In Canada, there are rules surrounding the ownership and operation of UAVs. Rightly so, as improper use can be dangerous and can put lives at risk. Transport Canada regulations state:
If the drone weighs more than 25 kg, you need a Special Flight Operations Certificate.
If the drone weighs between 250 grams and 25 kg, and is used for recreational purposes only, you'll need to obtain a drone pilot certificate before you can even operate the drone.
If the drone weighs less than 250 grams and is used for recreational purposes only, you don’t need Transport Canada’s permission, but you do need to follow the law, and learn to fly your drone safely.
