Billy Bishop Airport allows business travellers, downtown residents to take a short trip to the airport from Mississauga Pearson Airport. In 1999, the new Toronto Port Authority (TPA) (renamed PortsToronto) replaced THC. TPA`s mandate was to make the port and airport self-sufficient, and it found that the airport needed to be expanded to end the annual subsidy. Although the airport expansion has been and remains politically controversial, TPA has been cooperating since 2003 with the new regional airline Porter Airlines to increase scheduled flights. Under the new financial model, airlines pay landing fees and airport passengers at the airport to increase destination fees at the TPA. Porter started in 2006 and the number of passengers increased so much that the airport`s operation became self-sufficient until 2010. In 2010, Porter opened a new terminal. A pedestrian tunnel leading to the airport was opened in 2015 following the removal of a previous bridge construction plan.  Ships of the Toronto Police Service Marine Unit and Toronto Fire Services (William Lyon Mackenzie and Sora) can conduct rescue operations in waters near the airport. Opposition to the airport was formalized in 2001 in the Air Air Voluntary Association (Airport Impact Review) under the leadership of activist and former City Councillor Allan Sparrow. It was created by local residents to oppose the expansion due to increased air and noise pollution, safety concerns and increased air traffic, which will hamper recent government initiatives to rejuvenate Toronto`s waterfront.  In July 2001, at a press conference with representatives of the Sierra Club, the David Suzuki Foundation and the Toronto Environmental Alliance, the group proposed to transform the 81-hectare airport into parkland.  Community Air has been and is supported by local councillors.
The Staff report was released on November 28, 2013 and staff recommended that the review of the plan be deferred to 2015 due to incomplete information and various unresolved issues, including CS100 noise information, Canadian transportation regulations and Toronto Port Authority requirements.
