2021 Canadian federal election

The 2021 Canadian federal election was held on September 20, 2021, to elect members of the House of Commons to the 44th Canadian Parliament. The writs of election were issued by Governor General Mary Simon on August 15, 2021, when Prime Minister Justin Trudeau requested the dissolution of parliament for a snap election.

Trudeau won a third term as prime minister, his second minority government. Though the Liberals were hoping to win a majority government to govern alone, the results were mostly unchanged from the 2019 Canadian federal election. The Liberals won the most seats at 160; as this fell short of the 170 seats needed for a majority in the House of Commons, they formed a minority government with support from other parties. The Liberals set a record for the lowest vote share of a party that would go on to form government, winning 32.6 per cent of the popular vote, while losing the popular vote to the Conservatives as they did in 2019.

The Conservatives led by Erin O'Toole won 119 seats, two fewer than their result in 2019, and continued as the Official Opposition. The Bloc Québécois led by Yves-François Blanchet won 32 seats, unchanged from the prior election. The New Democratic Party led by Jagmeet Singh won 25 seats, a net increase of one seat, but nonetheless fell short of expectations. The Green Party maintained two seats but party leader Annamie Paul was defeated for the third time in her riding of Toronto Centre. The party received 2.3 per cent of the popular vote, approximately a third of what they won in 2019. The People's Party did not win any seats, despite winning nearly 5 per cent of the popular vote, and party leader Maxime Bernier was defeated for the second time in his riding of Beauce.

Trudeau faced public blowback for holding an election in the middle of a global pandemic due to his expectation that doing so could translate his supposed rallying popularity into a landslide victory. Criticism worsened when Trudeau failed to win by a majority and instead repeated his 2019 election showing. It was later alleged that China attempted to meddle in the election to influence Canadian foreign policy.

Following the election, Paul resigned as Green Party leader two months after the election, and O'Toole was ousted as leader by his party's caucus in February 2022 over the poor showing in the election and other controversies ongoing at the time. In March 2022, the NDP formed a confidence and supply agreement with the Liberals.
