I agree with Bernard. Right now, no, the technology is not there.
There is a lot of stuff. We haven't talked about geofencing for UASs that are equipped with GPS. You could program them so that if they go to within, say, nine kilometres of an airport, they're just going to stop and hover; they're not going to go any further. You could build that geofencing around the Parliament Buildings; it's the same sort of thing. You could build it so that there's a maximum height.
That technology is there, but it's not being used everywhere.
