When a provision begins with “for greater certainty”, it announces that the intention is not to modify anything in law or indicates that the act does not affect or does not.... It essentially states what is already the case. Usually these clauses are included for transparency and clarity so that someone reading the act doesn't misinterpret it. In this case, clause 6 is about use of information received by virtue of the act or further disclosure. We are saying here that for greater certainty this act does not address use or further disclosure of information. That use or further disclosure may be undertaken by the recipients, as they currently do, when they receive information in accordance with the law, meaning either their departmental mandates or limitations or prohibitions in the law, including under the Privacy Act, and in accordance with the charter.
