By-elections to the 43rd Canadian Parliament
By-elections to the 43rd Canadian Parliament were held to fill vacancies in the House of Commons of Canada between the 2019 federal election and the 2021 federal election. The 43rd Canadian Parliament has existed since 2019 with the membership of its House of Commons having been determined by the results of the Canadian federal election held on October 21, 2019. The Liberal Party of Canada had a minority government during this Parliament.
Two by-elections were held on October 26, 2020 due to the resignation of Finance Minister Bill Morneau (Liberal, Toronto Centre) on August 17, 2020 to run for Secretary-General of the OECD, and the resignation of Michael Levitt (Liberal, York Centre) effective September 1, 2020 to become the President and CEO of the Canadian Friends of Simon Wiesenthal Centre for Holocaust Studies.
A third by-election was pending in the riding of Haldimand—Norfolk following the resignation of Conservative MP Diane Finley on May 20, 2021, but was cancelled due to the 2021 Canadian federal election being called for September 20, 2021.
The writ for a by-election must be dropped no sooner than 11 days and no later than 180 days after the Chief Electoral Officer is officially notified of a vacancy via a warrant issued by the Speaker. Under the Canada Elections Act, the minimum length of a campaign is 36 days between dropping the writ and election day.
