Using their list or at least following a similar process could make a lot of sense. During the USMCA negotiations, an area of real dispute between Canada and the U.S. was the transshipment of Chinese steel. The United States had concerns that steel bound for the United States was coming in through Canada.
We can't afford to have Canadian exports to the United States cut off because of American concerns. For instance, there could be goods produced from forced labour transiting through Canada. We should not be allowing that alone to happen, because it's bad, but separately it's also bad for Canadian interests directly.
