Do you mean a WTO challenge saying that the product has to be made here in Canada? I mean maybe.... I don't know.
By the way, I am probably one of the only people who has gone to the WTO in Geneva and spent time there. I was the first CEO who went there, for two weeks. I lobbied and beat China at the WTO on continuous circular welded pipe that came into the U.S. We beat them in 2008. The imports from China went from 800,000 tonnes a year virtually down to zero, but guess where they went? They went to Thailand, to Vietnam, to Oman, and the UAE. They went everywhere else. That's where China shipped their steel to circumvent the duties. That's how this game works.
When you talk about the WTO, nobody plays by the rules, and the Chinese are the worst offenders. I don't even know why they're in the WTO. They have broken every accession protocol. It's a joke.
