<P> The Legislative Assembly was established by the British North America Act, 1867 (later re-titled Constitution Act, 1867), which dissolved the Province of Canada into two new provinces, with the portion then called Canada West becoming Ontario . The Legislature has been unicameral since its inception, with the Assembly currently having 107 seats (increased to 122 as of the 42nd Ontario general election) representing electoral districts ("ridings") elected through a first - past - the - post electoral system across the province . </P> <P> Like at the federal level in Canada, Ontario uses a Westminster - style parliamentary government, in which members are elected to the Legislative Assembly through general elections, from which the Premier of Ontario and Executive Council of Ontario are appointed based on majority support . The premier is Ontario's head of government, while the Lieutenant Governor, as representative of the Queen, acts as head of state . The largest party not forming the government is known as the Official Opposition, its leader being recognized as Leader of the Opposition by the Speaker . </P> <P> The Ontario Legislature is sometimes referred to as the "Ontario Provincial Parliament". 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 refers only to "members of the Assembly". </P> <P> The current assembly was elected on June 12, 2014 as part of the 41st Parliament of Ontario . The first session of the 41st Parliament opened on July 2, 2014 . On Friday May 2, 2014, the 40th Parliament of Ontario was dissolved by Lieutenant Governor David C. Onley on the advice of Premier Kathleen Wynne after the NDP and Progressive Conservative leaders said they would not support the Liberal minority government's budget . The election was held on June 12, 2014, as a result of which Kathleen Wynne's Liberal Party formed a majority government . </P>
