As mentioned before, our remotely piloted aircraft enhances our ability to do Arctic surveillance. They're equipped with all of the cameras and monitoring technology that currently exist on Dash 7s, but what they also enable us to do is live data streaming and a better mapping capability than otherwise.
With respect to the security of drones, this has been a focus of the department for a number of years through our regulatory initiatives. Transport Canada—and Canada—has been a leader in terms of the regulation and safety and security of drone technology to ensure that they are free from nefarious uses and interception. The technology and how they're used is regulated and governed by what we do at Transport Canada.
