Based on E.J. Lennox's landscape scheme of 1876, this oval-shaped park in the heart of Toronto is the setting for Ontario's Parliament and nearby government buildings. To the west and east sprawls the University of Toronto, Canada's largest institute of higher education, perhaps best known for its medical school where, in 1921, Frederick Banting and Charles Best succeeded in isolating insulin. To the south, the curved, mirrored, multistoried headquarters of Ontario Hydro (1975, Kenneth R. Cooper) rises above the surroundings. The building has no furnace or heating plant; instead, energy given off by artificial lighting, equipment and people is stored in thermal reservoirs in the basement and recirculated.
