The 2026 St. Catharines, Ontario mayoral election is currently scheduled to be held on October 26, 2026. This market will resolve according to the candidate who becomes the next mayor of St. Catharines, Ontario as a result of this election. Temporary, interim, or placeholder mayors appointed before the election will not be considered. If the result of this election isn't known by June 30, 2027, 11:59 PM ET, the market will resolve to "Other". The primary resolution source for this market will be a consensus of credible reporting; however, if there is any ambiguity in the results, this market will resolve according to official information from St. Catharines, Ontario.Mat Siscoe maintains a commanding lead in the St. Catharines mayoral market as the incumbent seeking a second term in the October 26, 2026 election. His prior victory with nearly 69 percent of the vote in 2022, combined with multiple terms on city council and regional roles including chair of the Niagara Transit Commission, underpins trader consensus around his position. Recent actions such as directing flood resilience reviews after heavy summer rainfall and maintaining restrained property tax policies have reinforced his record without significant shifts in the field. The remaining candidates, including Anthony A. Adeoye, Ann-Marie Zammit, Jimmy Jackson, and Henry Bosch, registered before the August nomination deadline but hold limited prior elected experience or comparable visibility. Late developments such as unexpected turnout changes or coordinated challenger momentum ahead of election day represent the primary scenarios that could narrow the gap.
