I though NAFTA was supposed to tear down trade barriers like this

It was supposed to, but the U.S. decided to apply tarrifs and ignore the WTO and NAFTA rulings on the matter. What's the point of NAFTA if the U.S. isn't going to play by the rules?

"What's the point of NAFTA if the U.S. isn't going to play by the rules?"

The ruling in this case was in favor of the US. Canada doesn't like it and doesn't want to play by it.
