King City Airport

The airport, which served as the flight training campus for Seneca College's aviation program, was closed when the college consolidated its operations and relocated the program to a new, modern facility at Peterborough Airport (CYPQ). This was a strategic and economic decision by the college to modernize and centralize its aviation education.

The airport is permanently closed. The runway, though still faintly visible in satellite imagery, is marked with large white 'X's, indicating it is unusable for aircraft. The surrounding land, part of the historic Eaton Hall estate, was sold by Seneca College in 2018 and is now owned by a development corporation. The site is undergoing a redevelopment process, with plans focused on conservation, heritage preservation, and potential institutional or residential uses.

The airport's primary historical significance is as the former home of the Seneca College School of Aviation, one of Canada's largest and most respected flight training institutions. From the late 1960s until its closure in 2014, it was a bustling training airfield where thousands of commercial pilots received their initial training on a fleet of single-engine trainers (like Cessna 172s) and multi-engine trainers (like the Beechcraft Duchess and Baron). The airfield was located on the historic Eaton Hall estate, originally built by the Eaton family (of the former Eaton's department store chain). It was a vital hub for Canadian aviation education for over four decades.

There are no plans or prospects for reopening the airport. The sale of the land for non-aviation redevelopment and its location within a growing community make its return to service as an airfield virtually impossible. The focus of the new landowners is on land development, not aviation.
