I think it would be quite dramatic, actually. The global economic and financial system, and ours in particular, has evolved to be one in which we are integrated with each other. In Canada's case, we are particularly integrated with the United States.
If we end up in a world in which the United States alters the rules of the game and decides to put up walls and put up borders, whether they're physical, regulatory, or legal, I think you are fundamentally altering the economic landscape. That, I think, would have very significant economic impacts for a very long period of time. It could be that after 10, 20, 30, or 40 years we will have adapted to a world in which that works very well. It's pretty hard to see that in the near term it would be anything other than fairly traumatic.
