Sustainable Development Action Plan 2025-2030

April 9, 2024

Take part in this exercise to learn more about your vision for sustainable development. Then, help us select and prioritize actions for the plan's renewal.


The project to renew the Municipality's Sustainable Development Action Plan (SDAP) aims to assess and improve the environmental, social, and financial impacts of municipal activities. It also aims to strengthen the sustainable development policy and draw up a medium—and long-term action plan for greater sustainability in the future.


The public consultation will be online until May 27, 2024.





UPDATE - MAY 15, 2024

The Municipality has revised the questions in the SDAP consultation following feedback on their complexity. The aim is to enhance clarity and accessibility. The Environment Department is committed to collaborating with residents to realize our vision for the future. We appreciate the responses received thus far and want to clarify that the adjustments made do not impact the prioritization process. All votes submitted prior to the changes will be considered alongside the rest after the consultation. Thank you for your participation.
