The WTO bound rates for tariffs really aren't that high, so you'll hear about the impact being very minimal. I heard it out of Global Affairs when NAFTA was first being renegotiated, to not worry, that it's a small amount, 1.5% on average or something like that.
That's not the problem. The problem is all the trade rules that come with NAFTA. Take, for example, the business visa that you talked about earlier. If that goes away, we're in very deep trouble.
It's not just the bound rates and the tariffs; it's all the other uncertainty, the rules we trade by. That's what matters.
