The 2026 Ottawa 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 Ottawa 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 Ottawa.Incumbent Mayor Mark Sutcliffe holds a commanding 62.5% implied probability on prediction markets for the October 26 Ottawa mayoral election, bolstered by strong name recognition, fundraising advantages, and a fragmented opposition echoing his 2022 victory. Recent Liaison Strategies polling from April 12 showed him leading decided voters 46% to Jeff Leiper's 37% and Alex Lawson's 13%, with roughly half undecided amid low approval ratings on transit (30% approve), crime, and $419 million Lansdowne 2.0 spending (62% disapprove). Housing affordability and public transit dominate voter concerns, yet challengers like Kitchissippi Councillor's Leiper and homebuilder Lawson split anti-incumbent votes. Nomination filings open today (May 1), with the formal campaign period starting September 1.
