Trans Mountain Expansion Project

The Trans Mountain Expansion Project (TMEP) is a proposal to expand and twin the existing Trans Mountain oil pipeline system between Edmonton, AB and Burnaby, BC. It would include approximately 980 kilometres of new pipeline, new and modified facilities (such as pump stations, tanks, tanker berths, and transmission lines), and include the reactivation of 193 km of existing pipeline.

The Canadian Energy Regulator (CER) federally regulates this project. However, the Commission is still responsible for reviewing some applications, typically related to access to lands, for the portion of the pipeline within British Columbia.

Primary Project Permits

Permits for natural gas pipelines (and related compressors, meter stations, etc.) or LNG Facilities are required before construction can start on a major project. Applications go through a thorough permitting process, described in our Permitting Process page. Approvals, issued under the Oil and Gas Activities Act (OGAA), contain specific conditions and requirements that the proponent must meet in order to be in compliance with the permit.

All Other Project Permits

There are various types of permits issued by the Commission for major projects, throughout the different phases of design and construction. Permits that have been issued to date for a particular project can be viewed below.
