A CIBC cash machine started dispensing Canadian Tire money at a mall outside of Moncton, N.B.

Kayla Peters, 16, said she was shocked when she withdrew $60 on Nov. 29. She received two $20 bills and two $2 bills in Canadian Tire money.

"I just stood there for a second wondering what I should do, but then I heard some other people talking about it and it turned out I wasn't the only one."

The ATM spat out Canadian Tire bills ranging from 10 cents to $2.

Canadian Imperial Bank of Commerce officials say four people have been reimbursed for the mistake.

"It clearly must have come in from maybe some of our business customers who package up their own cash," said Rob McLeod, spokesperson for the bank. "We're still tracking down exactly what the source was."

McLeod says CIBC has confiscated the fake money as part of its investigation.

The ATM spat out 11 Canadian Tire bills in denominations ranging from 10 cents to $2.

"It appears to be a very isolated incident," said McLeod.

It's the second recent embarrassment to involve CIBC. Last week, a junkyard owner in West Virginia revealed he was suing CIBC because it failed to stop faxing him private financial information about its clients.

The bank said it knew about the problem and thought it had been fixed in 2002. CIBC has ordered its employees to stop using the bank's internal fax system to send customer information between offices.
