Stéphane Dion, making his acceptance speech after winning the party leadership.
In 2006, the Liberal Party of Canada held a leadership election to choose a successor to outgoing leader Paul Martin. Martin had announced that he would not lead the Liberals into another election, following his party's defeat in the 2006 federal election in Canada. The party's biennial convention, already scheduled to occur from November 29 to December 1, 2006, in Montreal's Palais des congrès, was followed by the party's leadership convention at the same venue occurring December 2 to December 3, 2006.
After four ballots, former cabinet minister and dark horse candidate Stéphane Dion won the leadership on December 2, 2006. As the winner, Dion led the Liberal Party into the 2008 federal election.
This was the only Liberal Party leadership convention in-between 1958 and 2025 in which none of the contenders had previously run for the party's leadership. Michael Ignatieff, who finished as runner-up, would later run again for the party's leadership in 2009 and was elected unopposed, while Martha Hall Findlay, who was eliminated in the first round of this election, ran again in 2013, finishing third.
