Two people are dead after a three-vehicle collision Sunday evening in Mississauga on Hwy. 401, police said.

Eastbound lanes of Hwy. 401, which were closed Monday morning, have opened after crews cleaned up the scene.

All express lanes are open at Hurontario. Drivers can access most collectors lanes at Hwy. 410 and Hwy. 403 ramps, except the left collectors lane, OPP spokesperson Sgt. Kerry Schmidt said Monday afternoon.

The collision occurred around 9:30 p.m. and involved three vehicles, including a transport truck, on Hwy. 401 near Dixie Rd.

Initial reports indicated the driver of a red Corvette eastbound on the 401 was making an aggressive lane change prior to clipping the transport truck, Schmidt said.

When the vehicles collided, the transport truck went over the concrete wall, rolled over in the express lanes and caught on fire, he said. He added there was “massive” damage to the median between the express and collectors lanes.

A third vehicle, a silver Mazda, suffered “extensive” damage, he said.

Schmidt said the two occupants of the Corvette were taken to hospital, where the 34-year-old driver was pronounced dead. One of the two occupants in the other damaged vehicle, a 77-year-old woman, also died in hospital.

Three people who were taken to hospital as a result of the collision have since been treated and released, Schmidt said.

As a result of the collision, some people drove the wrong way on the highway or on greenspaces to try to get around it, Peel police tweeted Sunday night.

Schmidt said police are looking to speak to witnesses or people who might have dashcam footage of the crash. He asked anyone with information to contact Port Credit OPP at 905-278-6131.

“Obviously we want to provide answers to the families who are now grieving the loss of loved ones, and try to prevent this kind of sad situation from happening anytime again,” he said.

Elsewhere in the GTA, northbound lanes of Hwy. 400 at Major Mackenzie in Vaughan were closed Monday morning due to a police investigation. They have since re-opened.

York Region police say they found an injured man on the highway after 5 a.m. Monday morning. He is in hospital in serious condition, police said. It is unknown how he sustained his injuries.
