The creation of the historic district was through the Ontario Heritage Act, and was enacted by Toronto City Council in July 2006. Given its overlap with the Financial District, the historic district is an eclectic collection of buildings, with structures dating from the 1850s to the present day. Historic buildings within this district include the Dominion Public Building, and The Toronto Club. Design Architecture Shortly after acquiring the property, Canadian Pacific Hotels, a division of the Canadian Pacific Railway, announced its plan to demolish the Queen's Hotel in order to construct a new hotel. The building was designed by a Canadian architectural firm, Ross and Macdonald, in association with Sproatt and Rolph. Both firms had designed buildings for Canadian Pacific Hotels prior to the Royal York Hotel. The building design went through several drafts before its final draft, "H plan," was adopted. The plan saw the development of a towering central element, in an effort to distinguish itself from the buildings of the nearby Eaton's Annex. The building's towering design also enabled most rooms and public spaces to face either the downtown core of the city, or the Toronto waterfront and Lake Ontario. Completed in 1929, the Châteauesque-styled hotel includes a row of pointed arches on the third story and a small peaked roof with tiny dormers at the top of the pitched roof. In addition, grotesques shaped as griffins are present at various corners of the hotel. The building's exterior is made of Indiana Limestone, which encases the hotel's 28-story steel frame. Along with traditional features found in most Chateauesque-styled hotels, the building also incorporated an Art Deco setback and Romanesque-inspired decor. The balanced design of the building (prior to the addition of the east wing) was achieved through the application of semi-neoclassical motifs, and groups of arcaded windows. The interior of the building was largely created in an Edwardian architectural style. Its interior features a number of crystal chandeliers, and a hand-carved wood lobby ceiling. The building stands , containing 28 floors primarily made up of guest rooms and other hotel amenities. After the building's completion, it was briefly the tallest building in the British Empire, and Canada. The building would lose the record the following year, with the erection of the nearby Canadian Bank of Commerce Tower on King Street. Work to enlarge the hotel commenced in 1957, and was completed in 1959. The new east wing
