Police say a suspect who robbed a Mississauga bank at gunpoint is also wanted for at least 18 bank robberies across Canada.

Peel Regional Police said the man entered the TD Bank at 1540 Dundas St. E., near Dixie Road, at approximately 7:30 a.m.

The man was carrying a gun and a black bag, and wearing a mask, hard hat and construction vest.

Police say he demanded money, then fled the scene with an unknown amount of cash.

Following an investigation, police said the suspect is believed to be the same man wanted in several other cases.

Last June, the Canadian Bankers Association announced a $50,000 reward for information leading to the arrest of the man dubbed the "vaulter bandit." The robber received his nickname after a string of robberies in York Region in 2010, where he vaulted over bank counters with a handgun.

After targeting York Region, the bandit went on to rob banks in Mississauga and Hamilton in the same style. He was identified in 2011 as a suspect in four bank robberies in Calgary. He then returned to Ontario, robbing an Ottawa bank in May 2011, before heading back to York Region, police said.

Prior to the Friday heist, his most recent robbery was a TD Bank on Clock Tower Road in Toronto last May.

Investigators are searching for a suspect described as white, between the ages of 45 and 50 with grey hair. He is approximately 5-foot-10 with a medium build, and was wearing jeans with the vest and hard hat during the Friday robbery.

Police said he may be travelling in a silver four-door Chevrolet Cruze.

In a message posted to Twitter on Friday, Peel police warned witnesses not to approach the suspect.

Anyone with more information is asked to contact police immediately.
