Prorogation is the end of a parliamentary session in the Parliament of Canada and the parliaments of its provinces and territories. It differs from a recess or adjournment, which do not end a session; and differs from a complete dissolution of parliament, which ends both the session and the entire parliament, requiring an election for the House of Commons in the bicameral federal parliament and the singular legislative chamber of the unicameral provincial parliaments.

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.
