NextBridge Infrastructure (NextBridge) is a partnership between affiliates of NextEra Energy Canada, Enbridge Inc. and OMERS Infrastructure, established to participate in the Ontario transmission market. Collectively, the partnership submitted a proposal to the Ontario Energy Board (OEB) for the planning, development, construction, ownership, operation and maintenance of the East-West Tie (EWT) transmission project (the Project) in Northern Ontario. On August 7, 2013 NextBridge was designated by the OEB to develop the EWT line and to file a leave-to-construction application.

The Project is an approximately 450 km double-circuit 230 kilovolt transmission line from the Wawa Transformer Station (TS) to the Lakehead TS in the Municipality of Shuniah, near Thunder Bay, ON, with a connection approximately mid-way at the Marathon TS. The Project will also require new and improved access roads and temporary laydown and work areas.

The Ministry of the Environment and Climate Change approved the Terms of Reference for the new East-West Tie Project Individual Environmental Assessment on August 28, 2014. NextBridge has commenced and is continuing with activities supporting the Environmental Assessment under the Environmental Assessment Act for the new East-West Tie Project.


The review period for the amended Environmental Assessment closed on March 29, 2018. Thank you for providing your comments on the report.

On February 15, 2018, Hydro One Networks Inc. submitted an alternate Leave to Construct application for the EWT Line Project to the Ontario Energy Board. Hydro One’s proposal is called the Lake Superior Link. NextBridge is committed to construction and operation of the East-West Tie project and continues to work toward a 2020 in-service date.

The NextBridge’s East-West Tie project has received support from local communities and Indigenous groups. Select media coverage and documented support related to the NextBridge EWT Line Project can be viewed on the News & Updates page.
