The Legislature of Ontario (often colloquially referred to as the Provincial Parliament of Ontario) is the legislature of the Province of Ontario, the most populous subnational jurisdiction within Canada.
The current legislature was established in 1867 upon the creation of Ontario as one of the first four provinces at Canadian Confederation. It is one of the three successor legislatures of the Parliament of the Province of Canada (along with the Parliament of Canada and the provincial Parliament of Quebec). The legislature is composed of two elements: the lieutenant governor of Ontario (representing the King of Canada), and the elected Legislative Assembly of Ontario.
Unlike most other provinces, Ontario's provincial legislators are not referred to as members of the Legislative Assembly (MLAs), having instead adopted the title of member of Provincial Parliament (MPP), a title that was formally adopted by resolution of the legislature in 1938.
The seat of the Legislature has been the Ontario Legislative Building, located in Queen's Park, an actual urban park located in the city of Toronto that was named in honour of Queen Victoria. For that reason, the term Queen's Park is used as an informal moniker for the building or the legislature itself at a variety of settings.
