Vaudreuil has issued a boil water advisory for many residents.
The city said late Monday that a power failure at its water treatment plant is responsible.
It is warning everyone who lives on these streets to boil their water for at least one minute before drinking, brushing teeth, or washing raw food such as fruits and vegetables.
Anyone with concerns is urged to call the water works department at 450-455-3371 xt. 2600
