2020 Conservative Party of Canada leadership election

On 21 October 2019, the 2019 Canadian federal election was held. The Conservatives remained in opposition against a minority Liberal government. Under the Conservative Party's constitution, an election loss results in a leadership review at the next party convention. The following day, Scheer announced his intention to remain leader of the party.

As early as 23 October, there were reports that party members were already privately voicing dissatisfaction with Scheer's leadership, and suggestions that he could face a leadership challenge at the next party convention in April.{{cite news |last1=Mac Sweeney |first1=Cormac |title=Scheer could face party coup after election loss; reports suggest deep disappointment in leadership |url=https://edmonton.citynews.ca/2019/10/23/scheer-election-loss-disappointment-leadership/ |access-date=25 June 2020 |publisher=CityNews |date=23 October 2019}} By the end of the month, Conservative figures were making their criticism public, and an online petition was launched that called for Scheer to resign.{{cite news |last1=Levitz |first1=Stephanie |title=Scheer's leadership at centre of tensions brewing within Conservative party |url=https://globalnews.ca/news/6110035/andrew-scheer-conservative-leadership/ |access-date=25 June 2020 |publisher=Global News |date=31 October 2019}} Former MP and cabinet minister Peter MacKay described the election as "like having a breakaway on an open net and missing the net"; he attributed the loss to Scheer's socially conservative views, which he said "hung around [his] neck like a stinking albatross" and distracted from other policies and issues. MacKay's comments additionally fuelled speculation that he was vying for the leadership.{{cite news |last1=Breen |first1=Kerri |title=Peter MacKay says Tories missed shot on open net in federal election campaign |url=https://globalnews.ca/news/6104504/peter-mackay-federal-election-conservatives/ |access-date=25 June 2020 |publisher=Global News |date=30 October 2019}}

On 6 November, Scheer met with the Conservative caucus for the first time since the election, where they discussed the federal election and why the party failed to win. Scheer attributed the loss not to policy, but poor communication. During the meeting, the caucus voted against adopting the provisions of the Reform Act; as adopting them would have allowed the caucus to begin the process of ousting Scheer, his leadership was seen as safe until the April convention.{{cite news |last1=Zimonjic |first1=Peter |title=Scheer's leadership safe for now after Conservative caucus vote |url=https://www.cbc.ca/news/politics/andrew-scheer-post-caucus-election-1.5350662 |access-date=26 June 2020 |publisher=CBC News |date=6 November 2019}} However, criticism did not abate; a report in the Toronto Star cited calls for Scheer's resignation from within the business community, energy sector and several high-profile party insiders.{{cite news |last1=MacCharles |first1=Tonda |last2=Ballingall |first2=Alex |title=Alberta conservatives and business leaders angry at Conservative Leader Andrew Scheer |url=https://www.thestar.com/politics/federal/2019/11/28/conservative-leader-andrew-scheer-appoints-floor-crossing-liberal-as-deputy-leader.html |access-date=26 June 2020 |publisher=Toronto Star |date=28 November 2019}}

On 12 December, Scheer announced that he was stepping down as leader, pending the election of his successor. He also said he would stay on as MP for Regina—Qu'Appelle "for the near future".{{cite news |last1=Tunney |first1=Catherine |last2=Harris |first2=Kathleen |title=Andrew Scheer stepping down as Conservative Party leader |url=https://www.cbc.ca/news/politics/scheer-resigns-1.5393803 |access-date=12 December 2019 |publisher=CBC News |date=12 December 2019}} The leadership convention was scheduled for 27 June 2020.{{cite news |title=Conservatives to name new leader in June |url=https://globalnews.ca/news/6363879/conservative-party-leadership-june/ |access-date=26 June 2020 |agency=The Canadian Press |publisher=Global News |date=3 January 2020}}

The on-going COVID-19 pandemic affected the timing of the leadership election. On 12 March, Peter MacKay, Erin O'Toole, Rick Peterson and Leslyn Lewis suspended all public campaign events, while Marilyn Gladu "assess[ed] events and activities on a daily and event-by-event basis", due to public health guidelines.{{cite news|last1=Aiello|first1=Rachel|title=Conservative leadership contestants suspending campaign events due to COVID-19|publisher=CTV News|issue=12 March 2020|url=https://www.ctvnews.ca/politics/conservative-leadership-contestants-suspending-campaign-events-due-to-covid-19-1.4850482|access-date=26 June 2020}} The next day, 13 March, Gladu, Rudy Husny and Rick Peterson called for either the race to be postponed or for entry deadlines to be pushed back.{{cite news|last1=Platt|first1=Brian|date=13 March 2020|title=Conservative leadership notebook: COVID-19 pandemic throws a wrench into the race|publisher=Chronicle Herald|url=https://www.thechronicleherald.ca/news/canada/conservative-leadership-notebook-covid-19-pandemic-throws-a-wrench-into-the-race-424044/|access-date=26 June 2020}} On 19 March, Husny dropped out, citing an unwillingness to fundraise during a public health emergency.{{cite news|last1=Levitz|first1=Stephanie|date=19 March 2020|title=Tory leadership candidate says he's out of the race if deadlines don't change|agency=The Canadian Press|url=https://www.cbc.ca/news/politics/rudy-husny-leadership-deadline-1.5503646|access-date=26 June 2020}} Peterson followed on 20 March, criticizing the organizing committee's unwillingness to move the deadlines as unfair.

