Generally speaking there are no direct impacts on private land ownership, in that land claims are settled through three main tools. The first is the provision of crown land, either federal or provincial, if it's available; the second is the provision of cash in substitution for providing land; and the third is that the cash enables the given indigenous nation to purchase land on a willing buyer/willing seller basis.
There's no direct impact, in that we don't expropriate or the government doesn't buy up land from third-party private individuals in order to then make it available.
