Except, the US and Britain already made a treaty to make a simple border, which was largely done so because of settlements and population. That doesn't change here, because the only way to have enforced a claim to disputed territory would have been to have people there, which in itself would solidify their claim.Okay what if all the terroitories in the NW (Oregon, Washinton etc.) became part of Rupert's land? Historcally Canada bought Rupert's land in 1870 now if Britain which owned Rupert' land held until 1870 whn Canada bought it then the area is Canadian now.
And it still doesn't give Canada super-power resources and such. Instead, it gives Canada a richer "anchor" to the west to counterbalance the east coast.
