The first Progressive Conservative Party of Canada leadership election was held in 1927, when the party was called the Conservative Party. Prior to then the party's leader was chosen by the caucus or in several cases by the Governor General of Canada designating a Conservative MP or Senator to form a government after the retirement or death of an incumbent Conservative Prime Minister.^[1]

There have been two permanent leaders since 1927 who were not chosen by a leadership convention. Arthur Meighen agreed to serve a second term as leader in 1941 on condition that he would not have to contest the position. The party agreed since the party was desperate for a leader of Meighen's stature. Jean Charest was one of only two Progressive Conservative Members of Parliament returned in the 1993 election and was appointed leader by the party's executive with the decision later being affirmed at a regular party convention two years later. The Conservative Party became the Progressive Conservative Party in 1942.^[1]

All leadership conventions were delegated conventions, except in 1998 when a one member, one vote process was used in which each riding was allocated 100 points which were distributed among candidates by proportionally. For the 2003 leadership election, the party reverted to use of a delegated convention, ostensibly because of the cost of using a one member, one vote process (though it has been argued that the party feared that use of one member, one vote would make an outside takeover of the party easier due to a decline in membership). In 2003, the party merged with the Canadian Alliance to form a new Conservative Party of Canada. This party adopted the one member, one vote process the Tories had used in 1998.

Note on tables: Green box indicates winner. Pink box indicates candidate eliminated from ballot for receiving the fewest votes. Blue box indicates candidate withdrew from balloting.

Held in Winnipeg, Manitoba on October 11, 1927.

First ballot was conducted October 24, 1998; second ballot was conducted November 14, 1998.

The 1998 election used a point system that allocated 100 points to each riding, regardless of the number of votes cast in the riding. The candidate who won a majority of points (not necessarily a majority of voters) would win the leadership. All party members were eligible to cast a vote. The 100-point-per-riding system was again used by the Conservative Party of Canada in its 2004 leadership race.
