Oshawa Executive Airport is a municipal airport adjacent to the north end of the city of Oshawa, Ontario, Canada. It is the busiest general aviation airport without scheduled airline service in the Greater Toronto Area by aircraft movements and one of the busiest general aviation only airports in Canada. It includes two paved runways and instrument approaches. From 2002 to 2008, Oshawa hosted the annual Canadian Aviation Expo, Canada's largest annual aviation event, before the expo moved to John C. Munro Hamilton International Airport in 2009. Oshawa Airport now hosts the Girls Take Flight event that takes place every spring. The airport is classified as an airport of entry by Nav Canada and is staffed on call by the Canada Border Services Agency. CBSA officers at this airport can handle aircraft with no more than 50 passengers. The officers also provide weekday call out for general aviation arriving from outside Canada to Buttonville Municipal Airport in Markham, Ontario. History The airport opened in June 1941 under the British Commonwealth Air Training Plan as No. 20 Elementary Flying Training School RCAF Station Oshawa. Student flyers used Tiger Moth aircraft and were trained by civilian instructors from the Oshawa, Kingston, and Brant-Norfolk flying clubs. A relief landing field was located at Whitby. The school closed in December 1944 and the airfield was turned over to the Department of Transport. The then-Town of Oshawa took over the facility in 1947. The planned construction of a Pickering Airport, between Oshawa and Toronto, raised questions about the future of the Oshawa airport. In 2018 the mayor of nearby Pickering made the construction of a new modern jet airport in Pickering a key part of his platform, winning a landslide victory. Local media continues to report that there remains strong opposition to the construction of the Pickering Airport by some residents. This project was initiated in 1972, then placed on hold in 1975. The Greater Toronto Airports Authority (GTAA) is not related to Oshawa Airport in any way and as of 2011 has no further role in Pickering Airports development. In 2008 the City of Oshawa adopted the Oshawa Municipal Airport Business Plan which includes a commitment to operate the airport for a minimum of 25 years. Dozens of upgrades completed by 2010 include construction of new Taxiway "C", Phase 1 of Hangarminium Complex, cardlock fuel facility, and Automated Weather Observation System. On July 11, 2011,
