Windsor International Airport (IATA: YQG, ICAO: CYQG) is located in the southeast portion of the city of Windsor, Ontario, Canada. The airport serves a mixture of scheduled airline flights and general aviation, and is a popular point of entry into Canada for private and business aircraft. The airspace above the airport is exceptionally busy because of the proximity to Detroit Metropolitan Wayne County Airport, and Instrument Flight Rules (IFR) arrivals and departures are handled by Detroit approach control.

The airport is classified as an airport of entry by Nav Canada and is staffed by the Canada Border Services Agency (CBSA). CBSA officers at this airport can handle aircraft up to 325 passengers, and can handle up to 450 if the aircraft is unloaded in stages.
