Matt Mackinnon hailed a cab with a friend at the corner of St-Laurent and Sherbrooke Saturday night.
The car looked real and the driver told them he worked for Diamond Taxi.
"As soon as we got in the cab he was very chatty, he was taking our minds off of anything that might distract us" Mackinnon told CTV Montreal. "He was asking us where we were from, what we do, all that kind of stuff."
The driver insisted the fare be paid using a debit card.
On the way to the Palais des congrès he told Mackinnon that the charge on his debit machine was running low.
"One of his coworkers was in the area and he had a charger for it," Mackinnon said. "The guy popped his head in and plugged what just looked like a simple plug to the debit machine."
Mackinnon was given a receipt and left the taxi.
Before he realized that the bank card the driver gave him back was not his, Mackinnon's card had been used at two ATM's to withdraw hundreds of dollars.
Dominique Roy, the president of Diamond Taxi said while the receipt looks real, it's not.
"It's very easy to get this kind of receipt. So my guess is someone uses our receipt to make fraud," he said.
Roy said all transactions and taxis are tracked, and the company has no record of any of its drivers picking someone up at that corner at that time.
Roy suggested that anyone looking to take a taxi call ahead or book one online, because it's easier to track official requests.
He also said if a driver insists on being paid by debit it should raise a red flag.
"That's not normal. Usually drivers insist on getting cash, not debit or credit card, they hate that. They do it, they accept it because it's mandatory but they don't like it."
Montreal police said they are investigating.
