In accordance with Paragraphs AU-4.3.7A and BR-2.2.11, licensees must promptly notify the CBB in writing when a person undertaking a controlled function will no longer be carrying out that function. If a controlled function falls vacant, the licensee must appoint a permanent replacement (after obtaining CBB approval), within 120 calendar days of the vacancy occurring. Pending the appointment of a permanent replacement, the licensee must make immediate interim arrangements to ensure continuity of the duties and responsibilities of the controlled function affected, provided that such arrangements do not pose a conflict of duties. These interim arrangements must be approved by the CBB.
