Toronto Harbour Commission
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.

History to 1910

The Harbour Commission was the third organization to manage the Port of Toronto, after the Commissioners of the Harbour of Toronto, known as the Harbour Trust, formed in 1850. Prior to 1850, the harbour had had three commissioners appointed by the province of Upper Canada to oversee harbour works, in conjunction with the building of the Queen's Wharf, at the foot of Bathurst Street in 1833. One of the commissioners, Hugh Richardson, was named Toronto's first Harbourmaster in 1837 and he imposed wharf fees to pay for the Wharf.

The Harbour Trust was formed in 1850 at the suggestion of the Toronto Board of Trade. On behalf of port users, the Board expressed complaints in the operation of the provincial commission, which made no improvements in the harbour. The harbour was beset by silting problems which needed to be rectified. This second commission was governed by a five-man board, two from the City of Toronto, two from the Board of Trade and a fifth appointed by the province of Upper Canada, nominated by the four other members. The first work it undertook was to remove "certain stones now lying in the channel in front of the Queen's Wharf."

The Harbour Trust was also given authority over the Esplanade plan. The original 1817 plan intended to build a public walk and garden along the waterfront, just south of Front Street. The province's plan was largely ignored and the City allowed the use of the shoreline to be used for wharves and docking. In 1837, a new plan was developed for the Esplanade. In this plan, the Esplanade would be built just south of Front, and the waterfront extended south to the "Windmill Line", some 100 yards south. The new lands would be used for port uses. The Esplanade itself would become mostly railway lands.

The intrusion of the railways into the waterfront in the 1850s to 1890s period started to crowd out recreational uses. In 1892, a legal agreement solidified the railways' usage of the waterfront. In 1893, a new plan was developed to extend landfill another  south, and a new Lake Street (today's Lake Shore Boulevard) established along the then-current waterfront edge. The problem of silting, and the increasing amount of sewage being dumped in the harbour, required ongoing dredging efforts. Other works by the Harbour Trust including a breakwater at the Don River and a breakwater at the Queen's Wharf to protect the entrance to the harbour.

The wetlands of the Don River were becoming increasingly polluted. Plans were developed to convert the area (1,000 acres in size) into usable lands. A planning advocacy group, the Civic Guild unveiled a plan in 1909 which advocated industrial and recreational uses for the land. The Board of Trade advocated the reclamation and infilling of the wetlands for port and industrial uses. The existing port facilities were inadequate when a railway strike occurred in 1910, forcing vessels to wait days to dock.

Development from 1911
A referendum was held on January 2, 1911, to approve a new 'Toronto Harbour Commission' to take over the harbour and waterfront. The Toronto Telegram newspaper exposed the decrepit condition of the old harbour facilities, and the City and Board of Trade wanted a new Commission set up, similar to the Montreal Harbour Commission of 1908, with much-expanded powers over the Harbour Trust. The referendum was passed overwhelmingly.

The Government of Canada established the Toronto Harbour Commission on May 19, 1911 by an Act of Parliament. The commission was to manage Toronto harbour and waterfront lands in Toronto and provide for their improvement. Its initial plans included the cleanup of Sunnyside Beach, and a breakwater from the Humber River to Bathurst Street. In the central core, the Commission infilled lands south of Harbour Street to their current waterfront line. To the east, the Commission infilled the lands of the Don River marsh, for use as industrial and port lands. The bulk of these works were completed by 1925.

The Harbour Commission was the landlord for most of the Sunnyside Amusement Park at Sunnyside. After the Gardiner Expressway was built, the Harbour Commission transferred the Sunnyside lands to the City of Toronto.

In later years, the agency was responsible for the infill of Hanlan's Point on the Toronto Islands to build the Island airport. The agency also infilled the lands south of Lake Shore Boulevard south of the Canadian National Exhibition.

In the 1990s, the agency was requiring annual subsidies to manage the Island airport and the port lands. There were a number of harbour commissions in Canada and the federal government replaced the law under which harbours were managed, with the Canada Marine Act. Most ports were put under the authority of local governments and several were put under the authority of new 'Port Authority' agencies which would manage their affairs on a break-even basis. Toronto's was added to the Port Authority program, largely at the insistence of local Liberal MP Dennis Mills. In 2001, the new Toronto Port Authority was formed to manage the Port of Toronto, including the Island airport.

Also in the 1990s, the Harbour Commission transferred the Don River infill lands to the City of Toronto Economic Development Commission in exchange for an annual subsidy. In the 2000s, the Toronto Port Authority sued the City of Toronto for $1 billion over the lands, claiming that the lands were transferred illegally. The Authority and the City settled out of court in exchange for a promised bridge to the Island Airport and approximately $50 million.
