The former Nygard warehouse on Notre Dame Avenue suffered significant damage after a fire Tuesday morning.
The city says crews were called to the scene at 5:53 a.m. and found heavy smoke and flames coming from the building.
Crews fought the fire defensively all morning with the assistance of two aerial ladders and landlines, while the WFPS drone provided situational awareness. The fire was declared under control in the early afternoon.
Parts of the building collapsed and were brought down by heavy equipment. Crews were still on scene Tuesday night to address any flare-ups.
Platoon chief Don Enns told Global News that a roofing company was doing repairs and propane tanks on the roof collapsed into the warehouse.
No one was hurt and the building was empty at the time.
The building has been closed for a few years after the company dissolved in late 2019. The former owner, Peter Nygard, faces charges of sex trafficking in the United States.
