Officials say a fire in a southwest Calgary townhouse on Sunday night likely began in the kitchen. The Calgary Fire Department was called to the scene in the 4500 block of Richardson Road S.W. at about 8:30 p.m. When they arrived, crews found smoke pouring out of the front door and a large fire in the kitchen. The blaze was quickly extinguished without further incident. The occupants of the home, who had escaped on their own before firefighters arrived, were assessed at the scene for smoke inhalation but were otherwise uninjured. The fire was limited to the single unit of the complex, which will not be habitable for some time.
