Ottawa Train Station (IATA: XDS), or Ottawa station, is a Via Rail station in Ottawa, Ontario, Canada. It is located at 200 Tremblay Road and serves inter-city trains connecting it to Toronto and Montreal. OC Transpo's bus routes 61 and 62 carries railway passengers west into the city centre or east to St Laurent Station (with connections to the eastern suburbs). The former Bus Transitway station, Train Station, will reopen in 2018 as the Confederation Line LRT station named Tremblay.
The station was designed by John B. Parkin & Associates and was built in 1966. It won a Massey Medal for architecture in 1967. In 2000, the Royal Architectural Institute of Canada named the station as one of the top 500 buildings produced in Canada during the last millennium.
Ottawa’s trains once came into a large downtown Union Station a short distance from the Parliament buildings, but with the replacement of the railway tracks beside the Rideau Canal with the National Capital Commission’s Colonel By Drive scenic parkway, the former station has been converted into the Government Conference Centre.
A $21.7 million renovation project started late 2016. The project will add an elevator in the spiral ramp and at track 3 and 4, a levelled platform for track 1, and roof improvements. 
Air France–KLM runs a connecting shuttle bus from this station to Montréal–Pierre Elliott Trudeau International Airport, exclusive for the airline's customers only. As of 2016[update] Air-France KLM has three daily bus services between those cities.
