The City of Montreal has issued a boil water advisory for cities on Montreal’s West Island and the Saint-Laurent borough due to maintenance work in the water system.
The City said the advisory affects 200 addresses in Dollard-des-Ormeaux, Dorval, Pointe-Claire, and the borough of Saint-Laurent.
Officials warn that residents in areas affected should boil water for at least one minute before consuming it or using it to brush their teeth.
Non-boiled tap water can only be used when washing dishes in hot water, doing laundry or showering.
Officials say they are currently awaiting the results of the analysis of the water samples, which will confirm the quality of the water and lift the boil water advisory when the parameters are compliant.
The advisory is in effect for an indefinite period.
