On behalf of port users, the Board expressed complaints in the operation of the provincial commission, which made no improvements in the harbour.

The original 1817 plan intended to build a public walk and garden along the waterfront, just south of Front Street.

[4] The problem of silting, and the increasing amount of sewage being dumped in the harbour, required ongoing dredging efforts.

The existing port facilities were inadequate when a railway strike occurred in 1910, forcing vessels to wait days to dock.

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.

After the Gardiner Expressway was built, the Harbour Commission transferred the Sunnyside lands to the City of Toronto.

In the 1990s, the agency was requiring annual subsidies to manage the Island airport and the port lands.

Toronto's was added to the Port Authority program, largely at the insistence of local Liberal MP Dennis Mills.

The Authority and the City settled out of court in exchange for a promised bridge to the Island Airport and approximately $50 million.
