If you want to go by the paleolithic timescale you don't even have rights to the British Isle. Old School Dominionists would have a fit over that one! 1982, I was a junior in high school ready to join military service when Canada, its people, its Provinces, and its Parliament voted to accept treaty and obligations to the highest laws of Canada Constitution. The Dominionists had ample time to argue anything they wanted to and they lost. Whatever history rewrite one may try to argue, it's to an argument they already lost a long time ago in 1982.
