Project calendar

The tasks and timelines for the project are presented below:

Project consultation

Indigenous and community engagement

For new construction projects, the collective input from Indigenous communities and Métis, government agencies, municipalities, stakeholders, the public and landowners play an integral role in the route and site selection process.

Prior to construction, public input is obtained to ensure that the community is advised of the proposed project, and to involve the public in the decision-making process. Public consultation is a key component of the Environmental Report.

By providing the public with an opportunity to receive information about the project, the consultation program helps identify and address stakeholder concerns, and allow for meaningful participation into the project review and development process.

Public input from consultation was used to help finalize the project and mitigation plans to be implemented during construction.
