Thank you, Admiral.
I really was talking about the challenges associated with the civil infrastructure that exists in the north. With respect to search and rescue activities, I am going to focus on ground operations.
As a means of communication, many people in the north are equipped with satellite communication terminals, such as Garmin or GPS devices. The biggest problem that arises in search and rescue is definitely associated with communication. When people don't report in on time and we have trouble communicating with them to find out whether they are safe and sound, we then have to initiate search operations. Ground searches are conducted first by people in the territory or community. If local resources are insufficient, they can ask me to call in the Canadian Rangers to augment the ground search capacities and find the missing people.
So I would say that what presents the biggest problem in that regard is usually communication difficulties.
