Metrolinx, an agency of the Government of Ontario, is working to provide residents and businesses in the Greater Toronto and Hamilton Area (GTHA) with a transportation system that is modern, efficient and integrated. The Big Move is Metrolinx's bold 25-year plan to implement a common vision for transportation in the GTHA. Currently Metrolinx is made up of three operating divisions: - GO Transit, the regional public transit service, - Union Pearson (UP) Express, is a premium express rail shuttle service between Union Station in downtown Toronto and Pearson Airport. - PRESTO, an electronic fare card that allows riders to transfer seamlessly across multiple transit systems.
