The 2003 Progressive Conservative leadership election was held on May 31, 2003 to elect a leader of the Progressive Conservative Party of Canada. Peter MacKay was elected as leader to replace former Prime Minister Joe Clark, who had retired as party leader. In the end, five candidates emerged as challengers for the leadership by the convention date. Two other candidates had participated in the race but both withdrew as contestants before the vote. Quebec Member of Parliament (MP) André Bachand withdrew his candidacy from the race due to financial concerns and backed Peter MacKay. Former Cabinet Minister and Quebec MP Heward Grafftey also withdrew his candidacy from the race due to health concerns and backed David Orchard.
