Environment committee  Thank you, Mr. Chair. The Mikisew Cree have submitted on many occasions to the governments of Alberta and Canada concerns regarding the pace and extent of oil sands development. Unfettered exploitation of oil sands with little to no regard to the Mikisew Cree's concerns and claims have left the first nation to conclude that both levels of government have de facto extinguished the treaty rights of the Mikisew Cree.
