I can't answer the entire question.
Canada was the first major industrialized country to ratify the Convention on Biological Diversity, in 1992, and SARA flows directly from that. There were island states—the Marshall Islands—and Monaco, very small countries, and then we ratified in 1992, so we took a lead at that time, for whatever reason.
Ours is a very new law. We think there are on the order of 36 such federal statutes around the world now. We have not done a full evaluation of which ones work better or are better or what the differences are. The listing process we have, whereby we have an independent scientific committee that assesses, and then a government decision on whether to list, is better than that of some other jurisdictions because of that clarity or that separation.
After that, I don't know where we stand. I don't know whether anyone else here has a comment.
