Steven Del Duca, the incumbent Vaughan mayor first elected in 2022, holds an overwhelming lead in trader consensus due to his established record on local priorities including a 0% municipal property tax increase, reduced development charges to support housing, infrastructure expansions addressing traffic congestion, and public safety initiatives. Nominations closed in August 2026 with only two certified mayoral candidates on the ballot for the October 26 election: Del Duca and challenger Shelly-Ann Starlette Cerrelli, whose late entry has not shifted market positioning. Minor candidates register negligible implied probabilities. Upcoming advance voting from October 9-18 and the short remaining campaign window reinforce the current trader assessment of limited contestation.
