This was considered when the order was drafted. Section 3, “Duty to determine”, inserts into the order an obligation on the financial entities to “determine on a continuing basis whether they are in possession or control of property that is owned, held or controlled by or on behalf of a designated person”. That section was inserted specifically for the purpose of ensuring compliance with the charter and ensuring that financial institutions review this on an ongoing basis.
