The passenger, a 48-year-old woman with cerebral palsy, was forced out of the vehicle on a residential street a short time later.
The woman was assessed by EMS and determined to be OK.
Police are still trying to locate the carjacker, who is described as in her 30s, with a heavy build with long brown hair in a ponytail, wearing a grey hoodie, grey winter jacket with fur-lined hood, black pants and brown shoes.
The vehicle is a blue 2007 Toyota RAV4 with Alberta license plate ZSK727.
