What type of work is happening? 

During the closure, crews are conducting foundational work for a second track and line improvements, including installing culverts, utilities, and signalling works. As part of GO Expansion, crews are also carrying out work at Aurora GO Station, the future Bloor-Lansdowne GO Station and completing essential maintenance on the Barrie line. 

Metrolinx is supporting the life you lead by bringing you all-day, two-way GO train service that fits your schedule. Whether you’re in Toronto, York Region or Simcoe County, life can be busy. You’ve got a lot on your plate, and you’re looking for balance – you’re looking for easier ways to seamlessly get where you need to go. That’s what the Barrie line GO Expansion will offer. From Lake Simcoe to Lake Ontario and everywhere in between, we’ve got you covered.

GO service is expanding to serve you better, with more frequent service, more stations, and more connections. Metrolinx is transforming GO Transit to bring more frequent two-way, all-day service to the Barrie line, seven days a week.

To keep these plans on track, we sometimes work overnight and on weekends, building and updating rail infrastructure, renovating GO stations, building new train platforms and more. Learn more about GO Expansion.

We aim to provide you with plenty of notice when we need to adjust service for construction activity. Please plan your trip in advance.
