Major Highway Reopens After Morning Collision
A serious collision involving an Ontario Provincial Police cruiser and a passenger vehicle forced the closure of northbound Highway 400 at Highway 401 during Thursday morning's rush hour. The incident occurred at approximately 7:00 AM on November 28, 2025 in the northbound lanes near Finch Avenue.
Emergency Response and Injuries
Both the police officer operating the cruiser and the driver of the other vehicle required medical attention following the impact. Emergency medical services transported both individuals to hospital for treatment. The extent of their injuries has not been publicly disclosed, but their conditions were serious enough to warrant hospitalization.
The Special Investigations Unit has invoked its mandate and taken charge of the case. The SIU automatically investigates incidents involving police that result in serious injury, death, or allegations of sexual assault.
Traffic Impacts and Cleanup
The collision caused significant disruption to morning commuters traveling through the busy highway interchange. Northbound lanes remained closed for several hours as police investigated the scene and cleanup crews worked to clear the wreckage.
The highway fully reopened to traffic later in the day, with officials confirming all northbound lanes were accessible by the afternoon. Commuters experienced considerable delays during the closure, with many seeking alternative routes through Toronto's already congested roadway network.
Police are urging any witnesses to the collision or anyone with dashcam footage to contact the SIU as their investigation continues. The circumstances leading to the crash remain under active investigation by the specialized unit.
