GO Transit is a regional public transit system serving the Greater Golden Horseshoe region of Ontario, Canada.
With its hub at Union Station in Toronto, GO Transit’s distinctive green and white trains and buses serve a population of more than seven million across an area over 11,000 square kilometres (4,200 sq mi) stretching from Brantford and Waterloo in the west to Newcastle and Peterborough in the east, and from Barrie in the north to Niagara Falls in the south. GO Transit carried 68.5 million passengers in 2017, and its ridership continues to grow.
GO Transit operates diesel-powered double-decker trains and coach buses, on routes that connect with all local transit systems in its service area, as well as Via Rail, Canada's national rail system.
