I think it is unique, at least in the context of Treaty No. 9. I think as we look more closely, we learn more about the post-Dominion Lands Act treaties that went into place across the Prairies, and we find all kinds of instances in which bands of Indians—which is a very loose definition, involving an artificial construct nine times out of 10—had forced amalgamations. The loss of identity and the loss of the independence to govern one's own band happened all over the place. So it is prospectively not that unique.
