Ontario brought a motion to adjourn the Stage Three trial of a complex treaty rights claim sine die, pending the Supreme Court of Canada's decision on the appeal of Stage One and Stage Two.

The plaintiffs, interveners, and Canada opposed the motion.

The court applied the test for an adjournment, balancing the interests of the parties and the administration of justice.

The court found that the risk of proceeding was manageable, while the prejudice to the plaintiffs and the administration of justice caused by further delay would be significant.

The motion to adjourn was dismissed.

The Crown appealed the Stage One and Stage Two decisions regarding the interpretation of the Robinson-Huron and Robinson-Superior Treaties of 1850.

The trial judge found that the Treaties' augmentation clause imposed a mandatory obligation on the Crown to increase the perpetual annuities if the economic circumstances of the ceded territories warranted it, without a hard cap of $4 per person.

The Court of Appeal unanimously upheld the trial judge's conclusion that the Crown has an obligation under the honour of the Crown to diligently implement the augmentation promise and that its discretion is not unfettered.

The Court unanimously set aside the trial judge's finding of an ad hoc fiduciary duty and her specific remedial directives regarding a 'fair share' of net resource revenues.

The Court also unanimously dismissed the Crown's limitations defence.

The Court split on the standard of review for historical treaties and whether the trial judge made extricable errors of law in her interpretation, but the majority upheld her core interpretation of the augmentation clause.
