The first Liberal leadership convention was held on August 7, 1919. Balloting continued until one candidate won a majority of votes. After the 1919 convention, a system was adopted where the candidate with the fewest votes on a given ballot is automatically dropped. More recently, any candidate with less than 5% of the vote on the first ballot is also automatically dropped. Since 1919, time has also been given between ballots for candidates to announce if they wish to withdraw and throw their support to another candidate.
