In addition to what's already been said, I would think that it's important in this day of reconciliation that Canadians are.... They are becoming more understanding and educated about various indigenous peoples and nations, but there's still quite a ways to go to educate the public.
I would think that in a preamble there would be the notion of reflecting that indigenous peoples, being the original peoples of this land, have histories, cultures and their own nationhood and peoplehood, and there are distinctions, which I think also need to be kept in mind. Also, indigenous peoples' values are no different from anybody else's. We value what is ours and we want in many cases to rebuild what we've lost in this. I think that is something that is important.
Our cultural heritage has taken a massive assault. It takes the collective effort of all Canadians, I think, to assist in rebuilding that. Some messages along those lines I think would be helpful.
