The Union Station Enhancement Project includes the design and construction of transit infrastructure and upgrades at the southernmost part of Union Station, including the addition of new tracks, the expansion of platform 24/25, a new south platform, and a new south concourse. These enhancements are being made to accommodate GO rail service increases, improve customer experience and enable the planned GO Expansion program.

Union Station is a big part of Toronto’s history. The current building opened its doors in 1927, although its history dates back to 1858 with the debut of the first of three stations. The Union Station we know today was designed in the École des Beaux-Arts style by a team of architects from the Montreal Firm of G.A. Ross and R.H. Macdonald, Hugh Jones of the CPR and John M. Lyle of Toronto. The Canadian Pacific Railway and Grand Trunk Railways commissioned its construction. In over 150 years, Union Station has survived the Great Toronto Fire of 1904, hosted concerts, appeared as the backdrop in feature films, and most of all, served travellers near and far. 



Both the City of Toronto and GO Transit have been sharing ownership of Union Station since 2000. The City of Toronto owns the bulk of the station building, while the train shed, platforms, tracks, and newly renovated York Concourse are owned by GO Transit.
