Toronto police are looking for a driver after a late-night joyride landed a woman in hospital with life-threatening injuries.

Police believe the driver was heading north on Ontario Place Boulevard, near the Exhibition Grounds, and had stopped at a red light at Lakeshore Boulevard West.

The driver was waiting to turn left, Traffic Services Media Officer Clint Stibbe told 680 NEWS.

That’s when two women climbed on to the rear bumper of the car.

One of the women fell or jumped. The 22-year-old is now in hospital.

“The other woman remained on the vehicle for a short distance until she had the opportunity to get off,” Stibbe said.

Police are asking the driver to surrender to police.
