The Royal York Hotel
Built on the site of the Queen's Hotel by the Canadian Pacific Railway in 1928-29, the Royal York Hotel was part of its coast-to-coast chain of grand hotels. The skyscraper hotel, designed by Montreal architects Ross and Macdonald in association with Sproatt and Rolph of Toronto, was the largest hotel in the British Commonwealth and dramatically altered the Toronto skyline. Inside, attractive rooms - from the classicism of the 1928-29 interior to the 1957-59 extension decorated in Canadian themes - have provided the setting for conventions, entertainers, cocktails, teas, debutante balls and royal visits. Together with Union Station to the south and the Dominion Public Building to the southeast, the Royal York Hotel has created one of the finest streetscapes in the provincial capital.
