Mr. Speaker, “Open and Accountable Government” sets out the Prime Minister’s expectations for his ministry. The Prime Minister may determine whether a particular minister is meeting those expectations and whether any corrective action should be taken. Similarly, it is the responsibility of each minister to ensure that the exempt staff in his or her office are acting in accordance with guidelines applicable to those staff. Privy Council Office, PCO, officials may support the Prime Minister in providing advice on how such guidance can be interpreted or applied and how it relates to other documents or legal instruments, such as the Conflict of Interest Act and the Lobbying Act. PCO officials further support the Prime Minister with respect to Governor-in-Council appointment processes for senior government officials.
