TORONTO – Investigators are trying to determine what caused a 4-alarm fire to burn out of control in Etobicoke Friday morning.
Firefighters were originally called to this scene near Birmingham and Islington Avenue around 2 a.m. for a truck fire.
But the flames quickly spread to a nearby industrial building.
The structure was engulfed in flames and crews on site were worried they will spread to nearby buildings.
Islington buses along this route were being diverted as a precaution.
No injuries have been reported.
