There are of deep-water wharfage for the loading and unloading of bulk products. Marine terminals include inside and outside storage, and some of berthing space for ships carrying general cargo. The port facilities include the Cruise Ship Facility, or International Marine Passenger Terminal which was built as a passenger terminal for a ferry to Rochester, New York. The lands of the Port of Toronto used to be significantly larger. The Port Lands surrounding the facility were created by infilling the delta of the Don River by the Toronto Harbour Commission in the 1910s, and were owned and controlled by the Harbour Commission until the 1990s, when they were transferred to the City of Toronto. The lands are expected to be redeveloped into a new neighbourhood, by the Waterfront Toronto partnership. The north-east corner of the harbour, formerly housing marine terminals, is being redeveloped into the East Bayfront residential neighbourhood. The Don River mouth is planned to be 're-naturalized'.
