Well, what a difficult question. You're not talking to either an expert on borders or on public safety, a Canadian Border Service person who might be able to unpack it better than I can.
Can you unpack the security issues from the trade issues? Well—it's a bureaucrat's answer—yes and no. There are some things you can treat separately, and in the announcement last week the regulatory cooperation piece, which is directly related, is separated. There are, in the list of initiatives being taken with respect to the border, things that are separable, such as improving some of the infrastructure and some of the programs for trusted exports, or things like that.
Can you really fully separate these two issues in the modern world and in the context of security in the U.S., and for that matter, in Canada? It's a shared concern, security. No, I suppose ultimately you can't.
