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.

Participant Funding Program

Update posted on 19 May 2017. To date PFP has awarded over 60% of the $10M. After the new Panel makes further hearing process decisions, the PFP will announce when and how to apply for the remaining funds with priority given to eligible intervenors that have no funding.

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.
