The House of Commons of Canada is the lower house of the Parliament of Canada. Together with the Crown and the Senate of Canada, they comprise the bicameral legislature of Canada.

The Parliament of Canada is the federal legislature of Canada, seated at Parliament Hill in Ottawa, and is composed of three parts: the King, the Senate, and the House of Commons. By constitutional convention, the House of Commons is dominant, with the Senate rarely opposing its will. The Senate reviews legislation from a less partisan standpoint and may initiate certain bills. The monarch or his representative, normally the governor general, provides royal assent to make bills into law.
