Thank you.
Professor, I was very pleased to hear your comments on the analytical capacity or the lack thereof and the need for it in government. I think my colleague across the way would agree with me, based on his background as well as mine, that it's absolutely critical. It's emerging that the most critical component in the public safety, law enforcement, and anti-terrorism environment in which we live in our world is the analytical capacity to review and track individuals. I thank you for that. I think it's something that CBSA will work with government to increase.
You indicated that part of your concern was with the appropriate retention schedules. That's complex. There need to be some guidelines with regard to those, along with some flexibilities. I guess I'm left to wonder about this, given my background. When data is redacted, is gone, or we lose it to a retention schedule, it's amazing how many times we require that data and we no longer have it. I'm thinking of the recent example from Edmonton. If that data had been lost some way, how would we know and how could we track some of the concerns we have regarding public safety and terrorism, which is what Bill C-21 is supposed to do?
I know some balance needs to be struck and I know there are some groups that would have us be more concerned about retention and say we should destroy everything within years. You indicated that there are some streams, and that, depending on the purpose, we need to have different retention schedules. Can you explain that so it's a bit clearer and so we get it right?
