Both of Alberta's opposition parties, the Liberal Party and the NDP, boycotted the election in demonstration of their opposition to the process. As a result, the only candidates to contest the election were representatives of the right-of-centre Alberta Progressive Conservatives, Alberta Alliance Party and Social Credit parties, and a number of independents. After much pressure from the Liberal and NDP camps (who did not want their supporters to feel compelled to vote for a right-of-centre candidate), polling officers were instructed to advise voters on election day that they did not have to vote in the Senate election.
