As Chris mentioned earlier, we haven't taken into account explicitly in our projection the issue of trade and uncertainty with NAFTA and the negotiations with the United States, because it's very hard to know exactly what is going to happen and how the negotiations are going to end finally. There is certainly a downside risk, if the negotiations don't go in our favour.
On the other hand, there are other things that we have not taken into account in that regard. The U.S. economy may actually perform much better than we are assuming in our projection, given that they are planning to significantly reduce their taxes and invest in infrastructure. Those things are on the two sides of this, and we haven't taken them into account.
Trade, though, is always an important issue for Canada, given that we are a small, open economy. While that uncertainty is important, we are expecting, as I said, that trade will contribute to growth over the next five years. This expectation is always subject to some risk and uncertainty, naturally.
