“Mark Sutcliffe holds a commanding advantage in Ottawa’s mayoral race among decided voters, securing 49% support compared with 31% for Jeff Leiper. Neil Saravanamuttoo trails at 12%, while Alex Lawson stands at 7%. Among all voters, 23% remain undecided, meaning nearly one in four voters are still up for grabs. Regionally, Sutcliffe leads in Ottawa’s west, east and rural areas, while Leiper holds the advantage in downtown Ottawa.”

CTV News Ottawa/Nanos conducted a RDD dual frame (cell- and land-lines) hybrid random telephone and online survey of 762 residents of Ottawa aged 18 years and over, from October 4th to October 8th, 2026. Respondents were all randomly recruited through a dual-frame (cell- and land-line) RDD sample using live agents. One half of the sample was administered the questionnaire by telephone, and one half was administered online through the Nanos Insights Lab Probability Panel. The random sample was weighted by region, age and gender according to the latest Canadian census data.
A random survey of 762 residents of Ottawa is accurate ±3.6 percentage points, plus or minus, 19 times out of 20.
