Trans Mountain Expansion Project

The Trans Mountain Expansion Project (TMX) is a proposal by Trans Mountain Pipeline ULC, a subsidiary of Kinder Morgan, to twin the existing Trans Mountain oil pipeline and expand the Westridge Marine Terminal. The existing pipeline, built in 1953, runs from Edmonton, AB, to the Westridge Marine Terminal and the Chevron refinery in Burnaby, BC. Detailed information about the project can be found on the Trans Mountain website.


The TMX project is subject to a review by the National Energy Board (NEB) under the Canadian Environmental Assessment Act, 2012 and the National Energy Board Act. On December 16, 2013, Trans Mountain Pipeline ULC filed an application with the NEB.

In accordance with the legislated time limit, the NEB submitted a recommendation report to the Minister of Natural Resources on May 19, 2016. Detailed information about the NEB’s review of the project can be found on the NEB website.

Government of Canada’s Decision-Making Process

To guide the Government of Canada’s decision-making on this project, the following measures are being taken in accordance with the principles the Government announced on January 27, 2016.

Undertake deeper consultations with Indigenous peoples

The Crown recognizes that Indigenous groups are partners in developing Canada’s resources and is committed to fulfilling its duty to consult in a meaningful and responsive manner. The Major Projects Management Office (MPMO) is serving as the Crown Consultation Coordinator for TMX and will coordinate the consultation requirements of federal departments and agencies with relevant regulatory mandates throughout the review, decision-making and regulatory phases of the project. The MPMO is the Government’s primary point of contact for Indigenous groups.

The Government will expand Crown consultations for the project and provide Indigenous groups with additional funding to support their participation in these consultations. Consultations with potentially impacted Indigenous groups are underway.  Information and feedback gathered in consultations will be consolidated to inform future decisions on the project.

Budget 2016 provides $16.5 million over three years, starting in 2016–17, to the NEB, Natural Resources Canada and Transport Canada to support public and Indigenous participation in enhanced consultations related to this project and other projects undergoing reviews by the NEB. Funding provided to the NEB will be fully cost-recovered from industry.

Facilitate further public engagement

On May 17, the Honourable Jim Carr, Minister of Natural Resources, announced that Ms. Kim Baird, Mr. Tony Penikett and Dr. Annette Trimbee would serve as his Representatives on the Trans Mountain Pipeline Expansion Project Ministerial Panel.

During the summer of 2016, the Panel engaged people from potentially affected communities close to the proposed pipeline and shipping corridors. The Panel received input through in-person and online channels, and identified relevant additional views to those already heard in the NEB Report.  View the Online Questionnaire Report.

The Panel submitted a report of their findings to Minister Carr on November 1. The Minister will use the report to inform Cabinet’s final decision on the Project, expected by December 19, 2016.  View the Ministerial Panel Report.

Assess the upstream greenhouse gas emissions associated with this project and make this information public

Environment and Climate Change Canada conducted an assessment of upstream greenhouse gas emissions (GHG) linked to the TMX project, a draft of which was posted on May 19, 2016, for public comment. After review and consideration of public comments, a final assessment will be posted.

Seek an extension to the legislated time limit for the Government’s decision on the project

To provide sufficient time for these measures, the Government of Canada intends to seek an extension of four months to the Government’s legislated time limit for decision-making (to seven months in total), changing the date for a decision from August 2016 to December 2016.
