I stumbled onto this from a government site being new to drones and trying to put my most responsible foot forward.
I have been using this site to find the gaps between nfz's specifically due to airports and landing pads in southern ontario (the public, ontario parks, vehicle/vessel avoidance aside).
IT's great on my desktop pc but on my phone the menu overlay blocks out the map rendering it useless.

What other resources can i use? suggestions?
(preferably mobile friendly- phone, not tablet..)

Thanks for sharing this info ..

I should have noted- the menu that's annoyingly over the map does allow for above/below 1kg uav (drone). Phantom vs Mavic users in Ontario have different allowances re proximity to helipads now..
