Since 2004, the party has elected its leaders on a one member, one vote basis using a ranked ballot. The process is weighted so that each riding is allocated 100 points, divided proportionately among candidates based on their percentage of the vote in that riding.[1] This process was first used in the 1998 Progressive Conservative leadership election, a predecessor party of the modern Conservative Party.
Poilievre won the leadership election in a landslide, carrying 330 of 338 ridings with at least a plurality. The only other candidate to win a plurality in any ridings was Jean Charest, whose support mostly came from Quebec, though Poilievre still won 72 of the province's 78 ridings. Charest won his former federal riding of Sherbrooke, all other candidates losing their ridings to Poilievre.[3]
