Mat Siscoe holds a commanding lead in the St. Catharines mayoral market as the incumbent seeking a second term in the October 26 municipal election. His 2022 victory with nearly 69 percent of the vote, built on prior service as city and regional councillor plus roles chairing Niagara Transit and housing boards, underpins trader consensus on his broad base. Four challengers—Anthony A. Adeoye, Ann-Marie Zammit, Jimmy Jackson, and Henry Bosch—registered by the August deadline but lack comparable elected experience or name recognition, with platforms centered on public safety, housing, downtown issues, and infrastructure. The fragmented field has not produced a unified alternative, though any late developments in the final weeks before voting could still shift the outcome in this low-turnout contest.
