Project information

This new 12.5-km long railway line will pass through the municipalities of Nantes, Lac-Mégantic and Frontenac, specifically between mileage point 113.27 of the Moosehead subdivision and mileage point 3.49 of the Sherbrooke subdivision. The project also includes building two (2) yard tracks in the Lac-Mégantic industrial park to allow for the relocation of the Nantes and Frontenac railway operations to this location, . At the end of the project, the existing track that runs through the center of Lac-Mégantic including the sidings, will be dismantled.

Invitation to comment

During the consultation period, from October 24 to November 25 2022, the public will be invited to submit written comments on:

  • The hydrogeological report and the assessment of the potential impacts of the project on groundwater and wetlands; and
  • The proposed mitigation and follow-up measures to minimize environmental impacts.

All written documents, comments and communications sent to TC will be considered public documents. A summary or excerpts of the comments, including the name of the author, may be published in a consultation report and on our website. Comments will also be shared with the Canadian Transportation Agency as part of the project's application.
