Damage from an early morning fire on Cataraqui Street at Pierre Avenue has been set at $150,000.
Crews were called to the vacant duplex at about 1:30 this morning to find heavy smoke and flames on the first floor.
The flames spread through the 2-storey building, eventually breaking through the roof forcing crews out of the building.
Investigators were not able to find the cause of the fire because of the extensive damage to the building.
There were no injuries from the fire.
