The Parliamentary Cycle:
Prorogation of Parliament
The prorogation of Parliament ends a session. This is done by the Governor General, on the advice of the Prime Minister, either by means of a special ceremony in the Senate Chamber, or by the issuing of a proclamation published in the Canada Gazette. Both the Senate and the House of Commons stand prorogued until the opening of the next session
