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, the incumbent mayor first elected in 2022 with nearly 69 percent of the vote after multiple terms on city council, holds a commanding lead in trader consensus for the October 26, 2026, St. Catharines mayoral election. His record includes restrained property tax increases, creation of the SCORE nonprofit support fund, and regional roles chairing the Niagara Transit Commission and Niagara Regional Housing Board. Recent challengers Anthony A. Adeoye, Ann-Marie Zammit, Jimmy Jackson, and Henry Bosch registered before the August 21 nomination deadline but bring limited name recognition and no comparable elected experience. Siscoe’s handling of July and August 2026 flooding crises through emergency declarations and infrastructure directives has further reinforced his position, while fragmented opposition has not shifted the broad incumbent base reflected in current market pricing. Late developments or consolidated challengers remain the primary variables that could alter outcomes before election day.
