What you could have done with CUSMA is have an internal economic analysis of what you're negotiating priorities were. This could help to form your negotiating priorities. What do we want to get out this? Then, once you have your initial drafts, you would run the numbers again. At that point, you would use that information to determine if you wanted to make any further changes, or if you needed to. If you were to see that this was actually having an unexpected negative impact on the cultural industries in Quebec, for example, and it was a bigger driver than you had thought when you were negotiating, then you would put a bigger priority on making sure that you changed that language.
