Ontario is one of the ten provinces of Canada, located in east-central Canada. It is Canada's most populous province by a large margin, accounting for nearly 40% of all Canadians, and is the second largest province in total area. Ontario is fourth largest in total area when the territories of the Northwest Territories and Nunavut are included. It is home to the nation's capital city, Ottawa, and the nation's most populous city, Toronto.
Ontario is bordered by the province of Manitoba to the west, Hudson Bay and James Bay to the north, and Quebec to the east, and to the south by the U.S. states of Minnesota, Michigan, New York, Ohio and Pennsylvania. All but a small part of Ontario's border with the United States follows inland waterways: from the west at Lake of the Woods, eastward along the major rivers and lakes of the Great Lakes/Saint Lawrence River drainage system. These are the Rainy River, the Pigeon River, Lake Superior, the St. Marys River, Lake Huron, the St. Clair River, Lake St. Clair, the Detroit River, Lake Erie, the Niagara River, Lake Ontario and along the St. Lawrence River from Kingston, Ontario, to the Quebec boundary just east of Cornwall, Ontario.
Ontario is sometimes conceptually divided into two regions, Northern Ontario and Southern Ontario. The great majority of Ontario's population and its arable land is located in the south. In contrast, the larger, northern part of Ontario is sparsely populated.
Land was not legally subdivided into administrative units until a treaty had been concluded with the native peoples ceding the land. In 1788, while part of the Province of Quebec (1763–1791), southern Ontario was divided into four districts: Hesse, Lunenburg, Mecklenburg, and Nassau.
In 1792, the four districts were renamed: Hesse became the Western District, Lunenburg became the Eastern District, Mecklenburg became the Midland District, and Nassau became the Home District. Counties were created within the districts.
By 1838, there were twenty districts: Bathurst, Brock, Colbourne, Dalhousie, Eastern, Gore, Home, Huron, Johnstown, London, Midland, Newcastle, Niagara, Ottawa, Prince Edward, Simcoe, Talbot, Victoria, Wellington, and Western.
In 1849, the districts of southern Ontario were abolished by the Province of Canada, and county governments took over certain municipal responsibilities. The Province of Canada also began creating districts in sparsely populated Northern Ontario with the establishment of Algoma District and Nipissing District in 1858.
The borders of Ontario, its new name in 1867, were provisionally expanded north and west. When the Province of Canada was formed, its borders were not entirely clear, and Ontario claimed eventually to reach all the way to the Rocky Mountains and Arctic Ocean. With Canada's acquisition of Rupert's Land, Ontario was interested in clearly defining its borders, especially since some of the new areas in which it was interested were rapidly growing. After the federal government asked Ontario to pay for construction in the new disputed area, the province asked for an elaboration on its limits, and its boundary was moved north to the 51st parallel north.
The northern and western boundaries of Ontario were in dispute after Canadian Confederation. Ontario's right to Northwestern Ontario was determined by the Judicial Committee of the Privy Council in 1884 and confirmed by the Canada (Ontario Boundary) Act, 1889 of the Parliament of the United Kingdom. By 1899, there were seven northern districts: Algoma, Manitoulin, Muskoka, Nipissing, Parry Sound, Rainy River, and Thunder Bay. Four more northern districts were created between 1907 and 1912: Cochrane, Kenora, Sudbury and Timiskaming.
Before the arrival of the Europeans, the region was inhabited by Algonquian (Ojibwa, Cree and Algonquin) in the northern/western portions, and Iroquois and Wyandot (Huron) tribes more in the south/east. During the 17th century, the Algonquians and Hurons fought the Beaver Wars against the Iroquois. The French explorer Étienne Brûlé explored part of the area in 1610-12. The English explorer Henry Hudson sailed into Hudson Bay in 1611 and claimed the area for England.
Samuel de Champlain reached Lake Huron in 1615, and French missionaries began to establish posts along the Great Lakes. French settlement was hampered by their hostilities with the Iroquois, who allied themselves with the British. From 1634 to 1640, Hurons were devastated by European infectious diseases, such as measles and smallpox, to which they had no immunity.
