My comment is very short.
The perceived time limit to deal with McIvor is only that: it's perceived. Canada successfully sought an extension. The comments from the court were that you could have received a longer one. I think Canada could have and should have made a significant commitment to consultation and said we're going to take 18 months to do this and let's see whether the court will agree. I'm betting, based on Supreme Court of Canada decisions, that they would have given you the time.
