Between November 2 and 4, the poll asked 850 voting-age Montrealers about their intentions in the voting booth. Forty-six percent said they planned to vote for Plante. Forty percent planned to vote for Coderre and 5% said they were voting for Holness.
The candidates' support varied among the city's linguistic groups.
Of polled francophones, 55.5% said they would vote for Plante, compared to Coderre's 33.2% support.
The former mayor outpaced Plante among non-francophones, however: 49% support to the current mayor's 35%.
Nine percent of non-francophones said they would vote for Holness. Just 1.8% of francophones supported the Mouvement Montréal leader.
Montreal's election days are November 6 and 7.
