Meanwhile, the Chippewas of the Thames First Nation have sued the Canadian government in Canada’s Supreme Court in order to challenge the permitting process for Enbridge’s Line 9 tar sands pipeline, saying their treaty rights to consultation were not met before the pipeline was approved. If the Supreme Court rules in favor of the Chippewas, it could set a precedent requiring formal nation-to-nation consultations between the Canadian government and First Nations for all future energy projects that would affect Native land.
