2017 Conservative Party of Canada leadership election

The 2017 Conservative Party of Canada leadership election was held on May 27, 2017. Party members chose Andrew Scheer as leader, replacing Stephen Harper, who led the Conservative Party of Canada as its leader from 2004 following the merger of the Canadian Alliance and Progressive Conservative parties. Harper led the party through five federal elections: the party increased its seat count in the House of Commons in 2004, formed two minority governments in 2006, and 2008, and then a majority government in 2011. Following the defeat of the party in the 2015 federal election on October 19, Harper tendered his resignation as party leader. In a statement, Conservative Party President John Walsh said he had spoken to Harper, "and he has instructed me to reach out to the newly elected parliamentary caucus to appoint an interim Leader and to implement the leadership selection process."

259,010 party members were eligible to vote in the leadership contest. 141,000 members cast a vote. According to raw voting figures, Scheer received 62,593 votes on the final ballot compared to 55,544 votes for Bernier with 23,000 voters who had voted in the first round ranking neither Scheer or Bernier in their ranked ballot. Votes were apportioned among ridings so that each riding was allocated 100 points, regardless of the number of voters, resulting in 17,222.20 points (50.95%) for Scheer and 16,577.80 points (49.05%) for Bernier.

Subsequent to the election, fourth placed candidate Brad Trost and his campaign were fined $50,000 by the Conservative Party of Canada for allegedly leaking the party's membership list to the National Firearms Association. Trost denied that he or any of his staff leaked the list. On February 11, 2019, the Conservative Party released a statement from its Leadership Election Organizing Committee (LEOC) which concluded: "In short, LEOC does not believe there is evidence that the Trost Campaign was responsible for leaking of the membership list...." The fine was therefore removed from the Brad Trost Campaign. Trost went on to lose renomination as the party candidate for his riding during the 43rd Federal election on March 10, 2018, to Corey Tochor, former speaker of the Saskatchewan Legislature.

Criticism has been raised about how the party memberships were handled, with some prominent members saying they never received a ballot, even after contacting the party about it.

In addition, the result of the leadership race and party handling was questioned by some supporters of such as runner-up Maxime Bernier and fifth place candidate Kellie Leitch due to discrepancies in the final ballot count, specifically a gap between the number of ballots cast and the announced result – a 7,466 vote discrepancy, which is greater than Andrew Scheer's 7,049 votes margin of victory in the final round. There was criticism over the exact role of the accounting firm Deloitte during the voting process – a deal revealed that Deloitte was not specifically tasked with auditing the vote but "observe" the counting process. It was also reported that some of Brad Trost's supporters contravened the Elections Act and party membership rules by offering incentives to vote. Dimitri Soudas, a former Stephen Harper aide, pointed out that it violated election rules and it benefited Scheer's campaign but the ballots have been destroyed so the results stood.

Many considered Scheer's victory as an upset, given Bernier's consistent frontrunner status in the polls.

Interim leadership
Conservative Party president John Walsh's letter to caucus stated that only Members of Parliament (MPs) would vote for the interim leader, but Conservative Senators pointed out that the party constitution states that the entire parliamentary caucus votes. The caucus allowed senators to vote, declining to adopt the provisions of the Reform Act that would have only allowed MPs to vote.

The caucus chose Rona Ambrose, MP for Sturgeon River—Parkland, Alberta and former Minister of Health, as interim leader at its first meeting on November 5, 2015, in a vote by preferential ballot. Ambrose, as the interim leader, also served as Leader of the Official Opposition in the Parliament of Canada until a permanent leader was chosen. She defeated Candice Bergen, Diane Finley, Mike Lake, Rob Nicholson, Erin O'Toole, and the joint ticket of Denis Lebel and Michelle Rempel in the caucus vote.

Under the party's constitution, Ambrose, as the interim leader, could not run for the permanent position.

Leadership election timing
Following Harper's resignation, debate emerged within the Conservative Party regarding the timing of the leadership election. Some members of the party's national council called for a leadership convention as early as May 2016 according to Maclean's magazine. However, interim leader Rona Ambrose said there was a consensus among the party's caucus that the leadership election should not be rushed and should be held sometime in 2017. In a December 2015 interview, Ambrose said the party would take its time allowing all members, including those not already involved in politics, to build a strong candidacy. "If we take a little extra time, that will mean we'll have a better leadership race."

The Conservative Party's Leadership Election Organizing Committee (LEOC) met at Toronto's Albany Club January 15–17, 2016 to discuss the process for the Party to elect its next leader. Among its decisions, LEOC selected May 27, 2017, for Conservative Party members to elect their next leader.

Rules and voting system
Only party members in good standing at 5pm Eastern Time on March 28, 2017, were allowed to vote. The fee for a party membership was raised from $15 to $25, an increase that was reversed on April 23, 2016, after criticisms that the move was "elitist". Membership fees could only be paid via personal cheque or credit card. Cash payments were not permitted. This new requirement was intended to prevent the election being dominated by new members, and to prevent anyone other than the individual member, such as a candidate's campaign, from signing up scores of members and paying the membership fees in cash out of campaign funds. Despite this, the Conservative Party confirmed irregularities with 1,351 memberships connected to prepaid credit cards that it subsequently struck from its membership roll.

Voting was on a one member one vote basis using a ranked ballot; however votes were calculated so that each electoral district had equal weight with each electoral district allocated 100 points. Candidates were assigned a point total based on his or her percentage of the vote in each electoral district. To win, a candidate must receive at least 16,901 points which would be a majority.

O'Leary supported using a "big stick" federally in order to bring provincial governments in-line with federal policies, cutting waste in military spending, supports a peacekeeping role for the military, cutting carbon emissions through criminal sanctions rather than a carbon tax, supports current immigration policy but also wishes to "fast-track" the citizenship applications of skilled immigrants, asserted he would support LGBTQI people, legalize marijuana and defend reproductive rights.

 * Other information: O'Leary withdrew from the election despite polls showing he was the frontrunner. He stated that while he believed he could win the leadership election, he would be unable to defeat Justin Trudeau in the next federal election due to his inability to speak French fluently and his lack of support in Quebec. He endorsed Maxime Bernier. As his withdrawal took place after the deadline, O'Leary remained on the final leadership ballot.
