Montréal lifts boil-water advisory on parts of three Plateau streets

Montréal has lifted a precautionary boil-water advisory for parts of three streets in Le Plateau-Mont-Royal. The city says people at the affected addresses can drink the tap water without boiling it.

The notice covers Aylmer Street from Prince-Arthur Street West to Avenue des Pins, the north side of Prince-Arthur Street West from Aylmer to University Street, and Lorne-Crescent Street from Prince-Arthur to the dead end.

The city advises residents to run cold-water taps for a few minutes, flush outdoor taps and empty, clean and disinfect ice makers. If you use a water-treatment device, check the manufacturer’s instructions.
