DO NOT SHOOT AT THE DRONE!!!!!! (as tempting/fun as it would be)
You would create so many new problems for yourself. Get as much detail as possible about it, where it came from, direction of flight etc. Report all to local police, also Transport Canada has online reporting tools. The base for it can't be that far away unless it's some sort of Gov't drone, which I doubt it was. If you're going to "shoot" at it... try a high pressure water stream. The potato gun idea is interesting. But have to watch velocities so you don't enter into criminal code territory.
Rules for recreational drones
To fly a recreational drone (or model aircraft), you must follow the safety rules in the Interim Order Respecting the Use of Model Aircraft.
Review these rules before flying a drone for fun, if the drone weighs over 250 g and under 35 kg. If your drone is 250 g or less, read our tips for flying safe.
Following the safety rules helps keep people, aircraft and property safe. If you fly where you are not allowed or you break the rules below, you could be fined up to $3,000.
Fly your drone:
below 90 m above the ground
at least 30 m away from vehicles, vessels and the public (if your drone weighs over 250 g and up to 1 kg)
at least 76 m away from vehicles, vessels and the public (if your drone weighs over 1 kg and up to 35 kg)
at least 5.6 km away from aerodromes (any airport, seaplane base or area where aircraft take off and land)
at least 1.9 km away from heliports or aerodromes used by helicopters only
outside of controlled or restricted airspace
at least 9 km away from a natural hazard or disaster area
away from areas where its use could interfere with police or first responders
during the day and not in clouds
within your sight at all times
within 500 m of yourself
only if clearly marked with your name, address and telephone number
You are exempt from these rules if you are at a field or event approved by the Model Aeronautics Association of Canada.
