Police say the 52-year-old woman was found trapped under the car in the south lane of East 13th Avenue near Commercial Drive on Friday afternoon by her neighbours who spotted the car in the middle of the lane with two dogs inside.
Police, firefighters and ambulance crews responded to the 911 call, but the woman was pronounced dead at the scene.
Const. Brian Montague said it is not clear if the woman was unloading or loading the car, but it appears it slipped out of gear.
"The car was not running, the keys were not in the ignition, but it's a standard transmission vehicle. For some reason, or somehow, the vehicle came out of gear and rolled backward over top of her."
