My understanding is that we obviously keep under surveillance the facilities that are licensed under CNSC. CNSC also maintains fairly strict protocols with respect to any overflights or any potential risks to the security of the facilities.
In the spring of 2021, CNSC was advised of a request to fly a drone over a nuclear facility. That request was denied, and the requester complied. There are examples of the application of the protocol that it continues to be a matter of vigilance for the CNSC.
