The Canadian federal election of 1925 was held on October 29 to elect members of the Canadian House of Commons of the 15th Parliament of Canada. Prime Minister William Lyon Mackenzie King's Liberal Party was defeated by the Progressive Party, led by Robert Forke, who became the first prime minister not from either the Liberal or Conservative parties. King's Liberals were reduced to being the main opposition party, with the Conservatives under leader Arthur Meighen coming in a close third. The Labour Party, who ran together with the Progressives, was also able to increase its representation, at the expense of the Liberals.

Seat Count by Province
The Progressive Party fell just short of a majority on its own, but was able to form one with the support of the Labour Party and United Farmers, and Robert Forke allowed politicians from the two parties to sit in his government.
The Liberals were reduced significantly and King even lost his own seat to a Progressive Party candidate. However, a Liberal member in Quebec resigned his Montreal seat of Laurier-Outremont, and King won a by-election there and stayed on as leader of his party and the official opposition.
The Conservative leader, Arthur Meighen, missed out once again on re-taking the office of prime minister and, despite expressing a wish to stay on as leader due to the party's low losses, he was replaced by R.B Bennett, the only Conservative to win a seat in Alberta.
