MONTREAL—After two hours of screaming water hoses, a five-alarm fire was still burning at the corner of Bellechasse St. and St-Denis Blvd. on Thursday afternoon.

First reported at 1:52 p.m., over 125 firefighters responded to the blaze tearing through the three-storey building. While the fire was nearly under control by 4:22 p.m. five people were left homeless by the flames.

The building was attached on one side to a commercial building that housed a dental clinic—14 people had to be evacuated from the clinic.

While a cause for the fire has yet to be determined, firefighters say the flames started in the back of the building.

No one was injured.
