This dispute is serious although not nearly as serious as the dispute between Canadian energy companies and the Liberal Government which has decreed that no new pipelines will be built in Canada under their reign. The cost of this  Liberal Government behavior toward Western Canadians energy workers will far exceed the cost to Canadians of the Boeing / Bombardier dispute. Bombardier still has every other nation in the world to sell their C series planes too. Canadian energy companies have no pipelines to tide water or to Eastern Canada to sell their oil and gas.
