A two-storey house in Saskatoon was on fire early Tuesday morning, and the Saskatoon Fire Department said three fire engines, a ladder truck, a rescue unit and the battalion chief responded to the blaze.
Fire was visible from the back of the building in the 900 block of Avenue J South, and the detached garage caught flame as well.
Both buildings were vacant, and the fire was under control by 3:59 a.m.
Investigators said the cause of the fire is suspicious, and damages are estimated at $150,000.
The investigation is now being done by the Saskatoon Police Service.
