Ontario's police watchdog is investigating a collision in Vaughan that injured a York police officer and two civilians.

The Special Investigations Unit (SIU) invoked their mandate on Thursday after a vehicle struck a police cruiser that was pulled over on the shoulder of Highway 407 just west of Jane Street.

Emergency crews say a York Regional Police vehicle was in the westbound lanes of the highway around noon on Thursday when an officer pulled over a vehicle.

The driver of the vehicle that was pulled over was asked to sit in the back seat of the vehicle, according to a news release from the SIU.

Shortly after, the cruiser was rear-ended by another vehicle.

York Regional Police say all three people were taken to hospital following the collision.

The officer suffered minor injuries, while the condition of the other two people was not immediately available. 

The westbound lanes of Highway 407 at Jane Street were closed to traffic for several hours after the crash but have since reopened.
