The Beaver Lake Cree Nation (BLCN) territory in Treaty 6, spans 38 972 square kilometers and is in the heart of the Alberta Tar Sands, which have been called “the largest – and most destructive – industrial project in human history” . Living in “the middle of the biggest sacrifice zone on Earth”, this community has been resisting ongoing violation of their treat rights, by taking legal action against the provincial and federal government over the cumulative impacts to their lives and ecosystems . The governments have leased out much of BLCN’s land to oil companies without any prior consultation or approval from the BLCN. They have authorized 300 projects representing 19,000 individual authorizations related to oil and gas, forestry, mining and other activities BLCN lands . The territories host about 35,000 oil and natural gas wells, a Canadian Forces base, and thousands of kms of pipelines, access roads, and seismic lines. While the BLC say that while ecosystems are rapidly declining, the government has plans to triple bitumen extraction . These projects are destroying the lands, polluting waters, poisoning animals and rendering BLCN’s food sources inedible. “Most significantly, caribou herds in the BLC territories are disappearing fast…With oil in the water table, with animals being poisoned, with forests being so fractured that it no longer supports any of the fur bearers or other animals that First Nations depend on for food” . “Indigenous rights are the last stronghold against the unmitigated expansion of the tar sands at source. The BLC are carrying a case on their backs that could set historical precedence: success would mean that it would become much harder if not impossible to expand tar sands projects and would greatly curtail the industry’s expansion plans” .
