Buttonville Municipal Airport or Toronto/Buttonville Municipal Airport, , is a medium-sized airport in Buttonville, Ontario, Canada, within Markham and 29 km north of downtown Toronto. It is operated by Toronto Airways Limited. Due to its proximity to Toronto's suburbs, there are several strict noise-reduction procedures for aircraft using the airport. There is a weather station located at the airport. The airport is open and staffed 24 hours a day, 365 days a year. In 2007, Buttonville was Canada's 8th busiest airport by aircraft movements.
The airport is classified as an airport of entry by NAV CANADA and is staffed by the Canada Border Services Agency. CBSA officers at this airport currently can handle general aviation aircraft only, with no more than 15 passengers.
Buttonville Airport began as a grass airstrip in 1953 when Leggat Aviation moved their operations from Barker Field in Toronto. The airstrip became an official airport in 1962.
Flightline is available on 123.50 MHz.
There are three ground-based navigation aids attached specifically to the Buttonville airport:
It has been agreed with the Airport and the Town of Markham that no circuit practice will occur during specific hours during a long weekend holiday.
On January 17, 2006, NAV CANADA announced plans for the construction of a new air traffic control tower at Buttonville Airport.
The new tower, representing an investment of over $2 million, will replace the existing facility which was built in 1967 and is reaching the end of its useful life. Construction began in Fall 2006 and became fully operational on June 26, 2007.
The new tower provides expanded operational space, optimal visibility and the latest in air navigation equipment and technology for 12 air traffic controllers and two support staff who provide service to some 150,000 aircraft movements per year at Buttonville Airport. It is located on the south side of the airport – the opposite side of the old tower.
The new tower was designed and built using a modular design enabling the facility to be relocated in the future. New equipment and technology include the NAV CANADA Auxiliary Radar Display System and the Company’s state-of-the-art voice communications switch. Buttonville Airport is one of the busiest in the country, consistently ranking in the top 11 for air traffic volumes.
However, Buttonville Airport is still privately owned and Transport Canada has not yet made a decision on a Pickering airport project.
