Exhibition Place is a mixed-use property on the Toronto shore of Lake Ontario, a few kilometres west of the central business district. The 197–acre area features expo, trade, and banquet centres, theatre and music buildings, parkland, sports facilities, and a number of civic, provincial, and national historic sites. From mid-August through Labour Day each year, the Canadian National Exhibition (CNE), from which name Exhibition Place is derived, is held on the grounds. During the CNE, Exhibition Place encompasses 260 acres (1.1 km), expanding to include nearby parks and parking lots. The CNE features games and a midway, among a host of attractions. The fair is one of the largest and most successful of its kind in North America, and an important part of the culture of Toronto, the province, and the nation itself. The grounds have seen a mix of protection for heritage buildings along with new development. Five buildings on the site (the Fire Hall/Police Station, Government Building, Horticulture Building, Music Building and Press Building), all designed by George Gouinlock, were designated a National Historic Site of Canada in 1988.
