Trans Mountain is committed to working with responsible contractors. We seek out companies that share our values of safety, integrity, respect and excellence.

We expect all our contractors to work to the high standards of safety and environmental protection we set for ourselves, and to assist us in fulfilling our commitments to Indigenous communities and stakeholders. This includes our environmental commitments, respect for heritage resources and a commitment to report any environmental incident in the course of their work. To monitor adherence with our policies, we have a team of Trans Mountain employees and environmental inspectors who work alongside each contracted company.

We have selected contractors with specific experience and expertise for each unique portion of the Expansion Project.

In addition to leading construction on their portions of the Project, the contractors are responsible for hiring the majority of individuals and sub-contractors needed for the work in accordance with our commitment to maximize opportunities for Indigenous, local and regional communities.
