In a significant development that has prompted an investigation, the Special Investigations Unit (SIU) has invoked its mandate following a police-involved collision on Highway 400 in North York, Toronto. The incident occurred on the morning of Friday, November 28, 2025, at approximately 7:00 a.m.

According to reports from the Ontario Provincial Police (OPP), an officer from the Highway Safety Division was involved in a collision with a passenger vehicle in the northbound lanes of Highway 400, just north of Highway 401. This busy highway, a vital artery for commuters and transport across the Greater Toronto Area, was temporarily shut down for an on-scene investigation, leading to significant traffic delays during the morning rush hour.

The driver of the passenger vehicle was transported to a local hospital with serious, yet non-life-threatening injuries. Thankfully, the OPP officer involved sustained only minor injuries and was also taken to the hospital as a precautionary measure. Fortunately, no other injuries were reported in connection with this incident.

The SIU, an independent agency responsible for investigating incidents involving police that result in serious injury or death, is now tasked with determining the circumstances surrounding the collision. While the OPP expressed their commitment to cooperate with the investigation, they have indicated that further details will be limited while the SIU conducts its inquiry.

Highway 400 is known for its heavy traffic, especially during peak hours. The closure of the northbound lanes caused significant delays for drivers trying to navigate their morning routines. After a careful investigation at the scene, the highway has since reopened, allowing traffic to resume.

As this situation unfolds, it raises important questions about road safety and the protocol followed by law enforcement during high-stress situations. The OPP’s commitment to highway safety is paramount, and incidents like this underline the challenges faced by officers on the road.

For the affected driver and their family, the focus will undoubtedly be on recovery, while the SIU’s investigation will aim to provide clarity and accountability regarding the actions of the officers involved. As the community awaits more information, it serves as a reminder of the risks faced by both police and civilians on our roads.

In the meantime, drivers are encouraged to remain vigilant and adhere to traffic laws to ensure the safety of all road users. This incident serves as a critical moment for reflection on how we can all contribute to safer roadways in Ontario, especially as we head into the winter months when conditions can become hazardous.
