The Legislative Assembly is the second largest Canadian provincial deliberative assembly by number of members after the National Assembly of Quebec . The Assembly meets at the Ontario Legislative Building at Queen's Park in the provincial capital of Toronto . </P> <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 124 seats (increased from 107 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> As 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>
