"Canada touted the ideals of these alliances far and wide, relishing the contrast with the United States, which stopped entering into treaties the same year Canada started"

That statement is a bit over the top. "Canada" entered into the treaties with the local tribes ( Nations ?!  .-) because the USA was on the verge of invading and anexing Canada - while pursuing Indians across our border. Thus the treaties served an ulterior motive of creating allies to help constrain the cavalry.

And I will now meander into a region where Angels fear to tread:
This whole issue of reconciliation and observing the treaties is such a political hot potato that debating how many Angels or warriors  can dance on this pin head is entirely futile - but eagerly supported by the Indian Act Industry lawyers at $400/Hr billing.

What "reconciliation" ? Most certainly won't happen given the current controversies. The treaties ? Past their "best before" .. 200 years old +/- .. and beyond their original context.
