By election to the 25th Canadian Parliament

One by-election to the 25th Canadian Parliament was held to fill a vacancy in the Canadian House of Commons between the 1962 federal election and the 1963 federal election. The Progressive Conservative Party of Canada led a minority government for the entirety of the 25th Canadian Parliament.

The vacancy was created due to the resignation of a New Democratic Party Member of Parliament. Tommy Douglas, elected leader of the New Democratic Party a year prior to the 1962 general election in the 1961 New Democratic Party founding convention, did not gain his riding in the 1962 election, and instead ran in a later by-election.
