2025 Canadian federal election in the context of "30th Canadian Ministry"

The House of Commons of Canada (French: Chambre des communes du Canada) is the lower house of the Parliament of Canada. Together with the Crown and the Senate of Canada, they comprise the bicameral legislature of Canada.

The House of Commons is a democratically elected body whose members are known as members of Parliament (MPs). The number of MPs is adjusted periodically in alignment with each decennial census. Since the 2025 federal election, the number of seats in the House of Commons has been 343.

The 1988 Canadian federal election was held on November 21, 1988, to elect members to the House of Commons of Canada of the 34th Parliament of Canada following the dissolution of the House on October 1. It was an election largely fought on a single issue, the Canada–United States Free Trade Agreement (CUSFTA); the Progressive Conservative Party campaigned in favour of it, whereas the Liberal Party and the New Democratic Party (NDP) campaigned against it.

The incumbent Progressive Conservative Party, led by Brian Mulroney, was reelected with a second majority government, although based on less than half the votes cast. Mulroney was the party's first leader since John A. Macdonald to win a second consecutive majority government. Additionally, this election was the last election in which the Progressive Conservatives would poll over 40 percent of the vote, as this would not recur until 2025, under the banner of the Conservative Party of Canada.

Nepean is a federal electoral district in Ontario, Canada that was represented in the House of Commons of Canada from 1988 to 1997, and was reinstated during the 2012 electoral redistribution. The riding has been represented by Mark Carney, Leader of the Liberal Party and Prime Minister of Canada, since 2025.

Abitibi—Baie-James—Nunavik—Eeyou (formerly known as Abitibi, Abitibi—Baie-James—Nunavik and Nunavik—Eeyou) is a federal riding in the province of Quebec, Canada, that has been represented in the House of Commons of Canada since 1968. Since the 2025 federal election, its Member of Parliament (MP) has been Mandy Gull-Masty of the Liberal Party of Canada.

The riding of Abitibi was created in 1966 (ahead of the 1968 election), before it was renamed Abitibi—Baie-James—Nunavik in 1998. It was abolished in 2003 (ahead of the 2004 election); most of its territory was incorporated into Nunavik—Eeyou, which was then renamed Abitibi—Baie-James—Nunavik—Eeyou in 2004.

The leader of the Official Opposition (French: chef de l'Opposition officielle) is the member of Parliament (MP) who leads the Official Opposition in Canada. This is typically the leader of the party possessing the most seats in the House of Commons that is neither the governing party nor part of a governing coalition.

Pierre Poilievre, MP for Battle River—Crowfoot, has been the leader of the Official Opposition since August 2025. Poilievre previously served in the role from September 2022 to April 2025, when he lost his seat in Carleton in the 2025 federal election. He was elected to his current seat in an August by-election, once again becoming leader of the Opposition.
