More than 100 firefighters battling major fire in Etobicoke

Over 100 firefighters are on scene at a massive, five-alarm fire in Etobicoke.

Over 100 firefighters are on scene at a massive, five-alarm fire at an industrial building in Etobicoke.

According to Toronto Fire, crews were called to 35 Vulcan Street, near the intersection of Martin Grove and Belfield roads, at approximately 1:15 a.m. on Friday.

First responders say the fire initially broke out in adjacent tractor trailers before the building itself caught fire. It is alleged that the fire was caused by an initial explosion, but it is not yet clear what exploded.

Toronto Fire is largely concerned with containing the fire due to a high number of combustibles on site, including "thousands of litres of lubricants" and a neighbouring lumberyard.

This incident is being treated as a "full hazardous materials response," according to Toronto Fire.

The Ministry of Environment has been notified about this incident. No injuries have been reported, but Toronto Fire continues to describe the blaze as "out of control."

Martin Grove Road is closed south of Vulcan Street. Local residents and businesses have been advised to keep windows closed and shelter in place if possible.
