MONTREAL—Police suspect that a mentally unstable 35-year-old woman might be responsible for a fire in the Plateau-Mont-Royal apartment building that injured one person on Sunday morning.

The fire at 4550 de Brebeuf St. started at around 8:50 a.m. on Sunday. Firefighters were at the four-storey apartment building within minutes and had the blaze under control by 9:20 a.m.

According to Montreal police spokesman Danny Richer, the woman appears to have set the fire—she may face arson charges, although it’s too early to tell.

While evacuating the building, firefighters found a woman in a hallway who had serious burns on her hands and had suffered from smoke inhalation. She was transported to the Hotel-Dieu Hospital.

A two-alarm fire was reported in Pointe-aux-Trembles at 11:50 p.m. on Saturday night. While crews were at the fire within minutes, damages were estimated at over $100,000.

According to Andre Paquet of the Montreal fire department, the one-storey commercial building on Jean-Grou St. housed Systemes Paul Davis, a company that specializes in restaurant cleanups after fires.

A neighbouring dried fruits distributor reported that their product was damaged by the smoke.

The fire did not appear criminal.

A third fire broke out early Sunday morning when someone threw a Molotov cocktail at a gelato business in St-Leonard. Damage to the building was minor.
