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 Ontario Energy Board has issued the Notice of Application and Letter of Direction for the Leave to Construct Application proceeding for the Project. The Notice, application and evidence submitted by NextBridge is available here.

NextBridge posts the Environmental Assessment Report for the Project. The Environmental Assessment Report can be viewed here. As part of the submission process, interested stakeholders and communities were encouraged to submit comments to the Ministry of the Environment and Climate Change by September 12, 2017. NextBridge is currently reviewing and responding to comments and intends to submit an amended Environmental Assessment.
