Lambton OPP say two people died in the massive pileup on the 402.
Dozens of cars and transport trucks collided on the westbound 402 near Oil Heritage Road around 8:30am yesterday in sudden snow squalls which created whiteout conditions.
The highway just reopened around 9 this morning as the OPP’s technical traffic collision investigators tried to determine exactly what happened..
At least 30 people have been treated for injuries and people involved in the crash were taken to warming centers in Wyoming.
Police have not yet released the names of the people killed in the accident.
