You're not familiar. It is the case.
Is there any advantage for banks to cooperate? For instance, Canadian banks that have holdings in other countries.... I believe in the carrot and stick analogy: you either use a carrot to get somebody to go in one particular way or you use a stick. Those are the only two methods that I've ever seen to be effective.
In this particular case, is there any carrot available for Canadian banks that actually cooperate, not only with regard to tax cheaters but to people who want to be tax cheaters? For instance, people come forward to bank managers and say, “Listen, I need to find a way to hide these funds or to transfer these funds out of Canada into your bank so that I can avoid those taxes.”
