2021-2025 Strategic vision

Council is pleased to present the municipality’s strategic vision for this Council’s mandate (2021-2025).

The mission statement and four orientations supporting it are the result of feedback received by our elected members during their recent election campaign, as well as input from citizens during the public consultation on recreation in 2020.

We believe that this vision for the coming four years builds on our history and our extraordinary setting while recognizing the challenges we are facing due to climate change.

This strategic plan will guide Council and the administration in prioritizing projects and interventions on our territory while being fiscally responsible.


Building on our natural and architectural heritage, and supported by our civic involvement, Senneville seeks to provide a respectful and safe community life to its citizens, through transparent and accountable management.


1. Heritage – Protect our landscape and built heritage

Through relevant initiatives, we will ensure that the Village of Senneville’s unique character is preserved both from a landscape and an architectural perspective. This will involve improving the awareness tools citizens can use to learn about our urban planning by-laws, by-law enforcement, and documenting Senneville’s rich history.

2. Environment – Protect our Eco-territory and upgrade our infrastructure

Our aim is to protect the Eco-territory of the Senneville Forest through acquisition, tree planting and maintenance while minimizing our environmental footprint and modernizing our municipal infrastructure to provide a healthy and safe environment to our citizens.

3. Community Life – Promote inclusivity and participation by all citizens

As community life is a strong characteristic of Senneville living, we will work to promote and improve quality of life by restoring and adding parks and recreational spaces while supporting and/or reviving recreational programs for citizens of all ages.  Communications with citizens will continue to be a high priority. 

4. Mobility – Provide a secure road network and increase public transit services

We will help citizens move safely within and beyond the community through investment in road networks for all travellers—drivers, cyclists, and pedestrians, as well as users of public transportation options.

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.
