We have had discussions with our U.S. counterparts. Initially they were running these drones on their southern border. Then when they began to implement them on the northern border—our southern border—they were implementing them on their side. We've had discussions over how to improve border security, over technology, over how to work together to complement each other, as opposed to duplicating our efforts. They're working right now on the secure border initiative. We have one person seconded to them to ensure that all technology that's brought in, such as drones, for example, is done in a way that we can work together to complement each other.
Any time a vehicle such as a drone enters Canadian airspace, we're notified before that happens.
