In 2025, Saint‑Laurent and the Ville de Montréal completed numerous projects affecting more than 60 street segments. Work focused mainly on water and sewer rehabilitation (11 segments), roadway resurfacing (7 segments) and full street reconstruction (2 segments). 

At the local level, Saint‑Laurent also carried out sidewalk reconstruction on more than 15 segments, as well as work in several alleyways. The year was also marked by significant investments in public lighting and electrification, as well as major park projects. 

All of these initiatives are part of an approach focused on asset maintenance and on improving safety, mobility and quality of life.
