The 43rd Canadian Parliament was in session from December 5, 2019, to August 15, 2021, with the membership of its Lower House, the House of Commons of Canada, having been determined by the results of the 2019 federal election held on October 21, 2019. Parliament officially resumed on December 5, 2019, with the election of a new Speaker, Anthony Rota, followed by a speech from the throne the following day. On August 15, 2021, Prime Minister Justin Trudeau advised Governor General Mary Simon to dissolve Parliament and issue the writ of election, leading to a 5-week election campaign period for the 2021 federal election.
