2017 Montreal municipal election

Municipal elections were held in the city of Montreal, Quebec, Canada on November 5, 2017 as part of the 2017 Quebec municipal elections. Voters elected 65 positions on the Montreal City Council, including the mayor, borough mayors, and city councillors, as well as 38 borough councillors.

Results


Despite early polls giving incumbent mayor Denis Coderre a comfortable lead, the election concluded with Valérie Plante of Projet Montréal winning the mayoralty race by a margin of over 27,000 votes, becoming the first woman and first representative of Projet Montréal to be elected mayor of Montreal. Her party won a majority of the city council, 34 of 65 councillors.

Projet Montréal won unanimous control of four borough councils and majorities on seven more. Équipe Denis Coderre pour Montréal won unanimous control of four borough councils and majorities on two more. The two remaining boroughs, Anjou and LaSalle, were won unanimously by local parties, Équipe Anjou and Équipe Barbe Team respectively.

Several key city council figures were defeated, such as Russell Copeman, Harout Chitilian, Claude Dauphin, Anie Samson, Réal Ménard and Elsie Lefebvre. Projet Montréal founder Richard Bergeron, who had crossed the floor to Équipe Coderre, was defeated by the candidate for his former party, Robert Beaudry.

Following his defeat, Denis Coderre announced he would resign from political life, leaving his city council seat to his co-candidate Chantal Rossi. On November 9, members of his party elected Darlington councillor Lionel Perez as leader; it was also announced that the party, named for Coderre, would change name in the coming weeks.

Coalition Montréal was left with only one remaining elected official, Montreal's longest-serving city councillor Marvin Rotrand. Vrai changement pour Montréal, which had come in second in the mayoralty race in the previous election, lost all its seats, and announced it would suspend its activities.

For the first time, a majority of Montreal's elected officials (53 out of 103) were women. Six of the 103 elected officials (5.8%), including four of the 65 members of the city council, declared themselves to be members of visible minorities. Visible minorities make up a third of the population of the city. Another elected official, Champlain–L'Île-des-Soeurs city councillor Marie-Josée Parent, who is of Mi'kmaq ancestry, became the first indigenous person elected to Montreal city council.

The official results were released on November 8, 2017. There was one request for a recount, in the race for borough councillor for La Pointe-des-Prairies in Rivière-des-Prairies–Pointe-aux-Trembles, in which Lisa Christensen of Projet Montréal had been announced as the winner with a lead of 32 votes. The recount was conducted by a judge of the Court of Quebec and Ms. Christensen was confirmed as the winner by a majority of 30 votes.
