The Toronto Port Authority (TPA) was renamed PortsToronto on January 19, 2015. The TPA succeeded the Toronto Harbour Commissioners, which was founded in 1911. PortsToronto is a self-sustaining organization that does not receive public funding from any level of government. PortsToronto is accountable to the Federal Government through Transport Canada, and is guided by a nine-member Board of Directors composed of individuals appointed by all levels of government – Municipal, Provincial and Federal. The Tripartite Agreement is a contract that governs the management and operation of the Billy Bishop Airport and has three signatories: Her Majesty in Right of Canada as represented by the Minister of Transport, the City of Toronto and PortsToronto. The Tripartite Agreement recognizes that PortsToronto operates a public airport facility but on predominantly private lands owned by PortsToronto. All buildings and structures at the airport are situated on PortsToronto lands. Since 2009 PortsToronto has invested more than $8 million in community and environmental initiatives under the pillars of sports and recreation, arts and culture, protection of the environment and education. In 2013, PortsToronto reinvested more than $42 million in waterfront infrastructure, ranging from the replacement of equipment to the maintenance and restoration of our various facilities along the waterfront. PortsToronto is committed to leading and investing in projects that help protect the environment. For example, PortsToronto and Toronto and Region Conservation Authority recently completed the creation of a wetland area and fish habitat in Tommy Thompson Park on the Leslie Street Spit. PortsToronto and Billy Bishop Airport are the only port authority and airport in Canada, respectively, that choose renewable energy for all operations. PortsToronto is one of the top users of Bullfrog Power in the nation. PortsToronto is committed to community engagement through a number of initiatives, including a Committee Liaison Committee, PortsToronto's annual Sail-In Cinema movie festival, and the Tunnel Construction Committee.
