A fire broke out in a boarded-up home in the 200 block of Avenue K North in Saskatoon early Tuesday.
The Saskatoon Fire Department said it got a call around 4:30 a.m. Crews arrived to see heavy smoke coming from the home.
The fire was found in the basement, and extended throughout the building to the roof.
Utilities were shut down for safety reasons and the fire was extinguished from the exterior.
The fire department said the extreme cold created challenges for crews and equipment.
The fire investigator could not look for a cause for the flames due to the building being compromised.
Damage is estimated at $200,000 and an excavation company will be removing the building later Tuesday.
Fencing will be put up to keep people out of the area and the site will be filled and levelled.
Anyone with information about the fire is asked to call the Saskatoon Police Service at (306) 975-8300.
