Bonnie Crombie, former mayor of Mississauga and current Ontario Liberal Party leader, announced on July 12, 2026 that she will seek the city’s mayoralty in the upcoming election.
Crombie’s declaration follows a brief tenure at the provincial party helm, a role she assumed after resigning as Mississauga’s mayor earlier this year.
During her earlier service as mayor, Crombie oversaw municipal growth and infrastructure projects, establishing a record that she cited when outlining her return to municipal politics.
The announcement positions her as a prominent candidate in a race that will test the Liberal Party’s influence at the local level while offering voters a familiar name with prior executive experience.
City officials confirmed that Crombie has filed the required paperwork with Mississauga’s election office, meeting the statutory deadline for candidacy submissions.
The mayoral contest, slated for later in the year, will feature other local figures, though the field has not been finalized.
During her time as Mississauga’s chief executive, Crombie oversaw initiatives that included expansion of public transit corridors, investment in affordable housing units, and the launch of community safety programs. Those efforts earned her recognition across the Greater Toronto Area and formed part of the platform she intends to build upon in her renewed campaign.
Crombie assumed the leadership of the Ontario Liberal Party in early 2026, succeeding a predecessor who stepped down amid internal reorganization. Her tenure lasted only a few months, during which the party prepared for its next provincial election cycle before she announced her intention to return to municipal office.
