In April 2013, Porter announced expansion plans to serve new destinations in Western Canada, California and Florida. To support the expansion, Porter reached a provisional agreement to purchase 12 107-seat Bombardier CS100 jets, with a future option to purchase up to 18 more. Porter's plans required regulatory and facility changes to its Billy Bishop Toronto City Airport hub. Porter asked for modifications to the operating agreement of the airport to allow jets and extensions to the runway to support the new aircraft. Changes to the operating agreement require the unanimous agreement of the Toronto Port Authority (TPA), the City of Toronto and the Government of Canada. The TPA stated that it had no position on the expansion and would await a decision from Toronto City Council. Then-Toronto Mayor Rob Ford had indicated his support for the proposal while some councillors expressed their opposition with others urging further study.
