How exactly you would do that is a very complicated question. A lot of effort went into looking at what happened to Maher Arar, for example, which was triggered by the sharing of information with the United States by Canadian law enforcement and national security agencies, and the consequences of that. We've had discussions about Canada not wanting to participate in or condone information-sharing practices related to torture, for example.
That is such a big picture and such an important question. It's actually outside the scope of SCISA, because a whole lot of information sharing that happens with the United States—and our other allies; it's not just the United States—happens outside the ambit of SCISA and any particular statute. Nothing in the Privacy Act, for example, limits the disclosure for those sorts of purposes, so that would merit a study entirely of its own within this committee.
At least where it touches on SCISA, I understand as part of the study you will be hearing from folks from the RCMP and CSIS and the Communications Security Establishment. I would ask them specifically what information has been shared within departments since they've had this ability under SCISA that they couldn't share before. What amount of that information has crossed the border? Once you have that information—and as parliamentarians you can require a witness to answer such a question—you're going to be in a much better position to understand what's going on. However, I don't expect you're going to get a straight answer.