The British established trading posts on Hudson Bay in the late 17th century and began a struggle for domination of Ontario. The 1763 Treaty of Paris ended the Seven Years' War by awarding nearly all of France's North American possessions (New France) to Britain. The region was annexed to Quebec in 1774. From 1783 to 1796, the Kingdom of Great Britain granted United Empire Loyalists leaving the United States following the American Revolution land and other items with which to rebuild their lives.
This measure substantially increased the population of Canada west of the St. Lawrence-Ottawa River confluence during this period, a fact recognized by the Constitutional Act of 1791, which split Quebec into the Canadas: Upper Canada southwest of the St. Lawrence-Ottawa River confluence, and Lower Canada east of it. John Graves Simcoe was appointed Upper Canada's first Lieutenant governor in 1793.
American troops in the War of 1812 invaded Upper Canada across the Niagara River and the Detroit River, but were defeated and pushed back by British regulars, Canadian fencibles and militias, and First Nations warriors. However, eventually the Americans gained control of Lake Erie and Lake Ontario. During the Battle of York in 1813, American troops occupied the Town of York. The Americans looted the town and burned the Parliament Buildings during the brief occupation.
After the War of 1812, relative stability allowed for increasing numbers of immigrants to arrive from Europe rather than from the United States. As was the case in the previous decades, this deliberate immigration shift was encouraged by the colonial leaders. Despite affordable and often free land, many arriving newcomers, mostly from Britain and Ireland, found frontier life with the harsh climate difficult, and some of those with the means eventually returned home or went south. However, population growth far exceeded emigration in the decades that followed. It was a mostly agrarian-based society, but canal projects and a new network of plank roads spurred greater trade within the colony and with the United States, thereby improving previously damaged relations over time.
Meanwhile, Ontario's numerous waterways aided travel and transportation into the interior and supplied water power for development. As the population increased, so did the industries and transportation networks, which in turn led to further development. By the end of the century, Ontario vied with Quebec as the nation's leader in terms of growth in population, industry, arts and communications.
Many in the colony however, began to chafe against the aristocratic Family Compact who governed while benefiting economically from the region's resources, and who did not allow elected bodies the power to effect change (much as the Château Clique ruled Lower Canada). This resentment spurred republican ideals and sowed the seeds for early Canadian nationalism. Accordingly, rebellion in favour of responsible government rose in both regions; Louis-Joseph Papineau led the Lower Canada Rebellion and William Lyon Mackenzie led the Upper Canada Rebellion.
Although both rebellions were put down in short order, the British government sent Lord Durham to investigate the causes of the unrest. He recommended that self-government be granted and that Lower and Upper Canada be re-joined in an attempt to assimilate the French Canadians. Accordingly, the two colonies were merged into the Province of Canada by the Act of Union 1840, with the capital at Kingston, and Upper Canada becoming known as Canada West. Parliamentary self-government was granted in 1848. There were heavy waves of immigration in the 1840s, and the population of Canada West more than doubled by 1851 over the previous decade. As a result, for the first time the English-speaking population of Canada West surpassed the French-speaking population of Canada East, tilting the representative balance of power.
An economic boom in the 1850s coincided with railway expansion across the province, further increasing the economic strength of Central Canada. With the repeal of the Corn Laws and a reciprocity agreement in place with United States, various industries such as timber, mining, farming and alcohol distilling benefited tremendously.
A political stalemate between the French- and English-speaking legislators, as well as fear of aggression from the United States during and immediately after the American Civil War, led the political elite to hold a series of conferences in the 1860s to effect a broader federal union of all British North American colonies. The British North America Act took effect on July 1, 1867, establishing the Dominion of Canada, initially with four provinces: Nova Scotia, New Brunswick, Quebec and Ontario. The Province of Canada was divided into Ontario and Quebec so that each linguistic group would have its own province. Both Quebec and Ontario were required by section 93 of the British North America Act to safeguard existing educational rights and privileges of Protestant and the Catholic minority. Thus, separate Catholic schools and school boards were permitted in Ontario. However, neither province had a constitutional requirement to protect its French- or English-speaking minority. Toronto was formally established as Ontario's provincial capital.
