The Ministry of Labour has been called in after a 37 year old man was severely injured on the job in Mississauga.
He was working on the roof of the Erin Mills Town Centre Monday night around 11 o'clock, when a roof truss collapsed, causing beams to fall onto the man.
He was trapped at first, but then freed by firefighters and taken by ambulance to a local hospital. From there, he was transported to a Toronto trauma centre (St. Mike's) by air ambulance, with serious chest injuries.
No one else was hurt in the accident.
Peel police say this happened in an area of the mall that is closed off to the public and there's no danger to the public right now.
The mall will be open on Tuesday, while the Ministry of Labour continues to investigate the accident, as well as how much damage it caused to the building.
