its legit. called me about a TV I ordered minutes ago from Costco Online.they are on the ball.

The message left from this number was Canadian Tire Fraud & Security Department

Called me to report that my wife's card had been used in the Carribean (she was there indeed). Just to show those guys at Canadian Tire are on the ball!!

Got an alleged call from Candian tire Mastercard security. not sure about this

Yeah,Got a call from this number. Returned it, and it seemed legit. Although the woman on the other end did ask for my Credit Card number, security code and date of birth: all the information she would need to gain access to my account herself. Not sure about these guys. Have only had the card with them for 2 months and already I supposedly have an issue?Hmm...
