Where we operate, our focus is safety and protection of the communities and environment. Extensive dialogue has taken place with landowners, neighbours, Indigenous Peoples, communities and other stakeholders and would continue throughout the construction and post-construction phases.

At the beginning of the construction, an easement and any additional temporary workspace required for construction are surveyed along the pipeline corridor. The space required varies, however, is normally less than 45 metres wide. Trees and brush are cleared. The topsoil is also removed and carefully segregated for future reclamation. Most construction at Trans Mountain’s facility sites, such as terminals or pump stations will occur on existing property or next to existing facility sites. Although each location is different, typically the site is prepared for construction using similar steps as for the pipeline corridor.

From the start of the survey to final cleanup, a particular parcel of land along the pipeline corridor would normally be disrupted for one to two months, however, seasonal changes, such as frozen soil conditions, could adjust the construction timeline. Construction at facility sites such as terminals and pump stations may take 12 months or more. Location-specific variables can impact construction. However, we make every effort to minimize impact to landowners and neighbours. Where there may be a potential public safety concern, restricted areas are established. Noise, dust, traffic, night lighting and other disturbances are limited to reduce the impact to the public and surrounding area.

Project construction activities will be planned to minimize disturbance and impact to landowners and the community. We will use trenchless construction methods in select locations to minimize potential disruption or environmental impact. We are undertaking public awareness communications to notify local communities when, where and for how long construction and/or disturbances may take place.

We will also establish a community liaison and contractor liaison during construction. The liaison will provide construction-related information along the pipeline corridor, be available to answer questions and address construction-related concerns.

Following construction, our objective is to return the temporary construction space and right-of-way to pre-construction conditions, as much as possible.

Project Timeline

The Federal Court of Appeal decision issued on August 30, 2018 cancels the Order-in-Council, which had approved a Certificate of Public Convenience and Necessity (CPCN) for the Expansion Project. 

As a result of the decision, Trans Mountain is winding down in-field construction activities in a safe, secure and environmentally appropriate manner. Learn more about the activities underway here.

On September 26, 2018, the NEB announced it will hold a public hearing to carry out its reconsideration related to the Trans Mountain Expansion Project. The Government has directed the NEB to complete the reconsideration process and issue its resulting report no later than February 22, 2019. 

On October 3, 2018, the federal government announced it will re-initiate Phase III consultations with all 117 Indigenous groups impacted by the Project.

We will provide a new Project timeline once one becomes available.
