Thank you very much, and thanks to our witnesses for being here, including remotely.
Quickly, for Nav Canada, I'm interested in your view on the transponders. Should we only be dealing with certain UAVs that should have this kind of transponder, for example, the ones in controlled areas or ones above a certain weight class? The fear I have is that we will be over-regulating, if we're applying it to, essentially, what most people view as toys.
