I have a couple of things.
I've said this on a few occasions. NAFTA had the most stringent rules of origin for automobiles of any FTA in the world. In this agreement we have made them significantly more stringent. I think it's important to remember that on aluminum, for example, Canadian automakers are using North American aluminum. American automakers, by and large, are using North American aluminum. Admittedly, some Mexican automakers are using some non-originating aluminum, but their ability to do that is now going to be constrained. I think that's important. We've now got these very restrictive rules of origin.
I want to dig in a little to explain why the point about the higher regional value content thresholds is relevant here. For example, if it's a cast aluminum part or a stamped part, a significant portion of these parts is the metal content. If you're casting a part from non-originating aluminum, you will not wind up with an originating part. You won't be able to satisfy these 75% regional value content thresholds in the case of, say, an engine part, or 70% in the case of, say, a significant portion of the value of a radiator, which is an aluminum pour; you just won't meet that rule. As Steve mentioned, a 75% threshold is tough when certain electronics in a vehicle are, certainly in the near term, going to continue to be sourced offshore. Display screens are the best example of that.
I think this strengthening of the requirements across the board is pretty important. It means that for our aluminum sector, our steelmakers, our auto parts companies that have been very successful selling to Canadian and North American producers, there is an opportunity for them to do even more.
