I got a similar call about a month ago from someone claiming to be from a Canadian Bank (I didn't hear which bank it was). He offered me a pre-approved credit card over the phone, he just needed to get my information (SIN, etc.). That's when I realised, who the hell would offer me a pre-approved card over the phone, and if they pre-approved it, don't they have my information already. I'm pretty good at spotting scams, but this one will catch a lot of people that are in need of credit cards.
