SA Energy is a member of the Pipeline Contractors Association of Canada. Trans Mountain did not explain why two of the contracts with SA were terminated. 'Insist' on safety "We do not wish to comment on the terms of our contractual relationships with contractors," Trans Mountain said this weekend. "What we can say is that Trans Mountain is committed to a strong culture of safety above all else and insist that our project contractors and subcontractors are equally committed." Trans Mountain also ended its contract, a joint venture, with Spiecapag Canada Corp. and Fort St. John's Macro Enterprises Inc.
