2025–2029 Strategic Vision (upcoming)

The Council is currently working on the development of the 2025–2029 strategic vision.

Agglomeration Council

The agglomeration council, which came into existence on January 1, 2006, is headed by the mayor of Montréal and consists of 31 elected officials representing all the municipalities on the island of Montréal, specifically:

  • The mayor of Montréal
  • 15 members of Montréal’s city council
  • 14 mayors of reconstituted municipalities (L’Île-Dorval and Dorval have one representative)
  • An additional representative from Dollard-Des Ormeaux (because of the size of its population), selected by the mayor of Dollard-Des Ormeaux.

The agglomeration is structured democratically. The mayor names 15 elected officials to the agglomeration council, who continue their terms as city councillors. The city council determines the direction that elected officials take as part of the agglomeration council. The same goes for mayors of reconstituted cities, whose respective city councils determine the orientations of their work with the agglomeration council.
