College Park is a shopping mall, residential and office complex on the southwest corner of Yonge Street and College Street in Toronto, Ontario, Canada. An Art Deco landmark, the building was built between 1928 and 1930 by the Eaton's department store, and was designed by Ross and Macdonald (in association with Henry Sproatt), the Montreal architectural firm that also designed the Royal York Hotel and Maple Leaf Gardens in Toronto, the Château Laurier Hotel in Ottawa, and the Montreal Eaton's store.
Eaton's began secretly assembling land at Yonge and College Streets in 1910 for a new store. The First World War put the plans on hold, but Eaton's retained the land. During the 1920s, plans were made to shift all Eaton's operations from their existing location at Yonge Street and Queen Street West to the College Street site. Eaton's even offered to sell part of its landholdings to its main competitor, Simpson's, in an effort to shift the heart of Toronto retailing northward and to preserve the synergy created by having two retail giants next to one another. The effort was unsuccessful, and Simpson's chose instead to expand its Queen Street store.
In 1928, Eaton's announced plans for the largest retail and office complex in the world to be constructed on the site, featuring 5,000,000 square feet (465,000 square metres) of retail space and a 38-storey 1920s era skyscraper. Just as the war had intervened a decade earlier, however, the Great Depression curtailed the grandiose plans for the site. The first phase of the project, a department store of 600,000 square feet (56,000 square metres), was the only part of the complex that was ever built. Nevertheless, foundation pillars, 10 feet in diameter, were driven 30 feet down into bedrock during the construction of the first phase to accommodate the tower. On October 30, 1930, the new store was opened by Lady Eaton, the matriarch of the Eaton family, and her son John David Eaton, the future president of the company.
