Thank you very much, Madam Chair.
I want to thank all the witnesses for being here and for their commitment and experience on this file.
I'd like to dig down on a couple of things that have already been mentioned.
In terms of the buy America clause, it was pointed out by a company, and I believe it was IPEX, which came here when we had CUSMA witnesses, that one of the things Mr. Harper was able to do was get a buy America exemption.
I believe that Mexico, in the new CUSMA, had a buy America exemption. However, we failed to get a buy America exemption. We've been aware for some time that the Americans are not engaging at the WTO. By not using the leverage we had to get this exemption that we've had in the past, some people see this as a big opportunity lost.
I was wondering if you could comment, Colin. You've spent a lot of time in the U.S. Why is the United States not engaging in the WTO? What are their big issues that they want to have resolved?
