The United States has a law, which they haven't used very frequently, that allows their customs to seize goods at the border that are possibly made with forced or slave labour. The European Union is also very concerned about human rights and links it with market access. Canadian companies that aren't doing anything about this risk that market access.
If the United States starts to enforce this law more—several of my partners are ex-federal prosecutors in the U.S. who feel that this is going to happen—those laws can be weaponized as part of a trade dispute. A fantastic way to deny Canadian companies access to that market is to say, “We're not going to allow you to provide those goods into the United States unless we have some sort of guarantee that you don't have a bloody supply chain.”
There are all kinds of risks out there. It would take a small tweak of American law to do that. In the American system, as I put in my paper, there is systemic pressure already, despite the current regulatory regime. I think we'll regret it if we don't deal with it now.
