during the administrations of the New Democratic Party (NDP) from 1969 to 1977 and 1981 to 1986, with major investments in infrastructure and some controversial experiments in direct ownership.

Indicators of the province's future in the 21st century are mixed. On one hand, Manitoba's economy is growing stronger and more diversified. On the other hand, the province's relatively harsh climate is not particularly attractive to new immigrants, and it has suffered from much out-migration.
