Human rights and First Nations people in Canada

I read here on Metis Bare Facts something that I remembered reading a small blurb about a few years back, about Canada having refused to sign the UN Declaration of Human rights of Indigenous Peoples. It really didn't make headlines though and I had forgotten about it until this morning. How can Canada criticize the Human Rights records of other countries if we can even recognize the rights of our First Nations?
