The open Thunder Bay mayoral race to replace retiring incumbent Ken Boshcoff remains tightly contested ahead of the October 26 vote, with trader consensus reflecting a crowded field where Moe Comuzzi holds the highest implied probability at 31 percent followed by Trevor Giertuga and Aldo Ruberto. Nominations closed in late August after certification, producing a slate of candidates with overlapping municipal, business, and community experience and no decisive polling data to establish clear frontrunners. Shared local priorities around public safety, housing, infrastructure, and economic development have yet to produce meaningful separation in early campaign activity. Upcoming candidate forums and any release of voter surveys could shift probabilities by highlighting differences on these issues.
