The Queen of England is not the Monarch in Canada, the Queen of Canada is. She does not act for England with regard to Canada. This is our problem whether the Queen is involved or not. Britain did not start the residential schools, Canada did.
It's wild how many people don't understand constitutional monarchy as a system of government.
