The 45th Canadian Parliament is the current legislative session of the Parliament of Canada, which began on May 26, 2025, with the membership of the House of Commons having been determined by the results of the 2025 federal election held on April 28.

The session was opened personally by Charles III, King of Canada, on May 27, 2025, during his first royal visit to Canada as monarch. This was the first time in over half a century that the reigning monarch had opened parliament, since Elizabeth II did so for the 23rd Canadian Parliament in 1957, as well as the first time the sovereign had personally read the Speech from the Throne since Elizabeth II did so at the opening of the third session of the 30th Canadian Parliament in 1977.
