The 2020 Ontario Liberal Party leadership election concluded on March 7, 2020, resulting in the election of Steven Del Duca, a former cabinet minister in the government of Kathleen Wynne, as Ontario Liberal Party’s 33rd leader.
The leadership election took place following the resignation of Kathleen Wynne after over five years at the helm of the party. Her resignation took place on the evening of June 7, 2018, after the majority government led by her was defeated in the 2018 election and the party lost official party status.
The leadership election featured six candidates: former cabinet ministers Del Duca, Michael Coteau, and Mitzie Hunter, former provincial election candidates Kate Graham and Alvin Tedjo, and political newcomer Brenda Hollingsworth. The election was concluded with a delegated convention that took place March 6–7, 2020 at the International Centre in Mississauga.
Background.
Lead up to the 2018 Election.
After securing an upset leadership victory in 2013, Kathleen Wynne won a fourth consecutive mandate for the Ontario Liberal Party in June 2014 by marketing herself as a fresh face for the Liberals who would distance the party from Dalton McGuinty. However, the Liberals' standing with voters was badly hurt when Wynne’s government partially privatized Hydro One in 2015, after campaigning against it in the 2014 election, as well as rising criticism over "ballooning provincial debt, high electricity prices and costly, politically expedient decisions". The party headed into the 2018 election campaign trailing far behind the Progressive Conservatives. In the two years leading up to the 2018 campaign, the Liberals trailed the Progressive Conservatives in all but three of the more than eighty opinion polls published. 
With the party’s electoral fortune declining, there were public calls for Wynne’s resignation as early as spring 2017, most notably from former finance minister and campaign chair Greg Sorbara (under whom Wynne served as campaign vice-chair in 2011). Wynne consistently resisted the calls. Throughout the 2018 election campaign, the Liberals polled consistently in third place behind not only the Progressive Conservatives but also the New Democrats. CBC’s poll tracker projected zero to two seats (out of 124) for the Liberals at multiple points of the election campaign. 
At the conclusion of the campaign, the Liberals elected only seven MPPs, losing official party status in the Legislature. It was the worst electoral result in the party's 161-year history and the worst result for any incumbent governing party in Ontario. On the night of the election, Wynne announced her resignation as party leader, while continuing to sit in the legislature as MPP for Don Valley West.
Interim leader.
Wynne announced on election night that she had asked the party president to begin the process of choosing an interim leader. According to the party's constitution, an interim leader is to be selected by a vote of the party caucus, the presidents of riding associations without an elected Liberal MPPs and party executive members. With four of the remaining seven caucus members actively contemplating leadership bids, one being in poor health, and one being the outgoing leader, the Liberal caucus quickly endorsed the seventh member, Ottawa South MPP John Fraser, to serve as interim leader on June 13, 2018. Fraser assumed the office of interim leader on June 14, following a ratification vote of party executives and presidents of riding associations for the remaining 117 ridings that do not have a Liberal MPP.
Rules and procedures.
Under the procedure outlined by the party's constitution, all members of the Ontario Liberal Party are eligible to cast a two-part ballot at one of the "Leadership Election Meetings" held across the province. Members vote directly for their choice of leadership candidate (or for "independent") in the top part of the ballot, and for local delegates for the leadership convention in the bottom part of the ballot. Elected delegates were apportioned to leadership candidates based on their share of votes in the top part of the ballot, and are bounded to vote for their leadership candidates on the first ballot at the leadership convention. The small number of independent delegates elected can vote for whomever they chose at the convention.
The delegates of the leadership convention made up of approximately 2000 elected delegates (16 delegates elected by members from each of the 124 electoral districts, 8 delegates from each Ontario Young Liberals campus clubs, 1 delegate from each Ontario Women Liberals Commission clubs) and more than 500 ex-officio delegates (by virtue of party and elected offices they have held, such as sitting and former Liberal MPPs, recent provincial Liberal candidates, sitting federal Liberal MPs, and various party officials and representatives of party bodies). Balloting at convention continues until one candidate receives a majority of ballots cast.
At the party's Annual General Meeting held on June 8, 2019, an organized attempt was made to amend the party constitution to change the leadership election system to eliminate the delegated convention and adopted a weighted One Member One Vote point system similar to the ones used by the Progressive Conservatives and the federal Liberal Party. The amendment was supported by 57% of delegates, but failed to receive the two-thirds majority required for it to pass.
The 2020 leadership election marked the last time that this system was used, as a weighted one member one vote point system was adopted by the party in 2023.
Leadership Campaign.
Early campaigning.
