The Toronto Harbour Commission (THC) was a joint federal-municipal government agency based in Toronto, Ontario, Canada. The agency managed Toronto Harbour as well as being responsible for major works along the Toronto waterfront. It built both Malton Airport and the Toronto Island Airport in 1939. The agency was founded in 1911 and operated until 1999 when the port operations were transferred to the new Toronto Port Authority (TPA), now PortsToronto.
