Legislature of Ontario

The Legislature of Ontario is made of two elements: the lieutenant governor, and the Legislative Assembly of Ontario. The Legislature was established on July 1, 1867 following the creation of Ontario as one of the first four provinces of Canada. The seat of the Legislature has been the Ontario Legislative Building in Queen's Park, Toronto since 1893.
Like the Canadian federal government, Ontario uses a Westminster-style parliamentary government, in which members are sent to the Legislative Assembly after general elections. Like all the provincial governments, the concept of responsible government is followed, and the Premier of Ontario and their cabinet is accountable to the Legislative Assembly.

List of Parliaments

This is a list of the Parliaments of the Ontario Legislative Assembly, the legislature of the Canadian province of Ontario, since Canadian Confederation in 1867. The Legislative Assembly has existed since 1867 when the British North America Act, 1867 severed the Province of Canada into two new provinces, with the portion then called Canada West becoming Ontario. For the Parliaments prior to Confederation, see Parliament of the Province of Canada and Parliament of Upper Canada.
