Detailed Route Hearing for Trans Mountain Expansion Project is Complete

November 12, 2021

On September 22, 2021, the Canada Energy Regulator (CER) issued the final order [Filing C15038] approving all 1,147 kilometres of the project’s detailed route.

When a pipeline project starts, the company proposes the general location for the pipeline. Over time, and after many assessments, studies and broad consultation, that wide corridor becomes smaller and smaller until a precise location is determined. This final location is called the detailed route.

The detailed route hearing allowed the panel to listen to and consider people’s concerns around the route the company proposed. CER experts in engineering, environmental protection, socio-economic, safety and emergency management assessed the line from the conceptual corridor to the detailed route.

Throughout the hearing there was extensive consultation with Indigenous communities, local governments, landowners and community residents. The diverse perspectives of everyone who participated in this process helped the CER finalize the exact placement of the pipeline and the most appropriate methods and timing of construction.

The Government of Canada approved the pipeline in June 2019.

Before starting any new construction, Trans Mountain must satisfy pre-construction conditions and any regulatory requirements of other municipal, provincial or federal governments. The company expects the pipeline to be in service in late 2022.
