Your question was about which is more dangerous, the large or the small.
A loonie being ingested into an engine can cause severe damage.There is drone technology involving clusters. They're really small and they fly in formation. Even the smallest drones can cause some damage.
To me, they're all the same risk. They have to be flown with the proper education, with the knowledge of the risk they could potentially pose if they're doing something they're not supposed to. They especially have to stay out of the national airspace.
We encourage flying for recreational purposes. I agree with that, but you cannot fly over built-up areas or over crowds or over sporting events. Those are all guidelines currently on the Transport Canada website saying you should not do that. We have to look at all of this.
