Mark Sutcliffe’s commanding position in the Ottawa mayoral race stems from his incumbency, recent polling showing a substantial lead among decided voters, and broad cross-party endorsements including from former Prime Minister Jean Chrétien. A Nanos survey conducted October 4–8 found him at 49 percent support versus 31 percent for closest rival Jeff Leiper, with 23 percent undecided two weeks before the October 26 vote. Sutcliffe has emphasized affordability measures, infrastructure investment, homelessness reduction targets, and tax restraint while securing federal funding commitments. Remaining uncertainty centers on how undecided voters break and the impact of the October 14 mayoral debate, though no late developments have yet narrowed the gap reflected in current trader consensus.
