A young doe along the Gardiner made for a major traffic james on the Expressway and other routes on Monday afternoon.
The deer ran across live lanes before settling in a grassy area off the edge of the Expressway.
Toronto Police closed the westbound Gardiner near Parklawn at around 11:30 am for fear the deer would skip back out into traffic and trigger a crash. Cars backed up for three hours as staffers with Toronto Animal Services surrounded the doe, lying on her side in the grass.
The Gardiner was blocked in both directions near Parklawn for about 15 minutes just before 2 pm as veterinarians from the Toronto Zoo arrived on scene. The vets swept in, administered a tranquilizer dart, loaded the deer on a board into a waiting van and whisked the animal to the zoo.
The plan is to release the doe into the Rouge Valley once the tranquilizer wears off.
