A male driver is dead after crossing a median and striking a parked Toronto police vehicle at Lake Shore Boulevard and Colborne Lodge Drive, officers say.

Const. Clint Stibbe said a commercial inspection vehicle was parked in the area when the driver of a Honda Civic lost control and struck the police vehicle head-on.

The driver of the Civic was pronounced dead at the scene.

“We are investigating the possibility that a medical episode preceded the collision,” Stibbe said.

A passenger in the Civic was not injured. Occupants of the police vehicle were not injured.

Roads in the area remain closed for an investigation.
