Legislative Assembly of Ontario

The Legislative Assembly of Ontario (also known as Ontario Legislative Assembly or Ontario Legislature), is the legislature of the Canadian province of Ontario, and is the second largest provincial legislature of Canada. It is located in the Ontario Legislative Building at Queen's Park in Toronto.

The British North America Act section 69 stipulates "There shall be a Legislature for Ontario consisting of the Lieutenant-Governor and of One House, styled the Legislative Assembly of Ontario". The Legislative Assembly is unicameral, without an upper house, with 107 seats representing ridings elected through a first-past-the-post electoral system across the province.

The Legislative Assembly is informally known as the "Ontario Provincial Parliament". This is because unlike the other Canadian provinces, members of the assembly refer to themselves as "Members of the Provincial Parliament" (MPPs) as opposed to "Members of the Legislative Assembly" (MLAs) as in many other provinces. Ontario is the only province to do so, in accordance with a resolution passed in the Assembly on April 7, 1938. However, the Legislative Assembly Act, R.S.O. 1990, c. L10 refers only to "members of the Assembly".

The 40th Legislative Assembly of Ontario was elected on October 6, 2011. The first session of the 40th Legislative Assembly opened on November 22, 2011 and ended on October 15, 2012.
