Service on GO Transit's Milton line has resumed after a massive fire at a commerical property in Mississauga forced trains to stop running on Wednesday.

Aerial video footage of the scene showed heavy black smoke rising from a building in the area of Dixie Road and Dundas Avenue West.

No injuries have been reported, but Mississauga Fire has warned residents to stay away from the area.

Anne Marie Aikins, a spokesperson for Metrolinx, said yesterday on social media that crews needed to access the GO transit corridor to battle the fire. Trains were holding at Dixie GO Station and several trains along the Milton line were cancelled.

In a tweet on Thursday morning, GO Transit said trains on the Milton line would resume this morning but there would be two fewer coaches.

Police have not said what caused the fire. Roads in the area were closed as crews work to put out the fire.
