One person is dead and four others are injured after a two-vehicle collision on the westbound lane of Highway 407 in Whitby, said OPP, Friday night.

OPP Sgt. Kerry Schmidt said one of the vehicles was driving eastbound west of Lakeridge Rd. when it crossed the median and was struck by an oncoming car from the westbound lane. Police were called to the scene around 8:15 p.m.

A 25-year-old man, who was in the rear passenger seat of the car that crossed the median, was pronounced dead at the scene, Schmidt said.

He says the driver and another passenger in that vehicle have non-life threatening injuries.

The driver and passenger in the other vehicle were both taken to hospital with critical injuries
