Local

Specific to Longueuil

  • No directly elected borough mayors. Borough chairs are chosen indirectly — same model as Québec City. Only Montréal directly elects borough mayors in Québec.
  • Coalition Longueuil sat out Greenfield Park in 2025, formally endorsing Option Greenfield Park's slate — an unusual cross-party arrangement reflecting the borough's anglophone identity.
  • 2024 boundary changes. MAMH approved a new district map adding two districts in Saint-Hubert and one in Vieux-Longueuil, raising council size from 23 to 26 starting with the 2025 election.
  • Voter turnout 2025: ~33%, low even by Québec municipal standards — partly because Fournier's re-election was uncontested in the public mind well before voting day.
  • Agglomération council sits separately and includes the mayors of the 4 demerged cities (Boucherville, Brossard, Saint-Bruno, Saint-Lambert) plus the mairesse of Longueuil and several Longueuil councillors weighted by population.

Ballot

Other roles on the same ballot

Voters in Longueuil also choose:

  • Conseiller / conseillère de district (Ville) — One per electoral district; sits on both city council and the borough council for their arrondissement.