Given the weak polling numbers during the final years of the Wynne government, there was frequent chatter about the leadership aspirations of various cabinet members and MPPs. The names most frequently discussed were of finance minister Charles Sousa, health minister Eric Hoskins (both 2013 leadership contenders), Attorney General Yasir Naqvi (party president at the time of the 2013 leadership election), transport minister Steven Del Duca (co-chair of the 2013 leadership convention), and backbench MPP Yvan Baker.
With Sousa, Del Duca, Naqvi and Baker all losing their seats and Hoskins leaving provincial politics, the likely slate of candidates became uncertain after the 2018 election. In the latter half of 2018, four former ministers who survived the election, Michael Coteau, Mitzie Hunter, Marie-France Lalonde, and Nathalie Des Rosiers, actively explored their candidacies, while the candidacies of Del Duca, Naqvi, and Baker continued to be frequently speculated. Baker and Lalonde later opted to seek federal seats (both successful). Des Rosiers left politics to become principal of Massey College, while Naqvi became CEO of Institute for Canadian Citizenship. Del Duca briefly sought the chair-ship of York Region until the election was cancelled by the Ford government. Adam Vaughan and Mark Holland, two relatively high-profile MPs, both publicly acknowledged that they contemplated and subsequently ruled out bids, opting to seek re-election federally.
Formal campaign.
On April 3, 2019, Del Duca formally declared his candidacy, the first candidate to do so. This was prior to the party’s annual general meeting in June where amendment proposals to the leadership rules were being debated. Del Duca refrained from taking positions on any of the amendment proposals, citing perceived conflict of interests. Alvin Tedjo, a former political aide and provincial election candidate, declared his candidacy in late May. An organized “draft Chris Hadfield” movement was present at the party’s annual meeting, even though the former astronaut at no point expressed any inclination to enter politics. 
Following the annual meeting, the party announced that it would formally “call” the leadership contest (a legal requirement imposed by the legislation) on July 18, 2019, that candidate registration deadline would be on November 25, 2019, and that the contest would conclude at a convention on March 7, 2020. It also announced an entrance fee of $100,000 (including $25,000 refundable deposit) and a spending limit of $900,000. 
Coteau announced his candidacy soon after the party’s annual meeting in June, while Hunter formally joined the race in early August. Kate Graham, a university instructor and former provincial election candidate, joined the race in September. Kyle Peterson, outgoing MP for Newmarket-Aurora, and Arthur Potts, a former MPP, both commenced bids in the fall of 2019, but ended their bids prior to formally launching their campaigns. Ottawa lawyer Brenda Hollingsworth, a political newcomer, joined the race on the registration deadline, rounding out the field of six. 
The party organized six debates among the candidates, held in Guelph (December 8), Windsor (December 12), Ottawa (January 20), Sudbury (January 30), Markham (February 1) and Toronto (February 24). All six debates were livestreamed on the party’s website. In addition, the Empire Club of Canada hosted a debate on January 15, and TVO hosted a televised debate on February 19.
The party imposed membership cut-off for voting eligibility for December 2, 2019. At the cut-off, Del Duca claimed to have recruited 14,173 members while Coteau, Hunter and Tedjo claimed 8500, 2000 and 1000 respectively. The party later disclosed that 37,831 members in total were eligible to vote. 
Del Duca was seen as the frontrunner throughout the campaign. It was generally agreed that he had the most robust ground organization and most experienced campaign team. He also received by-far the largest share of endorsements from elected and party officials, with more public endorsements from former and current MPPs and MPs than the other five candidates combined. Coteau, with the longest tenure in the legislature and cabinet, pitched himself as the primary rival to Del Duca, and was generally viewed as seeking to reform the party. Graham, a political newcomer who campaigned to “change how we do politics”, also put forward a competitive campaign with the endorsements of former Deputy Premier Deb Matthews and a number other prominent figures seen as close to Wynne.
Del Duca’s frontrunner status was cemented after the February 8–9, 2020 weekend, during which party members throughout the province voted at local leadership election meetings. Del Duca earned over 55% of the elected delegates, won the most votes in 89 of 124 ridings, and led delegate counts in all regions of the province. Coteau was in second, with Graham a distant third place, earning 18% and 13% of the delegate respectively. With strong second place showing in Southwestern Ontario (which voted on Saturday of the weekend), Graham actually led Coteau on delegate count after the first day of voting. Coteau re-gained second place by the end of the weekend, with stronger showing in Toronto and Eastern Ontario (which voted on Sunday).
Despite the outcome of the leadership election being a virtual certainty leading up to the convention, about 3,000 people attended the two-day event, co-chaired by Deputy Prime Minister Chrystia Freeland and interim leader John Fraser. On March 7, 2020, Del Duca was formally elected leader on the first ballot with 59% of the ballot cast.
