One of the things we found is that it isn't always consistent. I couldn't provide you with a list of countries that don't allow access to dual citizens. That's one of the situations we see. In some places, we'll get access to a dual citizen in one case, and then depending perhaps on the local authorities, not get access in another case. That's something we can point out to these countries as well, that we've had access to one Canadian citizen but not to another.
