Chorley Park
Chorley Park was originally the property of Toronto Alderman John Hallam, born in Chorley, Lancashire. In 1911 the garden provided the setting for Ontario's last Government House, which was designed by F.R. Heakes and built of Credit Valley stone in the French Chateau style. The house stood at the end of a curving approach from Roxborough Drive. From 1915 it was the imposing official residence for five Lieutenant-Governors, where distinguished visitors and Toronto citizens attended levees, receptions and charity balls, until closed for financial reasons in 1937. Acquired by the government of Canada, it served as a military hospital from 1940 to 1953, and later as RCMP headquarters and for Toronto Militia purposes. Chorley Park was purchased by the City of Toronto in 1960 and the building was demolished a year later when the site was developed as a public park.
