The eastbound lanes of the Gardiner Expressway were closed down for a number of hours on Wednesday night after an incident involving a woman.

Toronto Police believe they are looking for a vehicle that took off after hitting a person near Parkside Drive.

It happened just after 8 o'clock, but cops still haven't been able to say how the woman ended up on the Gardiner in the first place.

They did say the woman died at the scene.

Now, officers are asking for witnesses to come forward.
