Canadian First Nations and U.S. tribal communities have signed a treaty to fight the development and distribution of oilsands crude from Alberta.
Indigenous leaders signed the agreement today in Montreal and Vancouver.
They say they plan to join together to prohibit and challenge the use of their lands for the expanded production of Alberta's oilsands, including distribution of crude via pipeline, rail or tanker.
They are targeting various proposed pipeline projects, including TransCanada's Energy East, Enbridge's Northern Gateway and Kinder Morgan's Trans Mountain expansion.
