A 29-year-old woman was backing out of a parking spot, near Walkley and Albion roads, at about 9:15 a.m. ET Monday when the strong wind caused the door to open suddenly and violently, said J.P. Trottier, a spokesman for the paramedics.
The woman tried to close the door, but the wind pulled it back and she partially fell out of the car.
Her leg was caught under the front wheel as the car continued to reverse, running over her leg.
She was taken to hospital in serious condition with a crushing injury, paramedics said.
No other information was immediately available.
