Compared to Canadian political parties in general, and especially governing parties, there were very few restrictions regarding membership and regarding eligibility to vote in a leadership election in Alberta's PC Party. First, Alberta PC party rules did not forbid members from holding in rival parties. Some other Alberta parties, notably the Liberals and New Democrats do forbid their members from being members of other parties although the Alberta Alliance removed a similar restriction, possibly in response to Ted Morton's PC leadership candidacy. Second and perhaps more significantly, the Progressive Conservatives, as in 1992, allowed anyone who wished to vote in the leadership election to purchase a five-dollar membership right up to the polling day—memberships were even available for purchase at the polling stations. This was very unusual in Canada—in fact no other major federal or provincial party is known to allow leadership voters to buy memberships on polling day. Even those parties that do not employ delegated leadership conventions and allow the general membership to vote for the leader usually have a deadline for purchasing memberships of no later than seven days prior to the vote.
