Internal Audit Charter

Revised: May 2012


Federal government agencies, including Agents of Parliament, are expected to have an Internal Audit Charter for their internal audit functions. The Charter describes the purpose, authority and responsibilities of the internal audit function and the scope and nature of the services it provides. The Charter also establishes Internal Audit’s position in the organization describes reporting relationships and authorizes access to records and personnel relevant to the performance of audit engagements.

The spirit and intent of the Treasury Board Policy on Internal AuditFootnote 1 is respected in this Charter, taking into consideration the Joint Agreement of the Working Group of Agents of ParliamentFootnote 2. The Working Group of Agents of Parliament agreed that the intent of the government’s Internal Audit Policy shall be reflected in the Internal Audit systems, processes and infrastructure within each Office of Parliament, but with consideration for their status of independence, their relatively small size and the oversight role played by the Parliamentary Advisory Panel on the funding of Agents of Parliament.

This document is considered as ‘evergreen’ in that it will evolve over time as lessons are learned about application in general of the government’s Internal Audit Policy and in specific terms to the special circumstances of the Commissioner as an Officer of ParliamentFootnote 3.


Internal auditing in the Government of Canada is a professional, independent and objective appraisal function that uses a disciplined, evidence-based approach to assess and improve the effectiveness of risk management, control and governance processes.

For the internal audit profession, the above-described role is referred to as providing assurance.  It is intended to assist decision-makers to exercise oversight and control over their organizations and apply sound risk management.

Internal audit adds value by assessing and contributing to the improvement of risk management, control, and governance processes. In doing so, it helps ensure that the organization achieves its objectives efficiently and in a way that demonstrates informed ethical and accountable decision-making.

Principally as an adjunct to the assurance role, and within their sphere of expertise, internal auditors may also provide consulting services to their organization.


The internal audit function will be guided by the Government of Canada’s Policy on Internal Audit, Directive on Internal Auditing in the Government of Canada and the Internal Auditing Standards for the Government of Canada.

A risk-based audit plan will be prepared on an annual basis that is consistent with OPC objectives, considers input from OPC senior management, and supports the provision of assurance services on the effectiveness and adequacy of risk management, control, and governance processes. As well, consideration will be given to the horizontal or sectoral audit themes from Office of the Comptroller General audits.

The risk-based audit plan is to be reviewed and recommended for approval by the Audit Committee (the Committee) and approved by the Commissioner. The Advisory Panel on the Funding of Agents of Parliament and other parliamentary committees will be informed of the audit plan and audit reports, as appropriate.

Internal audit engagements will be contracted out to audit professionals following government contracting guidelines. The next section explains how the OPC ensures the integrity of the internal audit function.

The Internal Audit (IA) function focuses primarily on the provision of assurance services. Other services are provided only as an exception.


The Internal Audit function needs to be independent to allow internal auditors to make assessments impartially and without bias, while avoiding conflicts of interest. Given its small organizational size, it is not practical for the OPC to dedicate a full-time resource to internal audit. In this context, the Director General, Corporate Services of OPC is the Chief Audit Executive (CAE) while also being the Chief Financial Officer (CFO). In line with the TBS IA Policy, the incumbent is a senior executive who reports directly to the Officer of Parliament and has an accounting designation.

The integrity of the internal audit function is assured through the following mechanisms:

  • Contracted audit professionals are engaged to develop the OPC risk-based internal annual audit plan and to audit the OPC programs and management processes and practices. Audit products from the contracted resources are to be labelled under the auditors’ letter head to show their independence. Auditors are provided with access to all OPC records, databases, workplaces and employees, and the right to obtain information and explanations from OPC employees and contractors;
  • The Committee reviews and recommends for approval the risk-based internal audit plan, and the Commissioner approves the plan ; and
  • A direct reporting line is established between the contracted audit professionals and both the Commissioner and the Committee. This way, the auditors present their audit findings directly to the Commissioner and Committee and are not required to first go through the CAE when audit findings relate to corporate services and all other areas for which this position has responsibility.

The CAE remains responsible and accountable to ensure the integrity of the Internal Audit function.

To preserve its independence and ensure it remains solely accountable for its internal audit function, the OPC will not provide the Comptroller General with access to internal audit staff and working papers as normally required under the Policy.  As well, the OPC will not normally participate in government-wide audits initiated by the Comptroller General.


Internal Audit Reports

Upon approval of the Commissioner, internal audit reports will be posted on the OPC website in both official languages in a timely fashion to the extent possible by the Access to Information Act and the Privacy Act.

The Senior Management Committee (SMC) will receive copies of the audit reports once they have been approved by the Commissioner.

Annual Internal Audit Report of the Chief Audit Executive

The CAE shall prepare a written report annually to the Commissioner and the Committee that will include sections on:

  • Internal audit’s independence, proficiency, performance and results relative to its plan including resource utilization, lessons learned and influences on future years’ plans;
