The Canadian Alliance, a conservative political party in Canada, held two leadership elections to choose the party's leader. The first was held shortly after the party's founding in 2000, and the second was held in 2002. The party merged with the Progressive Conservative Party of Canada in 2003 to form the Conservative Party of Canada.
The 1987 founding convention of the Reform Party of Canada elected Preston Manning as party leader by acclamation. Manning was re-ratified as leader at every subsequent convention of the party without opposition.
The Reform Party became the "Canadian Reform Conservative Alliance" (better known as the "Canadian Alliance") in 2000 and had its first contested leadership election. Canadian Alliance leadership votes were conducted via a pure one member, one vote system in which each party member cast a ballot with equal weight.
In the CA's system, the leader was the candidate who received 50% plus one of all votes cast (i.e., an absolute majority). If no candidate had an absolute majority on the first ballot, the top two candidates participated in a run-off election several weeks after the first ballot.
