First of all, dispute settlement mechanisms are critical components of trade agreements, because they give you that avenue when you have a disagreement. We have had challenges with the CUSMA. There's been a dispute with our American partners over what's called the super-core roll-up, which is a unique component of the rules of origin. Canada and Mexico won that case, but the U.S. did not comply with the ruling. We have had challenges.
We also had a side letter in CUSMA on section 232 tariffs that exempted Canadian production of up to 2.6 million vehicles from any future U.S. tariff actions, and that has not been adhered to. These are critically important parts of agreements, but of course all parties have to agree to implement them, and we've had some challenges recently, which has resulted in the current situation.
