In its recent decision in Keewatin v. Minister of Natural Resources ("Keewatin"), the Ontario Superior Court of Justice held that the Province of Ontario does not have the authority under either Treaty 3 (described below) or the Constitution Act, 1867 to "take up" tracts of land for forestry within lands subject to Treaty 3 that were added to Ontario in 1912 (the "Keewatin Lands") so as to limit the right to hunt and fish guaranteed to the plaintiffs under the Treaty.
