Bonnie-Michelle Teresa Bernadette Stack Sawarna Crombie (née Stack, formerly Sawarna; born February 5, 1960) is a Canadian politician and businesswoman who has been the leader of the Ontario Liberal Party since December 2, 2023. On September 14th, 2025, Crombie announced her intention to resign as leader following a poor leadership review result, and will officially step down once a successor is chosen. Crombie previously served as the sixth mayor of Mississauga from December 1, 2014, until January 12, 2024, and 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.
