Yes. The Royal Canadian Navy is responsible for the security of this traffic, both in Canadian and adjoining waters. Our mandate has more to do with the safety of this traffic. We have to ensure that navigation is safe, that there are aids to navigation, that there is a traffic management system, and that there are resources that can respond in case of emergency, as well as to provide icebreaking services.
