Bonnie-Michelle Teresa Bernadette Stack Sawarna Crombie[1] (néeStack, formerlySawarna;[2] born February 5, 1960) is a Canadian politician and businesswoman who was the sixthmayor of Mississauga from 2014 to 2024 and the leader of theOntario Liberal Party from 2023 to 2026.
Crombie was first elected as themember of Parliament (MP) forMississauga—Streetsville from 2008 to 2011, sitting as aLiberal. From 2011 to 2014, she held the position of councillor forWard 5 on Mississauga City Council and was a member of thePeel Regional Council. Crombie was elected as the mayor of Mississauga in the2014 municipal election.
She ran in the2023 leadership election of the Ontario Liberal Party as afiscally conservative[3]Blue Grit[4] on thecentre-right[5] flank of the party, and won on the third ballot over her more left-leaning rivals. She resigned as mayor on January 12, 2024, in order to focus on her leadership of the Ontario Liberal Party, triggering the2024 Mississauga mayoral by-election. Following aleadership review in September 2025 in which she received only 57% support, Crombie announced her resignation as leader and formally stepped down on January 14, 2026, with asuccessor to be selected at a later date.
Bonnie-Michelle Teresa Bernadette Stack[1] was born on February 5, 1960, to Polish immigrants Veronica Sawarna (née Sega) and Ed Stack inToronto, Ontario. When Bonnie was three, her parents separated, and she and her mother relocated to her grandparents' large home in Toronto'sHigh Park neighbourhood.[6]
When Crombie was nine, her mother remarried to Michael Sawarna, who adopted Bonnie, and she took his surname, becoming Bonnie-Michelle Teresa Bernadette Stack Sawarna. The family settled inEtobicoke, where Crombie attendedMichael Power/St. Joseph High School.[6][7] Crombie describes her late stepfather as a “solid, hard-working, decent, honest man, and a churchgoer. We became very close. He was my father.”[6]
In 1982, she graduated fromSt. Michael's College at theUniversity of Toronto with aBachelor of Arts inpolitical science andinternational relations. Later, in 1992, she earned herMaster of Business Administration from theSchulich School of Business.[6]
Before venturing into politics, Crombie worked as a marketing manager forMcDonald's Canada andthe Walt Disney Company and later worked as manager of government relations for theInsurance Bureau of Canada.[8]
She married Brian Crombie, former-CFO ofBiovail Corp. and theOttawa Senators,[9][10][11] in 1984, with whom she has three children: Alex, Jonathan and Natasha.[6] The couple divorced in 2020.[12]

Crombie was elected as the MP forMississauga—Streetsville in the2008 Canadian federal election, defeating incumbent MPWajid Khan, who had previouslycrossed the floor from theLiberal Party to join theConservative Party.[13]
Following her election, she served as co-chair of the Liberal Caucus Outreach Committee alongsideJustin Trudeau[14] and took on the role of the Liberal Party critic for Crown corporations under leaderMichael Ignatieff.[15]
In the2011 federal election, Crombie was defeated by Conservative candidateBrad Butt; Butt received 43.8% of the vote to Crombie's 36.9%.[16]
On September 19, 2011, Crombie secured a seat onMississauga City Council through a by-election, succeedingEve Adams as councillor forWard 5. She won by a margin of slightly over 200 votes, defeatingCarolyn Parrish and Eve Adams's ex-husband, Peter.[17] On December 12, 2012, Crombie faced charges related to alleged violations of election finance rules from her councillor run,[18] but these charges were withdrawn in February 2013 after the Crown determined that financials needed formal auditing before any charges could be considered.[19]
AfterHazel McCallion, the long-serving mayor of Mississauga, retired, the2014 mayoral election became the city's first genuinely competitive race in years.[20] Crombie, along with former member of both provincial and federal parliamentsSteve Mahoney and others, declared their candidacies.[21] Despite Mahoney's narrow lead in polls for much of 2014, McCallion's endorsement of Crombie on October 12 shifted the dynamics, giving Crombie a 25-point lead over Mahoney.[22][23] In the election, Crombie secured victory with 63.5 per cent of the vote.[24]

