By-elections to the 39th Canadian Parliament

By-elections to the 39th Canadian Parliament were held to fill vacancies in the House of Commons of Canada between the 2006 federal election and the 2008 federal election. The Conservative Party of Canada led a minority government for the entirety of the 39th Canadian Parliament, although their seat total increased as a result of by-election results.

Twelve vacancies occurred during the life of the Parliament. Nine of these were filled by by-elections and the remaining three were filled at the 2008 federal election.
