A massive blaze has caused significant damage to an historic building in Regina's Warehouse District.

Fire crews were called Winnipeg Street and Eighth Avenue just before 10:00 on Tuesday night.

The building is the former General Motors plant, built in 1928 and taken over by the city in the 1960s.

It currently houses Regina Minor Hockey, Regina Education and Action on Child Hunger, the Grid Virtual Reality Arcade and other businesses and organizations. There were also a number of semis, bobcats, and other large machines housed in the building.

Fire officials haven't released any other details about the blaze, but loud bangs were heard outside the building as the fire burned.

Crews tell CTV News the fire was contained to the west side of the building. They are still on scene Wednesday morning putting out hot spots.

Traffic is restricted in the area. Drivers are encouraged to take other routes.

The cause of the fire and the extent of the damage are still unknown. No injuries have been reported.
