Abstract (Document Summary)
"I went to a Green Machine instant teller in Welland on Sunday to pull out $5 for gas," said [John Bordynuik], 20, a student of nuclear physics and computer technology at Brock University in St. Catharines.
Curious to know just how much the Green Machine thought he had, Bordynuik began punching buttons to transfer $95,000 at a time from his chequing account to his savings account.
That's somewhat different from this account of the story -
Years later he would get his 15 minutes of fame. In 1989, he told his bank he found $1.2 million in his account that he didn't remember depositing. Bank officials in Toronto insisted there was no mistake and the money belonged to him, while staff at the local branch scrambled to reconcile more than a million missing dollars. Bordynuik stuck with his story, which soon made headlines across Canada. Papers proclaiming "Honest John Returns $1.2 million" caught the eyes of influential Ontario Legislature IT staff.
