It happens fairly frequently.
Where there is ambiguity, where there is any kind of vagueness, banks—and I think credit unions would act the same way—err on the side of caution. You're conservative and you're more reluctant to complete transactions.
That's not necessarily our bank, but we've seen it with other international financial institutions, particularly those that have been subject to enforcement from other regulatory regimes. They will just block it, and they will not deal with certain countries at all. They don't even acknowledge that certain exceptions are permitted. They don't even want to look at that, because of the cost of compliance and the need to have the staffing to look at it and, indeed, because of the potential risk.
We take a position. We try to look at every transaction on a case-by-case basis. What a lot of Canadians don't realize is that although we may clear it as a Canadian bank, there's another party in another country that has to also be a participant in this transaction. They take a policy approach and they say they won't do it. That has had detrimental impacts on our customers. We try to explain to them that it's not us, that it's the other clearing bank that won't do the transaction.