Crombie announced her bid for re-election as mayor on October 27, 2017[25] and emerged victorious in the2018 mayoral election with 77 per cent of the vote.[26] She secured her third term in the2022 mayoral election by another wide margin.[27][28]
Throughout her mayoral tenure, Crombie advocated for the dissolution of theRegion of Peel, the upper-tier municipality of which Mississauga is part.[29] In 2023, the provincial government ofDoug Ford supported the split.[30][31]
During a Liberal leadership debate onThe Agenda with Steve Paikin, hosted by TVO on November 15, 2023, Crombie declared that she would not seek re-election in 2026, concluding her tenure as the mayor of Mississauga after three terms. She later stated that she was likely to run forMPP in the2025 provincial election.[32]
After winning the2023 leadership election of the Ontario Liberal Party, Crombie announced on December 13 that she would resign as Mississauga mayor, effective January 12, 2024, after completing the city's and Peel Region's budgets before stepping down.[33][34] She was succeeded as mayor byCarolyn Parrish.[35]
In early 2023, media reports, citing sources within the party, speculated that Crombie was contemplating a run in the 2023 Ontario Liberal Party leadership election scheduled for December. Her active participation was noted during theOntario Liberal Party's annual general meeting in March 2023 and theLiberal Party of Canada's national convention in May 2023 in Ottawa.[36][37][38]
On May 23, 2023, Crombie confirmed the speculation by announcing the formation of an exploratory committee.[39] On June 14, she officially launched her campaign at an event in Mississauga.[40] She took an unpaid leave of absence from her role as mayor of Mississauga starting October 7.[41] However, she returned on November 27 to participate in the city's budget process.[42]
Crombie was considered the front-runner in the Liberal leadership race.[43][44] She ran on a pledge to make life more affordable, strengthen Ontario's healthcare system, build housing and infrastructure, improving the public education system, and fighting climate change.[45] During the race she referred to herself a "a very centrist person", "very fiscally responsible", and "socially very progressive".[46] She was elected party leader at the December 2, 2023, on the third ballot.[47] She resigned as mayor on January 12, 2024.[48][49]
Following the resignation ofParm Gill from theOntario Legislature in January 2024, Crombie stated that she was considering running in the resultingMilton by-election,[50] but later decided not to seek the seat.[51]
Crombie announced on March 18, 2024, that if she became premier after the2025 election, she would refrain from implementing a provincialcarbon tax as part of her climate policy,[52][53] diverging from the approach of Prime MinisterJustin Trudeau and the federal Liberals.[54] The next day, she declined to comment on a proposed federal carbon tax supported by the Liberal Party of Canada, saying "I'm not here to tell the federal government how to do their job."[55]

On August 21, 2024, theOntario Liberal Party announced their keynote speakers for their annual general meeting that included former British Columbia PremierChristy Clark and former Canadian Health MinisterJane Philpott. This move was seen by many as another attempt to distance the party and its leader from Trudeau and the federal Liberals.[56][57]
On September 21, 2024, Crombie and the Ontario Liberal Party unveiled their new logo alongside their slogan, "More for You".[58]
On December 3, 2024, Crombie criticized the federal carbon tax, describing it as "wrong."[59]
Crombie led the Liberals to a third-place finish in the2025 Ontario general election. While the party picked up enough seats to regainofficial party status for the first time since 2018, the gains were not enough to displace theOntario NDP asofficial opposition. Crombie also failed to win a seat in the Ontario legislature, placing second inMississauga East—Cooksville.[60] Nevertheless, she vowed to continue as Liberal leader.[61][62] On March 1, 2025, the Ontario Liberal Party's executive council voted unanimously in support of Bonnie Crombie remaining party leader.[63]
Crombie received 57% support in a leadership review vote during the party's annual general meeting. This was above the 50% support required by the party's constitution, but short of the 66% many in the party had been calling for.[64][65][66] Crombie initially announced that she would be staying on as leader, but hours after the results were announced issued a statement that she planned to resign upon theselection of a new leader.[67][68] She formally resigned as leader on January 14, 2026, with a successor to be chosen at a later date.[69] Crombie is said to be considering a bid to run for mayor of Mississauga again in the 2026 municipal election, stating "all options are on the table".[70]
