I would counter or add that optionality was a key part of the last agreement. It worked well for all regions, and the lack of details around a quota-only approach has resulted in either uncertainty or disagreement clear across the country. It affects regions in the east that were exempt. It affects Quebec, which has a separate view in terms of what should happen. Ontario, which had quota, is unsure in terms of what that means, and in the west, there is a preference to have a structure that allows them to be most competitive in the world market.
