Toronto firefighters say that a two-alarm fire broke out at an Etobicoke late Wednesday afternoon is now mostly under control.

Nine trucks and nearly three-dozen firefighters were involved in the response. They were called to the scene just before 5 p.m.

At about 6 p.m., firefighters reported some spot fires remaining.

There are reports that propane cylinders are involved in the fire. Efforts are being made to cool them down.

Firefighters say there may have been some explosions.

Witness Tanya Giglio, who works across the street from the warehouse, told CBC News via Twitter that she felt an explosion while inside her car.

The West Mall has been shut down between Dundas Street and Paxman Road as a result of the fire, police say.

The TTC says that its 112 West Mall route buses are diverting in both directions along The West Mall, Bloor Street West and The West Mall.
