As defined in Canadian common law, an exclusive aboriginal right to land based on traditional occupation and use of a portion of the territory of Canada. From: Delgamuukw v. British Columbia  5 W.W.R. 97, 104 D.L.R. (4th) 470. As aboriginal title is considered in Canadian common law to be alienable only to the Crown, it is consequently not registrable under Land Titles Acts based on the Torrens system. From: Cook v. Beckman (sub nom. Lac La Ronge Indian Band v. Beckman)  4 W.W.R. 211.
