One man is dead and another is seriously injured after a multi-vehicle crash shut down part of the eastbound QEW in Mississauga on Sunday morning.

The deceased, a 30-year-old Mississauga man, was a passenger in a van that collided with a Ministry of Transportation truck, then spun out and collided with other vehicles at the scene, police said. The 30-year-old was apparently thrown from the vehicle during the collision, police said.

The driver of the van, a 25-year-old man from Beeton, was also thrown from the vehicle and is in hospital with serious injuries, according to police.

Five others were treated in hospital for minor injuries, police said.

The MTO vehicle was one of two on the highway to protect a disabled vehicle in the right lane, police said. FIve vehicles were involved in the crash, including a tow truck.

A witness at the scene told CP24 that she saw the van weaving through traffic before the collision.

All eastbound QEW lanes between Dixie Road and Cawthra Road were closed for several hours as crews worked to clean up the wreckage.
