But after the RCMP and the U.S. Secret Service raided Bourassa’s home, he still had a card to play because authorities did not know where the remainder of his special paper and fake twenties was hidden.
“And that made them crazy, so Secret Service was here all the time, following me around all the time,” he told "20/20".
In March, he agreed to turn over the remaining fakes and paper in return for the deal his lawyer worked out with Canadian prosecutors.
U.S. Secret Service Deputy Special Agent in Charge Stuart Tryon declined to comment on Bourassa’s short prison visit, beyond saying the case was "handled by the Canadian government per their normal procedures." Tryon confirmed that Bourassa is not wanted in the U.S.
Canadian authorities said their investigation into the counterfeit ring is continuing. They believe Bourassa is going public now to claim credit in order to protect the leaders of the organized crime group with which he is associated.
“Evidence suggests there’s more stashes of paper, more stashes of counterfeit notes out there and there’s more people involved,” said RCMP investigator Adams.
“It takes a network of people to pass all these bills, it’s a huge quantity so you can‘t just trust a couple of people,” said RCMP investigator Michaud. “You need a big network.”
Bourassa insists it was all his operation but would not say whether there is still more counterfeit money hidden away or how much he profited from his operation.
Tryon of the Secret Service said that the American public should "rest assured that only one hundredth of one percent of currency that is in circulation is even perceived to be counterfeit."
“That number is so small because we do a great job in investigating these cases, as [do] our law enforcement partners,” he said.
The Secret Service says there were more than 3,500 arrests by American law enforcement last year of people attempting to counterfeit U.S. currency. The $20 bill was the most widely passed of the fake notes.
But what Bourassa and the Mounted police investigators agree on is that there are lots of his fake $20 notes still in circulation in the U.S., virtually undetectable.
