Again, I wouldn't be privy to any of the detailed classified information on those pathways. We might look to the fact that we have a western border as well. I'm not sure how much organized crime is passing, but certainly issues relating to gun smuggling, for example, and theoretically to drugs, would warrant looking to that western border.
I think, more generally, a lot of the pathways are through southern Canada, reaching up to the north. In essence, investing in broader, more robust safeguards for our southern borders is ultimately helping us to address some of these northern aspects of our threat environment.
