I can't answer the status part, but I think I can speak to the international part.
Virtually every country that has emerged from whatever kind of government into a democracy--China, eastern Europe, African countries--has come to Canada; they are looking to us for our models and our leadership. So it's not that there are other examples so much as they see us as a model. Many countries have vast constitutional protections but no means to enforce them. They come here to talk to us.
