Police have dubbed him the Tunnel Rat Bandit since most of the robberies — six of the eight — have happened on the subway line, and each time, the suspect fled into the subway after the robbery.
Police released video of the man, who conceals his face with hats and scarves and sometimes a fake beard, both in the banks he allegedly robbed and in one instance a video of him entering the subway.
Watch that footage here.
The bank robberies occurred between January 6 to March 11. He described by police as white, slim build, 5'9" to 6'0, and in his 30s.
Malcolm Chilvers of the Canada Bankers Association said the banking industry is interested in seeing the unknown suspect brought to police. The Bankers Association is putting up the $10,000 reward for information that will allow for the arrest and conviction of the crimes.
"Bank robbery is taken very serious in the industry," he said. "It's definitely a personal crime, from our perspective. The people most impacted by these robberies are the bank employees and customers."
