I would think that if any measure of that sort were ever to be contemplated sometime in the future, any request or proposal that came forward from Canada would include with it the measures to ensure that there was proper and full supervision by Canada with respect to any activity by other NAFO parties within the Canadian zone, be it for scientific research purposes, enforcement, surveillance, or whatever to ensure that Canadian sovereignty was in no way being compromised.
