A 32-year-old woman has died and her two-year-old son remains in critical condition following a head-on crash in Hamilton Tuesday morning.

The crash occurred shortly after 7 a.m. on Highway 5, just east of Highway 8. Ontario Provincial Police say a westbound pickup truck collided with an eastbound minivan carrying three members of the same family.

The pickup was driven by a 20-year-old man from Millgrove, while a 35-year-old Cambridge man was behind the wheel of the minivan.

The 32-year-old woman was sitting in the front passenger seat of the minivan and was pronounced dead at the scene. Her young son, who was in the rear of the vehicle, was critically injured and taken to a local children’s hospital.

Both drivers were also transported to hospital with injuries that were not considered life-threatening.

OPP officers continue to investigate the circumstances surrounding the collision. Police say charges are pending as investigators work to determine what led to the crash.
