Our worry is that if this deal doesn't get ratified, and particularly, if the President feels frustrated with Democrats, he may decide to withdraw from NAFTA. I still think there's a very real risk of that happening.
It then becomes an open question of what we return to. There's a legal debate under way about whether we would go back to the Canada-U.S. FTA or go to nothing at all. We know the U.S. business community is prepared to launch legal challenges in that event to try to delay it, but I would not downplay that risk. It's still a huge concern for business. Then we'd revert to WTO tariffs, and that would be disastrous for the Canadian economy, for companies that depend on access into the U.S.
That uncertainty continues to hang. That's why we want to see Canada ratify, Mexico ratify, to get this behind us and get into 2020 with, hopefully, no discussion of North American trade in the presidential elections.