Once constituted as a province, Ontario proceeded to assert its economic and legislative power. In 1872, the lawyer Oliver Mowat became Premier of Ontario and remained as premier until 1896. He fought for provincial rights, weakening the power of the federal government in provincial matters, usually through well-argued appeals to the Judicial Committee of the Privy Council. His battles with the federal government greatly decentralized Canada, giving the provinces far more power than John A. Macdonald had intended. He consolidated and expanded Ontario's educational and provincial institutions, created districts in Northern Ontario, and fought to ensure that those parts of Northwestern Ontario not historically part of Upper Canada (the vast areas north and west of the Lake Superior-Hudson Bay watershed, known as the District of Keewatin) would become part of Ontario, a victory embodied in the Canada (Ontario Boundary) Act, 1889. He also presided over the emergence of the province into the economic powerhouse of Canada. Mowat was the creator of what is often called Empire Ontario.
Beginning with Sir John A. Macdonald's National Policy (1879) and the construction of the Canadian Pacific Railway (1875–1885) through Northern Ontario and the Canadian Prairies to British Columbia, Ontario manufacturing and industry flourished. However, population increase slowed after a large recession hit the province in 1893, thus slowing growth drastically but for only a few years. Many newly arrived immigrants and others moved west along the railway to the Prairie Provinces and British Columbia, sparsely settling Northern Ontario.
Mineral exploitation accelerated in the late 19th century, leading to the rise of important mining centres in the northeast, such as Sudbury, Cobalt and Timmins. The province harnessed its water power to generate hydro-electric power and created the state-controlled Hydro-Electric Power Commission of Ontario, later Ontario Hydro. The availability of cheap electric power further facilitated the development of industry. The Ford Motor Company of Canada was established in 1904. General Motors Canada was formed in 1918. The motor vehicle industry would go on to become the most lucrative industry for the Ontario economy during the 20th century.
In July 1912, the Conservative government of Sir James Whitney issued Regulation 17 which severely limited the availability of French-language schooling to the province's French-speaking minority. French Canadians reacted with outrage, journalist Henri Bourassa denouncing the "Prussians of Ontario". The regulation was eventually repealed in 1927.
Influenced by events in the United States, the government of Sir William Hearst introduced prohibition of alcoholic drinks in 1916 with the passing of the Ontario Temperance Act. However, residents could distill and retain their own personal supply, and liquor producers could continue distillation and export for sale, allowing this already sizable industry to strengthen further. Ontario became a hotbed for the illegal smuggling of liquor and the biggest supplier into the United States, which was under complete prohibition. Prohibition in Ontario came to an end in 1927 with the establishment of the Liquor Control Board of Ontario under the government of Howard Ferguson. The sale and consumption of liquor, wine, and beer are still controlled by some of the most extreme laws in North America to ensure that strict community standards and revenue generation from the alcohol retail monopoly are upheld. In April 2007, Ontario Member of Provincial Parliament Kim Craitor suggested that local brewers should be able to sell their beer in local corner stores; however, the motion was quickly rejected by Premier Dalton McGuinty.
The post-World War II period was one of exceptional prosperity and growth. Ontario has been the recipients of most immigration to Canada, largely immigrants from war-torn Europe in the 1950s and 1960s and following changes in federal immigration law, a massive influx of non-Europeans since the 1970s. From a largely ethnically British province, Ontario has rapidly become culturally very diverse.
The nationalist movement in Quebec, particularly after the election of the Parti Québécois in 1976, contributed to driving many businesses and English-speaking people out of Quebec to Ontario, and as a result Toronto surpassed Montreal as the largest city and economic centre of Canada. Depressed economic conditions in the Maritime Provinces have also resulted in de-population of those provinces in the 20th century, with heavy migration into Ontario.
