Frank Scarpitti holds a commanding lead in the Markham mayoral race as the long-serving incumbent first elected in 2006 and re-elected multiple times since, giving him extensive municipal governance experience and name recognition across the city. Martin Ross, a first-time challenger known for a high-profile backyard rink dispute with city officials, and Stephen Edgell represent the main opposition in a three-candidate field certified after nominations closed in August. Voting runs online from October 16 to 26, with in-person options later in the period, and early special ballots have already been cast. Trader consensus reflects Scarpitti’s structural advantages in a low-profile municipal contest, though the race remains open until results are certified following the October 26 close. No major late shifts in polling or endorsements have altered the positioning in recent weeks.
