A 50-year-old woman is dead after a car collided with a TTC bus in Scarborough Thursday night.

Just after 6 p.m., police say a westbound 2002 Honda Accord on Sheppard Ave. E. and Water Tower Gate, east of Morningside Ave., struck a TTC bus from the rear while it was a servicing at a bus stop.

Paramedics say woman was pronounced dead at the scene.

The 47-year-old male driver of the bus was not injured, but a TTC spokesperson said a passenger on the bus was treated at the scene for minor wounds.

Toronto police traffic services Const. Clinton Stibbe said it is too early to say what caused the collision.

The transit agency says it is co-operating with police during their investigation.

Police closed all lanes on Sheppard Ave. E. from Water Tower Gate to Conlins Rd. for the investigation, but they have since reopened.

Police is asking anyone with information on the collision to contact investigators at 416-808-1900 or Crime Stoppers anonymously at 416-222-TIPS (8477).
