It sits under the eastern reaches of Toronto Centre's airspace and provides customs clearance facilities for visiting aircraft.
Barrie-Lake Simcoe Regional Airport, identified by the ICAO code CYLS and IATA code YLK, is a medium-sized aerodrome serving the city of Barrie, Ontario. It offers a pilot flying into the Lake Simcoe region a well-equipped field with two lit, hard-surfaced runways and customs clearance available for cross-border arrivals, making it a practical destination for both training flights and cross-country touring in the simulator.
The airport lies near Oro Station, north-east of the city of Barrie, Ontario, at an elevation of 961 feet. Air traffic in the area is worked by Toronto Centre, reachable on 124.025 MHz, placing the field within the broader Toronto terminal environment while remaining an uncontrolled aerodrome operating under an Aerodrome Traffic Frequency. The nearest other airfield listed is at Coulson, Ontario, roughly 7 km to the north-west.
CYLS has one physical runway pair, 10/28, both hard-surfaced and lit. Runway 10 is 5,985 feet long and Runway 28 is 5,682 feet long, giving ample length for a wide variety of aircraft types. There is no ILS approach available at the field.
Pilots should monitor the Automated Weather Observation System on 122.975 MHz for current conditions. The aerodrome operates on an ATF/UNICOM frequency of 122.7 MHz for local traffic advisories, while Toronto Centre can be contacted on 124.025 MHz for the surrounding controlled airspace.
