Canada also has the native nations.
On the edge of Calgary (1 million census) is the Tsuu t ina Nation. Calgary wants to complete a ring road, but it would have to go through Tsuu-t ina land. Negotiations are underway between the Province, the City, and the Tsuu tina to find a compromise that is satisfactory, but it may be several years before a settlement is reached.
This adds still another dimension to the meanings of 'nation.'
