The House of Commons is one of three parts of the Parliament of Canada, and is composed of: the Monarch, the Senate, and the House of Commons. The Parliament is the federal legislature of Canada, seated at Parliament Hill in Ottawa. 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 her representative, normally the governor general, provides royal assent to make bills into law.
