Before the arrival of Europeans, Ontario was inhabited by the people algonquiens (Saulteux, Cries and Algonquins) and Iroquoians’ (Iroquois and the Huron ones). The French explorer Etienne Brule explored part of the area of Ontario of 1610 to 1612. The English explorer Henry Hudson sailed on Hudson Bay in 1611 and asserted the neighbourhoods for England, but Samuel de Champlain reached Lake Huron in 1615 and the French missionaries started to establish missions with the accesses of the Large Lakes. French colonization was blocked by the hostilities with Iroquois, which were combined to the English later. Great Britain establishes counters in Hudson Bay towards the end of XVIth century, starting a fight for domination of Ontario. The treaty of Paris in 1763 put an end to the Seven Year war by almost yielding all the French empire in America (New-France) to the British. The area, now called, Ontario was annexed to Quebec in 1774. The constitutional law of 1791 divided Quebec into two parts, Canadas: High-Canada in the west of the river of Outaouais and Low-Canada in the east. The American troops of the war of 1812 set fire to Toronto Ontario in 1813. After the war, in Ontario much of British immigrants came to settle in High-Canada, and started to irritate itself against the aristocratic one Compact Family who controlled the area, just as Click castle controlled in Low-Canada. Then, the rebellion in favour of the responsible government to the two areas, under Louis-Joseph Papineau by the Patriots Canadian-French in Low-Canada (Ontario), and under William Lyon Mackenzie in High-Canada by the Scottish “Patriots”. In Ontario, although the two rebellions were crushed, the British government sent Lord Durham to inquire into the causes of the riots. It recommended the granting of political autonomy and the remelting of the colonies in order to assimilate the Quebecois - the British of High-Canada were now majority in Canada. The two colonies were then amalgamated in the Province of Canada in 1841, with Ontario under the name of Canada-West. The autonomous parliamentary government was granted in 1849, fearing a possible American aggression caused by the American Civil War, Canada, New Brunswick and Nova Scotia decided to amalgamate themselves in the federation (named wrongly confederation) in 1867. The conflict supported between the two parts of the Province of Canada caused their separation: they also entered the federation like two distinct provinces, Ontario and Quebec. At the end of XIXth century the part of the North-West was allotted to Ontario, but there remains separatist fort running which would like that it is attached to Manitoba. Starting with the construction of the transcontinental railroad through the large plains to the Colombia-British, the industry of Ontario made great strides. The mining of Ontario started at the beginning of XXth century. The nationalist movement in Quebec pushed several commercial companies to migrate towards Ontario. Toronto then replaced Montreal like Metropole and economic center of Canada, Ontario. The currency of Ontario is’’ Faithful it started, faithful it will remain’’. The emblem and the provincial flower of Ontario are the white trille. The provincial bird is the Dive huard, like Canada; the provincial tree is the white pine and the provincial mineral of Ontario is the amethyst.
