What is the role of a Member of Parliament?

A Member of Parliament (MP) is an elected representative who sits in the federal House of Commons in Ottawa. There are 343 MPs after the 2024 federal redistribution (343 electoral districts, called 'ridings', distributed across Canada roughly proportional to population). MPs are elected by first-past-the-post voting in general elections, normally held every four years on the third Monday of October under the federal fixed-election-date provision in section 56.1 of the Canada Elections Act.

MPs have several principal roles. As legislators, they debate and vote on bills, propose private members' bills, and serve on standing or special committees that scrutinise government activity and conduct policy studies. As constituency representatives, they address concerns of constituents in their riding, including immigration cases, federal-program problems, and policy consultation. As party members (in most cases), they support their party's positions and follow party whip directions on most votes (party discipline is stronger in Canada than in the United States).

MPs have specific powers and privileges under parliamentary privilege (a constitutional principle inherited from Westminster). Privileges include freedom of speech in the House (statements made in the Chamber cannot be the subject of legal proceedings), freedom from arrest in civil cases during a parliamentary session, and the exclusive right of the House to discipline its members. The Conflict of Interest Code for Members of the House of Commons (adopted 2004) governs ethics, financial disclosure, and conflict-of-interest standards for MPs.

MPs receive a sessional indemnity (annual salary) of about $203,100 in 2025 plus expense allowances and pension benefits under the Members of Parliament Retiring Allowances Act. Cabinet ministers, the Prime Minister, the Speaker, and parliamentary secretaries receive additional compensation. MPs serve from when they are declared elected by Elections Canada until the dissolution of Parliament (or earlier resignation, death, or expulsion). The House of Commons has 335 sitting members at typical points in a Parliament after deducting the Speaker (who votes only to break ties) and accounting for any vacancies before by-elections.
