The Projects

Energy East

Energy East is a 4,500-kilometre pipeline proposed to carry 1.1 million barrels of crude oil per day from Alberta and Saskatchewan to refineries in Eastern Canada.

The project would include:

  • Converting an existing natural gas pipeline to an oil transportation pipeline;
  • Constructing new pipeline in Alberta, Saskatchewan, Manitoba, Ontario, Québec and New Brunswick to link up with the converted pipe; and
  • Constructing the associated facilities, pump stations and tank terminals required to move crude oil from Alberta to Québec and New Brunswick, including marine facilities that enable access to other markets by ship.

Eastern Mainline

The Project would consist of approximately 279 km of new gas pipeline and related components and would be constructed in four sections, beginning near Markham, Ontario and finishing near the community of Brouseville, Ontario. About 203 km of the proposed 279 km pipeline would be installed adjacent to existing pipeline, railway and public highway rights-of-way.

The application for the Project has been filed to enable TransCanada to continue to meet its commercial obligations following the proposed transfer of certain Canadian Mainline facilities to Energy East Pipeline Ltd. for the conversion of those facilities to crude oil from natural gas service (Asset Transfer). The Asset Transfer makes up a portion of the Energy East application.

TransCanada is not, in this application, seeking approvals pursuant to Part IV of the NEB Act, relating to recovery of the cost of the Project through tolls.

Regulatory Documents

During the Hearing Panel review of these projects, all evidence, letters of comment, decisions and other relevant documents must be filed with the NEB and placed on the online document repository. These documents are all accessible to the public. You can find these documents at:

The Lists of Issues are the regulatory documents that outline what the Hearing Panel will consider when it reviews the Energy East and Eastern Mainline projects. They keep everyone focused on the issues that are relevant to the Hearing Panel’s assessment.

Frequently Asked Questions

Comprehensive Review Process

The review process includes the following three streams:

  • Panel Hearing for Aboriginal groups and stakeholders directly affected by the projects and/or who have relevant expertise
  • Expanded public engagement activities to be carried out by a team of Board Members who will report relevant findings to the Hearing Panel
  • An assessment of upstream greenhouse gas emissions (GHGs) to be conducted by the Government of Canada

This diagram provides a high level overview of the main activities of the comprehensive review process. For more information about these initiatives, please see this backgrounder.

Comprehensive Energy East Review Process

The review will include three streams:

First stream: NEB Panel Hearing

It will start with Panel Session in communities between August and December 2016.

Later on in 2017, the steps are:

  • Evidence filed and questioned
  • Comments provided
  • Draft conditions
  • Final argument

The final Hearing Panel recommendation report is due in March 2018.

The second stream is led by Additional Board Members.

It starts in the fall of 2016 with engagement activities, to be followed by community meetings in the winter and spring of 2017, and a report to the NEB Hearing Panel in the spring of 2017.

The third stream is an assessment of Upstream

Greenhouse Gas Emissions (GHGs).

The draft GHGs report, and public consultation and engagement activities will be conducted in 2017.

The final GHFs report is due in March 2018.

Note: This diagram will be updated periodically as information becomes available.

Panel Hearing (Stream #1)

Support for Participants

Participant Workshops

Participant workshop, Part 1 (intervenors): How to prepare for the Panel Sessions

The purpose of these workshops is to provide intervenors with information on what to expect and how to prepare for the upcoming Panel sessions. The presentations last between 30 and 40 minutes, and each one will be followed by a question period. Additional sessions could be scheduled based on demand.

Process Advisors

The main role of a Process Advisor is to provide information to the general public and support to participants in the hearing. They can also answer questions about the NEB’s process. To reach a Process Advisor for Energy East or Eastern Mainline call 1-800-899-1265 or email:

Participant Funding Program

Refer to the Participant Funding Program page for information on deadlines, eligibility, how to apply for funding and how to submit claims.

Oral Traditional Evidence

The NEB is committed to hearing from Indigenous peoples in a way that respects their values and traditions. Indigenous peoples have an oral tradition for sharing lessons and knowledge from generation to generation. Since this information cannot always be shared adequately in writing, the Hearing Panel has invited Aboriginal Intervenors to provide Oral Traditional Evidence.

OTE sessions for the Energy East project were held between November 9 and December 15, 2015. Additional sessions will be scheduled in 2016 and 2017.

Regulatory documents relevant to oral traditional evidence:

  • 16 July 2015: Letter to Parties, List of Aboriginal Intervenors and Notice of Intent to Provide Oral Traditional Evidence [Filing A71289]
  • 7 August 2015: Energy East and Eastern Mainline – Oral Traditional Evidence [Filing A71675]
  • 1 October 2015: Procedural Direction No. 1 – Oral Traditional Evidence Process and Schedule [Filing A72951]
  • 2 November 2015: Procedural Direction No. 2a – Oral Traditional Evidence – Regina [Filing A73650]

Official Languages

The NEB takes its obligations under the Official Languages Act seriously, and often exceeds those obligations. The NEB values Canada’s linguistic duality and enables participation in its review processes in both official languages. The NEB is committed to serving all citizens respectfully, effectively and courteously. In the case of the Energy East review, the following measures will be used to ensure effective and meaningful participation:

  1. Individuals have the right to communicate with the NEB, in writing or orally, in the official language of their choice.
  2. The NEB will always offer its services in both official languages.
  3. Simultaneous interpretation will be available for all in-person Panel Sessions and other engagement opportunities.
  4. The French version of the Energy East application available on the Energy East website can be used and relied upon to participate in both the review conducted by the NEB Hearing Panel and other engagement activities.
