Now Under Construction

Year after year, train by train, bus by bus, Metrolinx has steadily increased GO Transit service. And now, that work is taking on a whole new energy. We’re building transit service that will change life in this region through the GO Expansion program. More than a rush hour commuter service, GO will offer more service with faster trains, more stations and seamless connections to a regional rapid transit network.

GO Expansion will make the network better, faster and the region easier to travel in.

The GO Expansion program will provide a range of improvements across the GTHA.

We’re experiencing incredible growth, with an estimated nine million people calling our region home by 2041. Growth means opportunities – for careers, for families, for entertainment and everyday life. It must be matched by a transit system that keeps pace with changing realities. Today, we run 1,500 weekly trips on the GO Transit system. Each year we’re adding more, and when we’re done building, we’ll be running over 6,000 weekly trips.

The Greater Golden Horseshoe needs more rapid transit options than ever before. GO expansion will take you more places than ever before, will get you there faster, and will give you more options to connect seamlessly to the network of subways, light rail transit and buses throughout the region.

How do we take a rush hour commuter service to the next level? It’s about more than just the number of trips. Using a new train technology on the Barrie, Lakeshore, Stouffville and Kitchener lines will allow faster trains to transport you and will offer all-day trips, going two ways, as quickly as every 15 minutes. Milton and Richmond Hill lines will also offer you up to 30% more service.

Everyone in the Greater Golden Horseshoe, from east to west, north to south, will benefit from this expansion of GO service.
