Bonnie Crombie holds a narrow lead in the Mississauga mayoral race according to the latest October polls, reflecting her prior experience as mayor and recent gains amid voter concerns over affordability, property taxes, housing, transit, and public safety. The contest remains tight among Crombie, incumbent Carolyn Parrish, and councillor Alvin Tedjo, with Dipika Damerla trailing, as multiple surveys show shifts of just a few points and persistent undecided voters. Record advance turnout signals strong engagement that could hinge on get-out-the-vote operations and demographic patterns, such as gender and age splits. Scheduled for October 26, the outcome may turn on final campaign messaging around tax relief and regional services, or last-minute turnout in key wards, keeping implied probabilities close until polls close.
