The water main break in the area, located off the western tip of the Island of Montreal, has since been contained.
Earlier in the day, residents had to limit their consumption of drinking water to “ensure a minimum supply for essential needs.”
In a statement, the city says water must be boiled for at least one minute before consumption until further notice.
“The notice will be in effect at least until Thursday morning,” the city said.
The advisory is in effect for more than 300 streets in the Vaudreuil sector, including for major arteries such as St-Charles Avenue.
A full list of streets under the boil water advisory can be found on the city’s website.
