About Bonnie Crombie
Bonnie-Michelle Teresa Bernadette Stack Sawarna Crombie (née Stack, formerly Sawarna; born February 5, 1960) is a Canadian politician and businesswoman who was the sixth mayor of Mississauga from 2014 to 2024 and the leader of the Ontario Liberal Party from 2023 to 2026. Crombie was first elected as the member of Parliament (MP) for Mississauga—Streetsville from 2008 to 2011, sitting as a Liberal. From 2011 to 2014, she held the position of councillor for Ward 5 on Mississauga City Council and was a member of the Peel Regional Council. Crombie was elected as the mayor of Mississauga in the 2014 municipal election. She ran in the 2023 leadership election of the Ontario Liberal Party as a fiscally conservative Blue Grit on the centre-right 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 the 2024 Mississauga mayoral by-election. Following a leadership 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 a successor to be selected at a later date. She won by a margin of slightly over 200 votes, defeating Carolyn Parrish and Eve Adams's ex-husband, Peter. After Hazel McCallion, the long-serving mayor of Mississauga, retired, the 2014 mayoral election became the city's first genuinely competitive race in years.