On 26 March, the Leadership Election Organizing Committee (LEOC) postponed the race, as well as cancelling debates planned for April and pushing back the membership deadline to 15 May. The LEOC did not set a new date, and said they would revisit the decision on 1 May. On 29 April, the LEOC announced the resumption of the contest, with the vote taking place entirely by mail-in ballot and without a convention. No definitive date was set for when the results would be announced, but the LEOC clarified that the results would be announced "as soon as those ballots can be properly processed and examined by scrutineers while respecting any health guidelines in place at that time."

On 19 June, Erin O'Toole accused MacKay's campaign of theft of confidential campaign data and strategy including Zoom conference videos after discovering that their "systems were hacked earlier this week".{{cite twitter|user=ErinOTooleMP| number=1274176320352784386 |title=Statement| author=Erin O'Tool |date=20 June 2020}} Later that day, O'Toole filed a formal complaint and requested that the RCMP, OPP, and Toronto Police Service investigate Peter MacKay's campaign and his senior campaign staff member Jamie Lall.{{cite web| url=http://www.theguardian.pe.ca/news/canada/otoole-campaign-asks-police-to-investigate-mackays-campaign-for-allegedly-hacking-internal-data-videos-464505/| title=O'Toole campaign asks police to investigate MacKay's campaign for allegedly hacking internal data, videos| first=Brian| last=Platt| date=19 June 2020| website=theguardian.pe.ca}}

On 20 June, MacKay's campaign dismissed the allegations and called them a "desperate, last ditch strategy" and "mildly amusing."{{cite web| url=https://www.cbc.ca/news/politics/conservative-campaign-theft-accusation-1.5620686| title=Peter MacKay campaign dismisses O'Toole team's theft allegation| first=Teresa| last=Wright| website=cbc.ca}} Lall publicly denied the allegations in a post on his personal Twitter account.{{Cite web|title=Not a single word of this is true|url=https://twitter.com/jamielall/status/1274207238844891136|access-date=23 June 2020|website=Twitter|language=en}}

On 22 June, the National Post reported that the O'Toole campaign received a confession letter from MP staff member implicating Lall and describing him as a "senior regional adviser to the Peter MacKay campaign."{{Cite news|title=O'Toole campaign believes alleged hack came from MP's office, says it has received confession letter|url=https://nationalpost.com/news/politics/otoole-campaign-believes-alleged-hack-originated-in-mps-office|access-date=22 June 2020|newspaper=Nationalpost|language=en-CA}} Later in the day, the RCMP released a statement saying they have begun an investigation into O'Toole's allegations against the MacKay campaign, while Lall stated that he is "aggressively pursuing" legal action against the O'Toole campaign.{{Cite web|date=22 June 2020|title=RCMP probes O'Toole campaign allegation that it was hacked by MacKay campaign|url=https://www.thestar.com/politics/federal/2020/06/22/rcmp-probing-otoole-campaign-allegation-that-it-was-hacked-by-mackay-campaign.html|access-date=23 June 2020|website=thestar.com|language=en}} MacKay spokesperson Chisholm Pothier told CBC News Tuesday that the O'Toole team sent its confidential passwords and logins to more than 300 MPs and their political staff members — something Pothier said was done "negligently and with no reasonable expectation of privacy."{{Cite web|title=MacKay spokesperson says O'Toole team sent its confidential passwords & logins to 300 MPs & their political staffers|url=https://twitter.com/hannahthibedeau/status/1275577441805832194|access-date=25 June 2020|website=Twitter|language=en}} In response, O'Toole campaign manager Fred DeLorey tweeted, "this is a willful attempt at deception. There is a big diff between sending invitees a code for specific meetings and someone breaking into the private admin and stealing all of the files. The former is standard operations, the latter is a crime. That is what is being investigated."{{Cite web|title=This is a willful attempt at deception.|url=https://twitter.com/freddelorey/status/1275610754847252480|access-date=25 June 2020|website=Twitter|language=en}}

On 24 June, an ex-staff member to MP Greg McLean admitted to trying to leak Erin O'Toole's confidential video records, but says the MacKay campaign turned him down, according to Toronto Star's Alex Boutilier and Kieran Leavitt.{{Cite web|title=Breaking: Ex-staffer admits to trying to leak Erin O'Toole's confidential video records, but says the MacKay campaign turned him down.|url=https://twitter.com/alexboutilier/status/1275936682370531328|access-date=25 June 2020|website=Twitter|language=en}} MP McLean later tweeted, "sadly, this is completely inconsistent with what was told to me and senior O'Toole officials by this young man.

He sued the Ontario PC party after narrowly losing an election in November 2018 for party president, but the case has not yet been tried. He is accusing the Ontario PC party of ballot stuffing in that election.{{cite web|url=https://toronto.ctvnews.ca/ontario-pc-member-who-is-suing-party-announces-bid-for-federal-party-leader-1.4786467|title=Ontario PC member who is suing party announces bid for federal party leader|first=Katherine|last=DeClerq|date=28 January 2020|website=Toronto}}
