Public Comment Period – Trans Mountain Expansion Project

As directed by Governor in Council (GIC), the NEB has issued a Certificate and Amended Certificates to Trans Mountain Pipeline ULC (Trans Mountain). The issuance of Certificates does not automatically reinstate previous NEB decisions or orders required for Trans Mountain to begin or resume construction.

On June 21, 2019, the NEB issued a letter [Filing C00072] setting out a public comment period on a proposed approach that could be followed to resume the regulatory processes for the Trans Mountain Expansion Project (Project), including:

Anyone may comment on any of the regulatory processes listed above and may wish to review the corresponding attachments that provide details about the status of the various regulatory processes, with links to relevant documents. These documents are intended to help inform your comments, which can be submitted online, via fax or mail until July 5, using the comment form [PDF 221 KB] [WORD 33 KB].

Following the comment period, the Board will decide how regulatory processes will be resumed.

The NEB recognizes that that the matters which are the subject of this comment period are unique and complex, and the volume of information is significant. A list of Frequently Asked Questions may be of assistance, and Process Advisors are available to assist the public with any process-related questions by phone at 1-800-899-1265 (toll-free) or by email at
