In Canada, as of now, we don't have to place any identity markings on our recreational drones, nor do we have to register them. However, if one of mine lands in the woods or in some location where I can't retrieve it, I'd like someone to call me should it be found.... I think that's a good idea, or I could be wrong. For this reason I place a contact phone number on all of my drones (I've blocked out part of the number in the attached photo). Does anyone else do something similar if not mandated to do so?
