Retention is obviously an important issue, but I'll start by saying that it is legitimate for Canadian border officers and, for that matter, U.S. border officers to collect some personal information to determine whether the person who wants to be admitted should be admitted. Therefore, I'm not saying that no information should be collected. Some information is absolutely reasonable to make a decision about admission. But if we're within that area of certain pieces of information reasonably linked to the decision to admit, then our concern moves to how long this is retained—you're right to raise that question—and for what purpose it can then be disclosed to other departments.
