RE: Recommend No.2 PARK flyers concern
I did some checking around on the municipal by-laws for my area (north of TO).
Most ban any form of radio-control in town parks. Newmarket is specifically phrased "no control-line or radio-control airplanes", Concord/Vaughn seems to be the same way (search "Dufferin Reservoir" on RC Canada), and Aurora has nothing specific on the books but requires permits (and proof of insurance) for any use of their parks besides using the playground and walking your dog or yourself.
It really does come down to insurance and covering the risks. MAAC is trying its best to educate its members on how to handle the situation and to be proactive. Towns and cities are making sure that they don't get sued because someone injures someone else with an airplane in one of their parks.
We are always going to have people who don't give a darn or are ignorant (without knowledge, not uncouth).
