A little after noon on January 22, officials issued a boil water for part of Montreal's Ville-Marie borough.
The "preventative measure" comes after a 24-inch water pipe broke on rue DeLorimier between rues Roy and Larivière.

The advisory is in effect for an undetermined amount of time.
The affected area is highlighted in an online map. It's located between rue Ontario, rue Sherbrooke, rue de Champlain and the Canadian Pacific rails at the eastern end of the borough.
Residents of this area are instructed to boil their water for one minute before drinking it or using it to brush their teeth.
They can still use the water for "personal hygiene or other domestic purposes," according to a statement from the city.
Montreal notes that "boiled water will keep for 3 days in the refrigerator and 24 hours at room temperature."
The city will issue a notice to residents as soon as the water is safe to consume without boiling.
Once the advisory is lifted, the city advises that residents "open all cold water taps and let the water run for a few minutes before using it to allow the pipe to drain completely."
