The Financial Post reports in its Saturday edition that the federal government is studying the best options for indigenous communities to reap economic benefits from the Trans Mountain pipeline, but Ottawa is not planning to sell the project while legal and political risks remain. A Canadian Press dispatch to the Post reports that the Supreme Court of Canada eliminated one of those risks Thursday when it denied British Columbia the right to regulate the contents of the pipeline. At least two other legal challenges hang over the project, leaving its future in doubt. Both question the validity of the cabinet endorsement given to TMX, one citing green concerns and the other mistakes made during talks with indigenous communities. There are at least three indigenous groups vying to buy TMX, but its not yet for sale. There are 129 indigenous communities potentially impacted by the pipeline, and not all of them are part of three well-organized groups. Some groups are working to stop TMX. Last summer officials at the Department of Finance held an "initial engagement" with nearly six dozen indigenous communities. It is now working to refine the potential models for indigenous participation raised in those consultations.
