I guess what we're really talking about is accuracy. There are general provisions right now in the Privacy Act for all government departments that any information they're collecting, using, or disclosing should be reasonably accurate and that they should take steps to ensure that it is.
Our particular concern stems from the tragic case of Maher Arar. From information that turned out to be inaccurate and that may not have been adequately vetted before being handed off to foreign governments, we wound up with a Canadian citizen being detained and tortured, with all kinds of horrible things. That's really the worst-case scenario, and it's a great reason for being really careful with the information we're sharing, particularly when it is being shared with a foreign power.
