In southern Canada, our volunteers use their own aircraft. For instance, I fly my own [Technical difficulty—Editor] search and rescue. I'm basically available to fly 24 hours a day, almost 365 days of the year. I have another job, but I have a lot of flexibility. When we go up north, where Dave is, or to Iqaluit—up in those areas—pretty much the only way for us to fly is to charter aircraft. We really don't have....
There are a couple of issues in the north. A lot of the private aircraft we use utilize aviation fuel called “100 low lead”. In the Arctic, a lot of the fuel is for turbine aircraft. They just have jet fuel in all of these different areas, so we can't even fly our airplanes up there. The only practical way is to charter aircraft or get the government to buy us aircraft that we can use up in the north. We're probably talking about a couple of million dollars per airplane, in order to get a plane with turbine capabilities that we can use up in the north.
Dave, do you want to comment on chartering?
