Well, that's where I said that without maybe some study, I couldn't give you a useful answer. Part of the difficulty in giving you a useful answer is because of what a privacy commissioner, who has basically the same status as a member of the public vis-à-vis foreign governments, doesn't know.
In terms of mechanisms, I know that my colleague, the U.K. commissioner, Richard Thomas, has been very active on this. I would call attention to the U.K., but the U.K. may not have the same security challenges as Canada. That is not information I'm privy to.
