GO Transit is Canada's first, and Ontario's only, interregional public transit system, linking Toronto with the surrounding regions of the Greater Toronto Area (GTA). We carry 45 million passengers a year in an extensive network of train and bus services that is one of North America’s premier transportation systems. Since we began operating in May 1967, more than three-quarters of a billion people have taken the GO Train or the GO Bus. Officially known as the Greater Toronto Transit Authority (GTTA), GO Transit provides safe, convenient, and efficient transportation to the communities of the Toronto area.
GO Trains and GO Buses serve a population of more than five million in an 8,000-square-kilometre area (3,000 square miles) extending from downtown Toronto to Hamilton, Milton, and Guelph in the west; Orangeville, Barrie, and Beaverton to the north; Stouffville, Uxbridge, and Port Perry in the northeast; and Oshawa and Newcastle in the east. The buses widen our service as far as 100 kilometres (over 60 miles) from downtown Toronto. We connect with every municipal transit system in the Greater Toronto and Hamilton areas, including the Toronto Transit Commission (TTC).
The Greater Toronto Area consists of the City of Toronto and the surrounding Regions of Halton, Peel, York, and Durham. GO Transit also serves the neighbouring City of Hamilton, and reaches into Simcoe, Dufferin, and Wellington Counties.
Our seven train lines are Lakeshore West, Milton, Georgetown, Bradford, Richmond Hill, Stouffville, and Lakeshore East. At peak rush-hour periods, train service is available at all stations.
In weekday off-peak hours, trains run only on the Lakeshore between Oshawa in the east and Burlington in the west, and on the Georgetown line between Union Station in the east and Bramalea in the northwest. On weekends, trains run only between Pickering in the east and Oakville in the west. Bus connections extend our Lakeshore service to Newcastle in the east and Hamilton in the west.
Off-peak GO Buses between Union Station and other train stations (sometimes nicknamed train-buses) give passengers more choice when travelling to and from downtown Toronto before and after rush hour when the trains aren’t scheduled to run, even on weekends. More riders are choosing Union Station buses because they appreciate having the flexibility of travelling one way by train and the other by bus.
