I would say that sometimes it's legitimate and sometimes it's not.
We have national security reasons for not letting certain investments into our country. We have a national security reason for not allowing certain products into our country or into our technological systems.
Then sometimes it's totally incorrect. The case in the U.S. a few years ago, I think, was an egregious case of not having a national security reason for preventing Canadian steel from going into the country. Agreements like CUSMA allow us to work through those disputes in a lot more productive way. Let's be thankful that we have these agreements to work through these things rather than doing them in thin air.
