On January 19, 2015, the Toronto Port Authority (TPA) rebranded as PortsToronto. Today, PortsToronto proudly owns and operates Billy Bishop Toronto City Airport, the Outer Harbour Marina, and Terminals 51 and 52 at the Port of Toronto. PortsToronto is a self-sustaining government business enterprise which invests in transportation infrastructure and community initiatives.

The Canada Marine Act originally established the TPA (now PortsToronto) on June 8, 1999, as part of a broad initiative of the federal government to modernize the administration and operation of ports. The TPA’s role was to operate the harbour and the airport. The TPA succeeded the Toronto Harbour Commissioners, which was founded in 1911.

The Toronto Harbour Commissioners was a joint federal-municipal agency responsible for the Toronto Harbour and the city’s waterfront. It was under the Harbour Commissioners that Billy Bishop Airport was constructed.
