On Friday, November 28, 2025, at approximately 7:00 am, an Ontario Provincial Police (OPP) Highway Safety Division officer from the Toronto Detachment was involved in a collision with a passenger vehicle in the northbound lanes of Highway 400, north of Highway 401.

The driver of the passenger vehicle was transported to hospital with serious but non-life-threatening injuries. The officer sustained minor injuries and was transported to hospital as a precaution. No other injuries were reported.

Highway 400 northbound was temporarily closed from Highway 401 and Black Creek Drive to allow for the on-scene investigation but has since reopened.
