Water gushed out of a water main early Saturday morning, flooding the intersection of St-Joseph and Berri streets.
The water has filtered down to Mont-Royal Avenue and even Marianne Street, leading Montreal police to shut down both St-Joseph and Mont-Royal between Berri and Boyer.
Because of the freezing cold temperatures, blue-collar workers with the city are on the scene trying to spread abrasives and clear the snow off manhole grates to prevent the water from turning to ice.
Conditions may be dangerous on St-Joseph Street and Mont-Royal Avenue, as well as streets adjacent to them.
Some streets could remain closed for the entire weekend while the city cleans up and works to repair the burst pipe.
