The Ontario Legislative Assembly is the province's unicameral legislature, located at Queen's Park in Toronto, where 124 elected Members of Provincial Parliament (MPPs) represent constituencies across Ontario. As Canada's most populous province, Ontario's legislature handles matters affecting nearly 15 million people. The Assembly passes laws, approves budgets, and holds the provincial government accountable. The party or coalition with majority support forms government, with its leader becoming Premier. Ontario's legislative decisions significantly affect municipalities through the Municipal Act, planning legislation, funding programs, and provincial-municipal relationships across Canada's most urbanized province.
