Firefighters are battling a five-alarm fire that broke out in Verdun.
The fire started at around 7 a.m., according to Service de sécurité incendie de Montréal, in the third floor of an apartment building located on 6th Avenue.
Flames quickly spread to the roof and into three neighboring buildings, forcing around 100 people out of their homes.
Thirty six apartments are affected. No cause has been determined but officials do not suspect criminal wrong doing.
Luc Robillard, chief of operations with the Montreal fire department, says the crumbling state of the roof made it harder for crews to operate. Four firefighters fell from the roof three storeys down.
They were taken to hospital to be treated for minor injuries and possible concussions. One resident was treated by Urgences Sante for smoke inhalation.
A few hours later at around 10:30 a.m., firefighters were called in to a commercial and residential building located at the corner of 5th Avenue and Wellington Street in Verdun.
A two-floor building where a third floor was being built was caught in flames. Around 25 firefighters quickly controlled the blaze. Robillard says investigators will determine the cause of the fire but have no reason to believe it is suspicious.
Robillard added cold weather conditions are making it harder for firefighters to work, which means they have double the amount of crew members tending to calls so they can rotate.
