Winnipeg firefighters are busy Wednesday morning battling a large fire in the city's North End. 

The fire broke out just after 8 p.m. on Tuesday in a single-storey, mixed-use structure on Jarvis Avenue near King Street. 

When crews arrived at the scene Tuesday night, large flames and plumes of smoke were pouring out of the building, with fire extending to a connected three-storey structure.

Due to dangerous conditions, crews were unable to enter the buildings. They used three aerial ladder trucks to apply water to the fire and protect two additional adjoining structures. 

Crews remain on scene and are expected to throughout the day. As a result, Jarvis Avenue is closed between Main and Schultz Streets, and Derby Street is closed between Dufferin and Sutherland Avenues.  

The cooler weather has also created challenges for firefighters. Crews have had to rotate in and out to provide them with breaks from the cold. 

At this point, no injuries have been reported.

The Winnipeg Fire Paramedic Services says both buildings have sustained significant smoke, water and fire damage and are considered a complete loss. Emergency demolition is being arranged as the structural integrity of the buildings is compromised.

The cause of the fire remains under investigation.
