When I started, people weren't even being fingerprinted. More recently people are fingerprinted, and the use of fingerprints has proven to be an effective way of detecting fraud and being able to identify people, so obviously, using biometrics appropriately and in a fashion that respects privacy is not a bad idea.
That said, it would be vitally important, if we're going to start talking about using biometrics, to ensure two things.
One is accountability mechanisms, because without accountability, when you're now further increasing the power of CBSA, it would be extremely dangerous. You would have to also be very careful about how we did it so as to protect privacy concerns, and that would require a detailed and careful consultation with the Privacy Commissioner.
However, it's not a bad idea.
