We regularly monitor all planes, trucks, and other vehicles coming into the country. We work with the other intelligence services in Canada to do further research, when we suspect that planes that are about to arrive in the country might be targeted by the sanctions. This is something that falls under the purview of Transport Canada, but we support the department in its efforts by conducting a more thorough check. When we have suspicions, we advise them that they need to investigate the incident in question.
