Toronto's current Union Station was constructed between 1914-1920 by the Toronto Terminals Railway. It was officially opened to the public on August 6, 1927. Union Station has been designated a National Historic Site of Canada since 1975, and a Heritage Railway Station since 1989. Toronto's Union Station is the largest and most opulent railway station in Canada. It has even appeared in movies and TV shows, a lot of times representing settings in other cities. This station is the busiest transportation facility in Canada, serving over 250,000 passengers a day. Renovations to Union Station started in 2010, they were completed in 2017. The big differences are the new glass roof over the passenger platforms and railway tracks. These will allow for more natural lighting. There is also a plaza for public events being created between Union Station and the Royal York Hotel.  More than 160 panels of public art are being installed.
