Minimum Altitudes and Distances
Except where conducting a takeoff, approach or landing or where permitted under CARS Section 602.15, no person shall operate an aircraft
(a) over a built-up area or over an open-air assembly of persons unless the aircraft is operated at an altitude from which, in the event of an emergency necessitating an immediate landing, it would be possible to land the aircraft without creating a hazard to persons or property on the surface, and, in any case, at an altitude that is not lower than
(i) for aeroplanes, 1,000 feet above the highest obstacle located within a horizontal distance of 2,000 feet from the aeroplane,
(ii) for balloons, 500 feet above the highest obstacle located within a horizontal distance of 500 feet from the balloon, or
(iii) for an aircraft other than an aeroplane or a balloon, 1,000 feet above the highest obstacle located within a horizontal distance of 500 feet from the aircraft; and
(b) in circumstances other than those referred to in paragraph (a), at a distance less than 500 feet from any person, vessel, vehicle or structure.
Minimum Altitudes — Overflying Aerodromes602.96
Unless otherwise authorized by the appropriate air traffic control unit, no pilot-in-command shall operate an aircraft at a height of less than 2 000 feet over an aerodrome except for the purpose of landing or taking off.
Fur and Poultry Farms
Experience has shown that aviation noise caused by rotary wing and fixed wing aircraft flying at low altitudes can cause serious economic losses to the farming industry. The classes of livestock particularly sensitive are poultry (including ostriches and emus), because of the crowding syndrome and stampeding behaviour they exhibit when irritated and frightened, and foxes who, when excited, will eat or abandon their young. Avoid overflying these farms below 2 000 feet AGL. Fur farms may be marked with chrome yellow and black strips painted on pylons or roofs. In addition, a red flag may be flown during whelping season (February – May). While poultry are less sensitive, they exhibit similar characteristics.
