A leader who cannot win her own seat does not lead for long. Bonnie Crombie lost Mississauga East-Cooksville in the February 2025 snap election, survived a bruising 57% leadership review in September, and finally stepped down on January 14, 2026. The Ontario Liberals won 14 seats under her watch, double their previous count, but none of them was hers.
John Fraser, who had served as interim leader twice before (2018-2020 and 2022-2023), was nominated by the Liberal caucus to fill the role again. He knows where the office supplies are. That he’s been called up three times says something about the party’s talent pipeline.
How It Unravelled
Crombie won the Liberal leadership in December 2023, positioning herself as a fiscally conservative “Blue Grit” on the centre-right of the party. She ran on electability: the Liberals needed a leader who could compete with Ford for moderate suburban voters, and her record as mayor of Mississauga (2014-2023, three consecutive elections with commanding margins) was supposed to be the proof.
As mayor, Crombie championed transit investment, pushed for Mississauga’s LRT, and balanced the city’s budget every year. Good for the resume. The pitch was that municipal competence would translate into provincial credibility, especially in the 905 belt where elections are won and lost. Voters tested that in 2025.
It didn’t hold. The Liberals doubled their seat count from seven to 14 and improved their popular vote share, finishing second overall, but 14 seats in a 124-seat legislature is still a third party. The leader losing her own riding undermined any claim to momentum.
But 14 seats is more than seven. The Liberals picked up ridings across suburban Toronto and southwestern Ontario, including Etobicoke-Lakeshore (Lee Fairclough), Don Valley East (Adil Shamji), and Kingston and the Islands (Ted Hsu). Several wins came in the 905 belt, the ring of suburban municipalities around Toronto that holds roughly 40 of 124 ridings. You cannot win government without the 905. The Liberals’ gains there are a foundation, even if the overall result fell short.
Then came the September 14 leadership review. 57% support. Above the 50% constitutional threshold but well below the 66% many in the party had called for. The threshold question itself became a proxy battle: some riding associations pushed for a two-thirds requirement, arguing that 50% plus one was too low a bar for a leader who had not won her own seat. The party executive kept the 50% threshold. But the fight over the number told you more than the number itself.
Fifty-seven percent is the kind of number that technically means “yes” while clearly meaning “no.”
Crombie held on through the fall. By January the pressure was unsustainable.
Money and Membership
Financially, the party is in better shape than you might expect after the catastrophe of 2018, when it was reduced to seven seats and lost official party status. Fundraising in the 2025 cycle topped $8 million, a significant recovery from the near-insolvency of 2019. Membership numbers have climbed as well, though the party has not released precise figures for 2026: estimates from riding association reports suggest somewhere between 40,000 and 60,000 members provincially. A fraction of the PC membership, but enough to run a competitive leadership race. The next leader will inherit a party with real infrastructure in 14 ridings and credible candidates in a dozen more, which is a very different starting position than the one Crombie inherited.
The Candidates Taking Shape
The leadership vote is scheduled for November 9-20, 2026, with results announced November 21. Several names are circulating, and each represents a different theory of what the party should become.
Nate Erskine-Smith, the federal MP for Beaches-East York and former federal Minister of Housing, finished second in the 2023 leadership race. He has national profile from his housing work and pulls from the progressive urban base. Ted Hsu, MPP for Kingston and the Islands, finished fourth; he’s the policy-focused moderate. Other potential candidates include Lee Fairclough (MPP for Etobicoke-Lakeshore), Adil Shamji (MPP for Don Valley East), Eric Lombardi (housing activist), Josh Matlow (Toronto City Councillor), and Marco Mendicino (former federal Minister of Public Safety).
Mendicino carries federal cabinet experience and federal baggage in roughly equal measure (a description that could apply to half the names on this list).
Left, Right, or Somewhere Else?
Every Liberal leadership race since 2013 has been framed as left versus centre: compete with the NDP for the anti-Ford vote, or peel off moderate PC voters? Same question, different candidates.
The NDP’s weakness (27 seats, vote share below 20%) leaves space on the centre-left, but the Liberals’ own base in suburban Toronto and the 905 has never responded well to left-flank positioning.
Ontario Liberals have rebuilt before. After David Peterson’s surprise loss to Bob Rae’s NDP in 1990, Dalton McGuinty took a decade to climb back to government. After Kathleen Wynne’s devastating loss in 2018 (majority to seven seats), the party needed a full electoral cycle just to regain official party status.
Slow work. Not glamorous. And the temptation to find a shortcut is part of what got the party into trouble in the first place.
Whoever wins gets a party with better finances and more seats than it had three years ago. But Ontario has voted PC three times running.
The 905 belt will be the proving ground. If the next leader can’t build on Crombie’s suburban gains while holding the urban seats, the Liberals are looking at another decade in third place. Nobody in the party wants to say that number out loud.
