Prior to 1999, Toronto's harbour was managed by the Toronto Harbour Commission (THC), created by a federal act in 1911. At first, the Commission managed the harbour as well as waterfront lands across the then City of Toronto beyond the harbour area, including the Sunnyside waterfront area, east of the Humber River. Over time, the facilities and lands other than the inner and outer harbour and the airport were transferred to the management of the City of Toronto and other authorities, leaving the THC to manage the airport and harbour. The THC received lease revenues and subsidies from the various governments to carry on its activities.
