With respect to SMS—safety management systems—right now, obviously, operators can apply them on a voluntary basis, and we support that very much, but they apply to air carriers of 20 passengers and above, which we classify as the 705 carriers. The next step for us, which we're assessing right now, is whether or not to introduce a regulatory requirement for SMS in the smaller carriers, the 10- to 20-passenger operations, and the 0- to 10-passenger operations, the air taxi operations.
What we're trying to assess first is industry's capacity to implement those types of systems. Obviously, a smaller company doesn't have the same resource base that an Air Canada might have to implement the system. We're also assessing what our resource requirements are or would be to oversee an introduction of those regulatory changes, should they be brought about.
