- GO Expansion
More trains, less waiting
With the GO Transit service area – which includes the Greater Toronto and Hamilton Region (GTHA), Kitchener-Waterloo, Barrie and Niagara – expected to grow to 15 million people by 2051, expanding GO service is necessary to help alleviate congestion and offer customers an option that will be more desirable than driving.
Enter GO Expansion – the program that will bring faster, more frequent train service by delivering new transit infrastructure and operational plans that will reduce journey times, add capacity and further improve on-time performance and customer satisfaction.
