Spring 2018 – Summer 2019

Draft‑design studies and the public consultation process*

Hydro‑Québec is committed to working with the community for the duration of the project. Our team has pledged to keep the dialogue open with the local population at every stage of development.

Since 2018, we have repeatedly met with community representatives (MRCs, municipalities, regional organizations and regional branches of the different government departments affected by the project) as well as with many of the landowners affected by the proposed line route. Our aim has been to record their concerns, take them into account and make adjustments to the project wherever possible.

This kind of approach helps us come to the best solutions together.

Summer 2019 – Fall 2020


Hydro‑Québec filed an environmental impact assessment (in French only) for the project and various applications for government approvals.

The interconnection line will be subject to the provincial environmental impact assessment and review procedure (in French only), which includes a review by the Bureau d’audiences publiques sur l’environnement (in French only) (office for public hearings on the environment) as well as an analysis by the Canada Energy Regulator, given that the power line will cross an international border.

Summer 2023–fall 2025
