The Thunder Bay mayoral contest remains tightly contested ahead of the October 26 vote because an open seat has drawn a crowded field of ten candidates with varied municipal, business, and community experience. Recent local polling and candidate forums show the top contenders—current at-large councillor Trevor Giertuga, business leader Moe Comuzzi, and former councillor Aldo Ruberto—trading narrow leads as voters weigh priorities such as housing approvals, public safety, economic development, and infrastructure. Trader pricing reflects this fragmentation, with no single contender securing a decisive edge. Further candidate debates, advance voting starting October 19, or last-minute shifts in turnout among key wards could consolidate support and widen gaps before ballots close.
