Richard C.C. Peck says the decision not to press charges against four RCMP officers involved in the incident should be reexamined, Canwest News Service reported Wednesday.
Peck was appointed to look into the matter after a new report pointed to "factual material" not available at the time of the initial inquiry.
That material included expert video analysis of the tasering incident caught on a cellphone camera by a bystander at the Vancouver International Airport.
The victim, Robert Dziekanski, 40, spoke no English and had been wandering around the international terminal for 10 hours when he became distressed and began throwing furniture.
Mounties said he threatened them with a stapler but the camera footage refuted that charge.
Dziekanski died on the airport floor after being shocked five times.
