Yorkville Plaza is a 31-storey condominium tower and former hotel in Toronto. The hotel was developed by Ian Richard Wookey, who purchased the Yorkville property in 1966 and hired architects Webb Zerafa Menkès to design the building, which was named the Continental Plaza provisionally. Shortly before construction began in the fall of 1969, Wookey sold the project to a partnership of Hyatt and Great West International Equities, the latter of which was taken over in 1971 by Trizec. In the spring of 1972, the hotel opened as the Hyatt Regency.
The hotel was, after York Square, the second building project planned by Wookey in Yorkville and played a major part in his renewal programme for the neighbourhood. Wookey would partner with Webb Zerafa Menkès again in the 1970s to build Cumberland Court and Hazelton Lanes, thus solidifying the architects' role in defining the character of Yorkville. The hotel became a focal point of Toronto society and hosted dignitaries and celebrities frequently. Additionally, the building became one of the city's iconic works of brutalist architecture.
The Hyatt Regency operated from 1972 until 1978, when Four Seasons purchased the management rights. Subsequently, Four Seasons ran the hotel until it closed in 2012. In 2011, the building had been purchased by Camrost-Felcorp, led by developer David Feldman. After the closure, the new owners gutted the hotel and converted it to condominiums. As part of the conversion, new buildings were constructed to the east and south of the hotel in place of the former ballrooms. The new complex of condominiums was named Yorkville Plaza.
