Mark Sutcliffe maintains a clear lead in the Ottawa mayoral race as the incumbent, consistent with July 2026 polling showing him at 36% among decided and leaning voters compared to Alex Lawson at 26% and Jeff Leiper at 25%, with 34% undecided. Traders appear to price in Sutcliffe’s structural advantages, including name recognition and early consolidation of moderate support, even as his overall approval has softened amid debates over transit, housing costs, and infrastructure like a potential ring road. Leiper, a sitting councillor with a transit-focused platform and prior endorsement from Catherine McKenney, and Lawson, a homebuilder emphasizing development approvals, trail as the opposition remains divided without a single frontrunner emerging to challenge the mayor directly. Nominations closed shortly after the current date, setting up the October 26 vote with limited time for major shifts.
