Keanin Loomis holds a narrow lead in trader consensus for the October 26 Hamilton mayoral election, followed by Rob Cooper and incumbent Andrea Horwath, reflecting a fragmented field of 13 candidates. Loomis, the 2022 runner-up and former chamber executive, campaigns on housing expansion, infrastructure, and accountability reforms, drawing support from voters seeking change after Horwath’s narrow prior victory. Cooper, a sitting councillor, emphasizes tax caps tied to inflation and leverages executive experience in budgeting and safety. Horwath highlights provincial and federal funding secured during her term while facing attacks on city hall performance. Recent debates and final-weekend canvassing have sharpened contrasts on property taxes, crime, and development without shifting the close positioning. Elevated advance voting turnout compared with 2022 could amplify margins depending on ward-level participation and whether late endorsements or turnout patterns favor one challenger over the others.
