Water main break on residential street in Laval nearly swallows car

A water main break on Rue Adrien in Laval caused the ground to collapse, forcing road closures and prompting a boil water advisory.

A water main break on Friday in Laval’s St-François neighbourhood on Rue Adrien caused the ground under a parked car to collapse, nearly submerging the vehicle.

A resident, who asked to remain anonymous, shared photos with CTV News showing the car partially sunk into the weakening pavement.

On Sunday, City of Laval crews were still repairing the road, closing a 150-metre stretch of the street.

“Last Friday, our teams were informed of a leak accompanied by subsidence of the roadway on Adrien Street in St-François,” the city said in a statement. “They immediately intervened to secure the area by installing a safety perimeter and began assessing the necessary corrective work, including the condition of gas lines and other underground infrastructure.

“Following this assessment, a team was mobilized today to carry out the required repairs and restore traffic. The water main has been repaired, and work continues to fully restore the area. Residents’ water supply was not interrupted during the work.”

As a precaution, the city has issued a boil water advisory for residents. Crews are still investigating the cause of the leak.
