When the ancestors of the Beaver Lake Cree signed a treaty with Canada in 1876, they ceded vast tracts of land in Alberta in exchange for continued rights to hunt, fish and gather plants and medicines, as they had always done. In recent years, the large-scale deforestation, wildlife disturbance and pollution resulting from tar sands developments have been eroding these treaty rights and now threaten the community’s traditional way of life.

So in 2008, they launched a legal challenge aimed at halting the wholesale destruction of their ancestral lands. It cites 17,000 infringements by oil companies of the Beaver Lake Cree’s constitutionally protected treaty rights and seeks injunctions against new developments.
