Indigenous habitation (pre–1610) Paleo-Indians were the first people to settle on the lands of Ontario, about 11,000 years ago, after crossing the
Bering land bridge from Asia to North America between 25,000 and 50,000 years ago. During the
Archaic period, which lasted from 8000 to 1000
BC, the population slowly increased, with a generally egalitarian
hunter-gatherer society and a warmer climate. Trading routes also began emerging along the
St. Lawrence River and around the
Great Lakes. Hunting and gathering remained predominant throughout the early
Woodland period, and social structures and trade continued to develop. Around 500
AD, corn cultivation began, later expanding to include
beans and
squash around 1100 AD. Increased agriculture enabled more permanent, fortified, and significantly larger settlements. In southern Ontario during the 1400s, the population of some villages numbered in the thousands, with
longhouses that could house over a hundred people. Around this time, large-scale warfare began in southern Ontario, leading to the emergence of
Iroquoian groups, including the
Neutral Confederacy,
Erie and
Wendat (Huron). Groups in northern Ontario were primarily
Algonquian and included the
Ojibwe, who traded with the Iroquois. Many ethnocultural groups emerged and came to exist on the lands of Ontario: the
Algonquins,
Mississaugas,
Ojibway,
Cree,
Odawa,
Pottowatomi, and
Iroquois.
Pays d'en Haut (1610–1763) In 1608,
Samuel de Champlain established France's first colonial settlement in
New France, the
Habitation de Québec (now
Quebec City). French explorers continued to travel west, establishing new villages along the coasts of the Saint Lawrence River. French explorers, the first of which was
Étienne Brûlé who explored the Georgian Bay area in 1610–1612, mapped Southern Ontario and called the region the
Pays d'en Haut ("Upper Country"), in reference to the region being upstream of the Saint Lawrence River. The colony of the Pays d'en Haut was formally established in 1610 as an administrative dependency of Canada, and was for defence and business rather than a settlement colony. The territory of the Pays-d'en-Haut was quite large and would today include the province of Ontario, as well as, in whole or in part, the American states of Minnesota, Wisconsin, Illinois, Indiana, Michigan, Ohio, Pennsylvania and New York. Indigenous peoples were the vast majority of the Pays d'en Haut population. '' region of
New France, an area that included most of Ontario As for Northern Ontario, the English explorer
Henry Hudson sailed into
Hudson Bay in 1611 and claimed its drainage basin for England. The area would become known as
Rupert's Land. De Champlain reached Lake Huron in 1615, and French missionaries, such as the
Jésuites and
Supliciens, began to establish posts along the Great Lakes. The French allied with most Indigenous groups of Ontario, all for the fur trade and for defence against Iroquois attacks (which would later be called the
Iroquois Wars). The French would declare their Indigenous allies to be subjects of the King of France and would often act as mediators between different groups. The Iroquois later allied themselves with the British. From 1634 to 1640, the Huron were devastated by European infectious diseases, such as
measles and
smallpox, to which they had no immunity. By 1700, the Iroquois had been driven out or left the area that would become Ontario and the Mississaugas of the Ojibwa had settled the north shore of
Lake Ontario. The remaining Huron settled north of Quebec City. During the
French and Indian War, the North American theatre of the
Seven Years' War of 1754 to 1763, the British defeated the armies of New France and its Indigenous allies. In the
Treaty of Paris 1763 France ceded most of its possessions in North America to Britain. Using the
Quebec Act, Britain re-organised the territory into the
Province of Quebec.
Province of Quebec (1763–1791) commemorating the
United Empire Loyalists, a group of settlers who fled the
United States during or after the
American Revolution In 1782–1784, 5,000
United Empire Loyalists entered what is now Ontario following the
American Revolution. The Kingdom of Great Britain granted them land and other items with which to rebuild their lives. A second wave of Americans, not all of them necessarily loyalists moved to Upper Canada after 1790 until the pre-war of 1812, many seeking available cheap land, and at the time, lower taxation. By 1798, there were eight districts: Eastern, Home,
Johnstown,
London, Midland,
Newcastle,
Niagara, and Western. By 1826, there were eleven districts:
Bathurst, Eastern,
Gore, Home, Johnstown, London, Midland, Newcastle, Niagara,
Ottawa, and Western. 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. 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 the British, Canadian
fencibles and militias, and
First Nations warriors. However, the Americans eventually gained control of Lake Erie and Lake Ontario. The 1813
Battle of York saw American troops defeat the garrison at the Upper Canada capital of
York. The Americans looted the town and burned the Upper Canada Parliament Buildings during their brief occupation. The British would
burn the American capital of Washington, D.C. in 1814. , during the
War of 1812.
Upper Canada was an active theatre of operation during the conflict. 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 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 following decades. 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. Unrest in the colony 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 power. 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, the first
mayor of
Toronto, led the
Upper Canada Rebellion. In Upper Canada, the rebellion was quickly a failure. Mackenzie escaped to the
United States, where he declared the
Republic of Canada on
Navy Island on the Niagara River.
Canada West (1841–1867) Although both rebellions were put down in short order, the British government sent
Lord Durham to investigate the causes. He recommended responsible government be granted, and 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 initially at
Kingston, and Upper Canada becoming known as
Canada West. Responsible government was achieved 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. from 1855. Canada West formed the western portion of the
Province of Canada. In 1849, the districts of southern Ontario were formed into 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. 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 the United States, various industries such as timber, mining, farming and alcohol distilling benefited tremendously. A political stalemate developed in the 1850s, between finely balanced political groups: conservative and reform groups from Canada West and Canada East aligned against reform and liberal groups from Canada East each group having some support from
French-Canadian and English-Canadian legislators. There was also a fear of aggression from the United States during and immediately after the
American Civil War. These factors led to the formation of the
Great Coalition in the elected Legislative Assembly, which initiated 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 the four provinces of 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 the Protestant and Catholic minorities. 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.
Canadian province (1867–present) 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. ,
Premier of Ontario from 1872 to 1896 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 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 increases 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. 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. 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 and the
McLaughlin Motor Car Company (later
General Motors Canada) was founded in 1907. The motor vehicle industry became the most lucrative industry for the Ontario economy during the 20th century. In July 1912, the
Conservative government of
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. in an effort to enforce
prohibition. The prohibition measures were introduced in 1916 and were not repealed until 1927. Influenced by events in the United States, the government of
William Hearst introduced
prohibition of alcoholic drinks in 1916 with the passing of the
Ontario Temperance Act. However, residents could distil and retain their own personal supply, and liquor producers could continue distillation and export for sale, allowing this already sizeable 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 strict community standards and revenue generation from the alcohol retail monopoly are upheld. 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. Ontario's official language is English, although there exists a number of
French-speaking communities across Ontario. French-language services are made available for communities with a sizeable French-speaking population; a service that is ensured under the
French Language Services Act of 1989. == Demographics ==
