Flooding | Update as of April 21
Overall Situation
Following reports of rising water levels, the Organisation municipale de sécurité civile of Ville de Vaudreuil-Dorion (OMSC)
has stepped up its response efforts to protect certain infrastructure. This development comes despite forecast data from the past few days, which had indicated that water levels were stabilizing.
A levee will be installed within the next 24 hours along sections of Saint-Charles Avenue and Chemin des Chenaux. As a preventive measure, infrastructure—including sewer access manholes and pumping stations—will be protected to limit the impact of a potential rise in water levels.
At this time, the situation in Vaudreuil-Dorion remains under control, but it is being constantly monitored.
The Service de sécurité incendie is maintaining a constant watch and conducting regular patrols in areas deemed at risk.
Guidelines for the public
Residents are urged to remain vigilant, particularly in areas along the river, and to monitor the situation closely. It is recommended that you secure your belongings in at-risk areas and ensure that your home’s water pumps are in working order. Any concerns should be reported to municipal authorities.
Closures
- A section of Rue de Breslay, which runs parallel to Highway 40, is closed.
- The Esther-Blondin Pier is closed to the public.
- The road leading to Maison-Valois Park is closed.

However, these forecasts involve a degree of uncertainty and are provided for informational purposes only.
Self-service sand stations
In light of the rising water levels, the City is providing self-service sand stations to help residents protect their property.
Sandbag filling stations are now available. Facilities have been set up on-site to make filling the bags easier.
Important: Residents must bring their own shovel.
Station locations
Two sites are currently available:
- 190 Saint-Charles Avenue, at the corner of Hôtel-de-Ville Street (Vieux-Dorion neighborhood)
- Corner of Breslay Street and Chenaux Road
These locations were selected based on their accessibility and the available space to ensure smooth and safe traffic flow.
