Interesting discussion! Sorry I'm late to the party, but thank you zbip for inviting me! Firstly, yes Drone Pilot Canada shows the boundaries of both National and Provincial Parks, and a quick summary of their drone policies...which vary by province. The Fortress of Louisbourg is a National Historic Site, but neither a national nor provincial park. That said, there are a ZILLION places that have defined their own rules for activities ON their property, and this place may well have declared those. But other than National Parks, none of these places have any jurisdiction over their airspace, so yes you can fly OVER them. Note that the right to fly over them does NOT give you the right to harass people or wildlife, nor to infringe on privacy.
Drone Pilot Canada is updated regularly with new features, and the aerodrome/airspace data is refreshed every 56 days, following the CFS/DAH data updates. All features are documented in a simple user guide available on
www.DronePilotCanada.com, and there are tutorials showing everything from simply getting started to very detailed feature walkthroughs here:

And to our American friends, while the SFOC process is technically the way to get permission to fly a drone over 250g in Canada, at present, Transport Canada is not accepting applications for recreational flying....
