The Billy Bishop Toronto City Airport (IATA: YTZ, ICAO: CYTZ), commonly known as the Toronto Island Airport and previously known officially as Toronto City Centre Airport, is a small airport located on the Toronto Islands in Toronto, Ontario, Canada. It is used for civil aviation, medical flights, and regional airlines using turboprop planes.
Since 2000, the airport has been a centre of controversy between community groups and Toronto politicians wishing to close the airport and the airport's operator, the PortsToronto and its primary tenant, Porter Airlines, who want to expand its usage.
As of 2010 it was Canada's 14th busiest airport and Ontario's 3rd busiest airport by passengers with 1,130,625 and the 17th busiest Canadian airport in terms of aircraft movements with 113,685. With a 46% increase in passenger traffic from 2009 into 2010, it is also one of the fastest growing airports in Canada.
