2003 Progressive Conservative leadership election
Chandler withdrew before voting began to endorse Prentice. Estimates suggest that Chandler had six committed delegates from Calgary ridings who voted in favour of Prentice. After the second ballot, Brison dropped off and supported Prentice. Brison was the only candidate to gain votes on this ballot compared to his first ballot result; all of the other candidates lost votes. After the third ballot, Orchard threw his support to MacKay after the two men signed an agreement committing MacKay to not merge the PCs with the Canadian Alliance, and to hold a review of the Canada-U.S. Free Trade Agreement.
Results
Two other candidates had participated in the race but both withdrew as contestants before the vote. This deal promised the party would review the Canadian-American Free Trade Agreement, and that it would not cooperate or merge with the Canadian Alliance. This controversy continued when MacKay ignored the agreement, and signed an agreement to merge his party with the Canadian Alliance to form the new Conservative Party of Canada.
