Parliament is Canada's federal legislative institution, comprising three components: the Crown (represented by the Governor General), the Senate (appointed members), and the House of Commons (elected Members of Parliament). Parliament debates and passes federal laws, approves government spending, and holds the government accountable. The House of Commons, where elected MPs represent constituencies, is the primary democratic chamber. The Senate provides review and can propose amendments to legislation. Parliament sits in the Parliament Buildings on Parliament Hill in Ottawa. Parliamentary sessions include Question Period for accountability, debates on legislation, and committee work examining issues in detail.
