Laval launches major project to stabilize Boulevard des Mille-Îles
The City of Laval has announced a major infrastructure project aimed at stabilizing sections of Boulevard des Mille-Îles following multiple landslides recorded in recent years along the riverfront corridor.
According to information released May 13, the project will benefit from a $25 million financial contribution from the Government of Canada, while the total cost of the various phases is estimated at more than $80 million.
City officials say the work is intended to improve the long-term resilience of the roadway against erosion and extreme weather events linked to climate change.
A response to repeated landslides
Over the past several years, more than a dozen landslides have been reported along parts of Boulevard des Mille-Îles, leading at times to partial or complete road closures and emergency interventions.
The City states that erosion, ice movement, freeze-thaw cycles and heavy rainfall have contributed to the deterioration of riverbank sections bordering the roadway.
Mayor Stéphane Boyer described the boulevard as one of Laval’s historic roadways and said the project marks a transition from reactive emergency repairs toward a long-term stabilization strategy.
Federal support for climate adaptation
Federal MP Angelo Iacono, representing Alfred-Pellan, said the investment is intended to help protect residents and infrastructure from the impacts of climate change while preserving the surrounding natural environment.
The project will cover approximately 9.5 kilometres, stretching between Autoroute 25 and the eastern tip of Île Jésus. According to the City, more than 7 kilometres of riverbank slopes will be stabilized as part of the work.
Protecting a heritage and ecological corridor
The boulevard runs alongside a recognized ecological corridor known for its biodiversity and historic character. The area also contains several heritage buildings that Laval says it intends to preserve and highlight during the redevelopment process.
The route is widely used by cyclists and pedestrians and is considered one of Laval’s most popular waterfront corridors for active transportation.
City officials say the project will include new pedestrian and cycling-friendly infrastructure designed to improve safety and accessibility in the sector.
Construction expected to begin in 2027
Environmental studies and technical planning are currently underway as Laval seeks the necessary government authorizations.
The first construction phases are expected to begin in 2027, with the overall project projected to unfold over approximately six years. According to the City, the work will be completed in phases to reduce impacts on traffic and nearby residents.
