We would share information with the CBSA on a case-by-case basis, with a purpose, an intent, in mind. If we were aware that someone who is wanted may be returning from a foreign jurisdiction, we may inform CBSA. There may be instances where we are concerned about someone leaving Canada, but the CBSA has limited capacity to monitor exits from Canada. In fact, most often we would try to work with our international partners to identify the arrival in a foreign jurisdiction when somebody has departed Canada. There are no exit controls in Canada today, as we speak.
