I don't see that it does. In fact, I think there's a concern here that I would have on a policy matter. There's about to be a very new Congress in Washington, and I don't think Canada wants to create precedents where it's saying that it's okay to make unilateral decisions. Be careful of what may come over the next couple of years in counter-unilateral decisions about border crossings.
