who call me

It's Canadian Tire MasterCard Security, calling to ask about some charges on your card, and verify if you made those purchases. Telus triggered them with 11x $10 successive prepaid withdrawals (which was already corrected by Telus) plus they asked about the purchase of a $3.08 app from Google. Verdict: Legit.

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

This number is legit. Had it happen twice in about two three years where someone copied my card and tried to make a purchase. Each time the attempted purchase was not by me. Card cancelled and a new one issued.  Wish I new where they copied my card!!!
