A deadly crash that occurred on the QEW this morning remains under investigation by police.

The Ontario Provincial Police say that on Sunday morning, a Nissan Murano had stalled in the right lane of the eastbound QEW near Cawthra Road in Mississauga.

A tow truck subsequently parked in front of it and a Ministry of Transportation crash truck behind it, to warn others of the hazard.

Shortly before 7:30 a.m., police say that a van subsequently struck the crash truck, as well as a Mazda, before coming to rest on the left shoulder.

That Mazda then ended up striking the Nissan, which was pushed into the tow truck.

Police say the two people inside the van were ejected. One of those occupants, a 30-year-old Mississauga man, died at the scene. The driver of that van suffered life-threatening injuries and was taken to hospital.

The three people inside the Mazda were taken to hospital with minor injuries, as was the driver of the Nissan. The MTO crash truck driver also suffered minor injuries.

The crash and subsequent investigation kept the eastbound lanes of the highway closed at Dixie Road for the rest of the morning and much of the afternoon. It has since reopened.
