Metrolinx GO Expansion (Rail Electrification) Utility Relocation Project 2025 Planned Construction

Metrolinx is expanding to serve you better, with more frequent service, cleaner technology and transforming GO Transit to bring more frequent two-way, all-day service to the Barrie line, which serves the Newmarket community. The Barrie Go line expansion will provide easier ways to seamlessly get where you need to go.

As part of the project to facilitate the electrification of the provincial Metrolinx GO Expansion program, NT Power must relocate existing electricity distribution lines across the railway tracks at multiple locations to allow for the removal of any conflicts with overhead cables running over the Barrie corridor, ensuring future support for electrification.

What to Expect:

• Due to the nature of the work, there will be construction-related noise and dust from equipment and trucks. Every effort will be made to minimize these disruptions.

• Once work begins, the public can expect limited access to sidewalks, pathways, and reduced lanes in and around the construction area. Signage will be placed to inform residents of lane closures and detours around the work zone.

• Planned hydro outages may occur during construction as hydro wires are relocated. NT Power will notify all businesses and residents in the affected area about planned outages. For guidance on preparing for a power outage, visit the Government of Canada’s Get Prepared Webpage.

NT Power will continue to provide live updates on its website and social media platforms, allowing customers to track changes to scheduled outages. For more information, please visit Newmarket Construction Projects, Newmarket Outage Dashboard (arcgis.com)
