OPP Sgt. Kerry Schmidt said one vehicle contained five occupants and a male driver was the lone occupant of the second vehicle.

The impact of the collision caused both of the vehicles to roll over.

“One of the vehicles punched right through the guiderail, causing significant damage,” Schmidt said. “There were several other vehicles that were travelling westbound that were struck by debris and were damaged as a result of this collision.”

All six people in the two vehicles were taken to hospital for treatment.

Two of the victims sustained serious but non-life-threatening injuries and were transported to a trauma centre.

A crash closed the QEW in both directions in Mississauga Sunday morning.

Schmidt said the male driver of the second vehicle suffered minor injuries and is facing impaired-driving related charges.

Officers with the Port Credit OPP detachment are investigating the collision.

“It was raining at the time of the collision and we actively seeking any other witnesses that have information to help us,” Schmidt said.

The highway was completely shut down in both directions in the area early Sunday morning but police confirmed at around 8:30 a.m. that two right Fort Erie-bound lanes had reopened.

The highway completely reopened in both directions at around 5 p.m.
