A by-election for the seat of University—Rosedale, Ontario in the House of Commons of Canada is currently scheduled to be held on April 13, 2026. This market will resolve according to the candidate who wins the by-election for the University—Rosedale, Ontario seat in the House of Commons of Canada. If the results of this by-election are not definitively known by March 31, 2027, 11:59 PM ET, this market will resolve to “Other”. The resolution source for this market will be a consensus of credible reporting. In case of ambiguity, this market will resolve solely based on the official election results published by the Canadian government, specifically Elections Canada (https://www.elections.ca/home.aspx).In the University—Rosedale federal by-election scheduled for April 13, Liberal candidate Danielle Martin commands trader consensus at 99.3% implied probability, driven by the riding's status as a longtime Liberal stronghold where the party captured 64% of the vote in the 2025 general election amid urban Toronto demographics favoring progressives. Martin's profile as a University of Toronto family medicine professor and health care leader, bolstered by Prime Minister Mark Carney's endorsement on April 4, strengthens her position against fragmented opposition including Conservative Don Hodgson and NDP's Serena Purdy. Advance polls opened April 3 amid active campaigning, with low by-election turnout typically benefiting the incumbent party. Upsets would require a late scandal, health issue, or improbable Conservative surge in this safe seat.
