Do you mean in the administration of the program? The information sharing hasn't passed, of course, and my understanding is that it won't be shared until royal assent is given, and so the guidelines of the Privacy Commissioner in sharing information won't have come into effect because they haven't started yet. However, once the sharing of taxpayer information commences, then the office of the Privacy Commissioner would be working with the Canada Revenue Agency to ensure that the appropriate safeguards are not only in place but are followed.
