It's possible that they would be impossible, but I don't know; I'm not a trade lawyer. I'm not going to suggest equivocally one way or the other. If you've looked at this yourselves, you'll know that there's a well-known Ottawa academic, Michael Geist, who has written that it looks as if it preserves cultural protection; there's a well-known cultural nationalist lawyer named Peter Grant who said that he thinks it's okay. So you have these differing views.
