Yes. My understanding is that under the terms of Bill C-59 it is the national security functions of CBSA that will be brought under the aegis of the new integrated review committee. It's not clear to me whether or not the more specifically customs-related activities of CBSA are covered under that. It's actually a bit unclear the extent to which all the activities of CBSA are covered, because the legislation specifies that it will be their national security activities that are subject to review by that committee.
