Canada has five tankers, and they're based in Trenton. I think that that's sufficient, but just barely sufficient, because oftentimes our tankers are required overseas. I guess that would be the short answer. If you have one tanker dedicated to the Syrian theatre, one in refit, another one dedicated to perhaps some other mission, and then one for North America, then you are cutting it awfully close. It's a big country. Canada is often required to call on U.S. tankers to refuel our fighter aircraft.
