No local body or foreign country “owns” Canada. Instead, King Charles III is the legal Head of State, with the Crown (represented by the Governor General), albeit acting as a figurehead in practice, while the Canadian government manages the country. Only about 11% of Canadian land is fee simple property (i.e., “privately” owned), while the remaining 89%, including all Indian Reserves, is “Crown Land.”
These facts actually strengthen my position that they apply, or should apply, equally to indigenous and non-indigenous peoples, including those living on Indian Reserves, tracts of Crown land administered by the government of Canada on behalf of both the King of Canada and its indigenous residents.
