Acting Platoon Chief Martin Mills says the building is a semi-detached home that had been turned into a number of apartments.

Mills says they’ve determined the cause was careless smoking and damage is estimated between $50,000 and $60,000.

He says a woman who uses an oxygen tank was taken to hospital with non-life threatening injuries.

All the other residents were able to make it out of the building safely.
