Boil-Water Advisory Officially Lifted for Multiple Montreal Municipalities
The City of Montreal has officially terminated a boil-water advisory that had been in place since Sunday afternoon, affecting residents across several West Island municipalities and the borough of St-Laurent. The advisory was lifted on Tuesday evening after water sample tests confirmed that all regulatory standards for drinking water were met.
Affected Areas and Scope of the Advisory
The boil-water advisory impacted approximately 200 addresses in the municipalities of Dollard-des-Ormeaux, Dorval, and Pointe-Claire, as well as the St-Laurent borough. The advisory was necessitated by repair work following a water main break on Avro Avenue, which required temporary precautions to ensure water safety.
Precautionary Measures for Residents
As a precaution, the city is advising affected households to take specific steps to ensure their water systems are fully flushed and safe for use:
- Turn on all cold water faucets and let the water run for a few minutes before using it.
- Perform the same flushing process for outdoor taps, water hoses, and drinking fountains.
- Empty, wash, and disinfect coffee makers and ice machines.
- Change water filters in any water treatment or filtration systems, including pitchers, refrigerator water dispensers, faucet filters, or under-sink filters.
Note: Hot water tanks do not need to be emptied as part of these precautions.
Official Statements and Next Steps
In a press statement, the city confirmed that the advisory, which had been in effect since March 1, 2026, is no longer necessary. "Montreal has obtained confirmation that all regulatory standards pertaining to drinking water are met," the statement read. "It is therefore no longer necessary to boil water before consuming it in the formerly affected areas."
