- A licence needed to fly near an airport at night
- A list of registered drones in a given region
Near a forest fire, which airspace is closed to all aircraft, drones included?
- Below 3,000 ft AGL within 5 NM of the fire area
- Below 400 ft AGL within 3 NM of the fire area
- Only the airspace directly above the flames
- Below 1,000 ft AGL within 1 NM of the fire area
Your site lies inside a CYA area used for hang gliding. What applies?
- You must get written permission from NAV CANADA before flight
- You may not fly at all without an SFOC from Transport Canada
- You must equip your drone with a transponder before flight
- You may fly, but should plan for the extra low-level traffic
For drone operations, which classes count as controlled airspace?
- Only Class F restricted areas
- Classes C, D, F and G
- Classes A, B, C, D and E
- Classes A, B and C only

Canadian Domestic Airspace (CDA)
- Covers the Canadian land mass, the Arctic and Arctic Archipelago, and high seas inside the boundaries.
- Seven classes: A, B, C, D, E, F, G. Limits are published in the Designated Airspace Handbook (DAH).
- A drone must stay inside CDA (CAR 901.13) unless flown under an SFOC—RPAS.
Controlled airspace
- For drones, controlled airspace = Classes A, B, C, D and E. Class F can be controlled, uncontrolled or both.
- Basic pilots must stay out of controlled airspace. Entry needs all three: advanced certificate, a drone with the right safety declaration (Standard 922.04), and an authorization from the air navigation service provider (ANSP; NAV CANADA, or DND for military airspace).
- Class A: high level, from FL180 in Southern Domestic Airspace; not shown on charts. Class B: 12,500 ft ASL up to Class A (some lower zones). Both need TC (SFOC) and ANSP permission.
- Class C: around large airports, usually surface to 3,000 ft AGL; becomes Class E when the tower is closed.
- Class D: around medium airports, usually surface to 3,000 ft AGL; becomes Class E when the tower is closed.
- Class E: controlled for IFR traffic; control zones usually surface to 3,000 ft AGL; away from airports usually from 700 ft AGL (or 2,200 ft AGL in extensions) up to 12,500 ft ASL.
- Class G: everything that is not A–F; uncontrolled; the basic operating environment.
Class F special use airspace
- Restricted: shown as CYR + three digits (e.g. CYR123), e.g. over prisons or military ranges. All aircraft, including microdrones, must stay out unless the user agency in the DAH approves. Over international waters the letter D (danger area) is used.
- Advisory: CYA + three digits (hang gliding, flight training, helicopter work). Drones may fly there without permission but should identify and reduce the added risk; traffic often operates below 400 ft AGL.
- DAH is updated every 56 days.
Other airspace restrictions
- CAR 601.15 forest fires: no aircraft below 3,000 ft AGL within 5 NM (9.3 km) of a forest fire area, or as described in a NOTAM.
- Aeronautics Act s. 5.1: the Minister can restrict any airspace by NOTAM (e.g. disaster areas). Applies to all aircraft, drones included.
- RPA restricted airspace created by NOTAM moves to the DAH if it lasts more than 90 days and appears in NAV Drone.
Drone Site Selection Tool (NRC)
- Choose basic or advanced first. Red = prohibited; yellow = extra caution (other air traffic); orange = permission needed (NAV CANADA, Parks Canada, DND or airport operator).
- NAV CANADA's NAV Drone shows airspace and is used by advanced pilots to request flight authorizations in NAV CANADA airspace.
Inadvertent entry
- If the drone is no longer under control and enters or is likely to enter controlled airspace or Class F restricted airspace, notify the ATC unit, flight service station or user agency immediately.
- Keep the ANSP / user agency contact information at hand when flying near such airspace (fly-away planning). Fine for failing to notify: $3,000 individual / $15,000 corporation.
Transponder airspace
- Transponders required in all Class A, B and C airspace and some D and E (listed in the DAH).
- A drone without a transponder may enter only if ATC authorizes it before entry and safety is not likely to be affected (CAR 901.46).
NOTAM
- NOTAM: notice of temporary or short-notice changes to facilities, services, procedures or hazards (includes time, location and details).
- Check NOTAMs in the NAV CANADA portal or NAV Drone during the site survey. A NOTAM for a normal drone flight is not normally required; TC with NAV CANADA decides when one is needed.
