In terms of the maintenance of an aircraft and the situation—and that is a hypothetical situation, so I'm providing an answer in a hypothetical state—for the in-service support that's been procured under a foreign military sale, this sale comprises an exception to the ITAR requirement, and a Department of State licence is not required for sharing ITAR-controlled technology material among the employees of the purchasing government.
So those Canadian Forces technicians who would have to go to Cuba to maintain that airplane, in order to bring it back home, would not be subject to ITAR requirements.
