​​​Effective Regulation, Proactive Engagement, Sustainable Solutions

CPAB is Canada’s audit regulator, protecting the investing public’s interests. As a world-class audit regulator, focused on excellence, we deliver value to our various stakeholders through effective regulation and by promoting high-quality, independent auditing. As a champion of audit quality, CPAB contributes to public confidence in the integrity of financial reporting, which supports our capital markets.

We fulfil our mandate in two ways: through inspections  and by involving a broader range of stakeholders  in a discussion about and better understanding of the audit process. This requires a multi-faceted approach to stakeholder engagement and inspection methodology, including root-cause analysis, risk assessment and value-added recommendations.

CPAB’s governing document, the Canadian Securities Administrators’ National Instrument - 52-108 Auditor Oversight​ requires auditors of reporting issuers to be registered with CPAB as CPAB participants, and requires Canadian reporting issuers to issue financial statements audited only by CPAB participating firms.

At December 31, 2018, 273 audit firms were registered with CPAB. During 2018, CPAB inspected 32 firms in total (2017:45) and 139 engagement files (2017:154).


CPAB has a nine member Board of Directors appointed by the Council of Governors.

Our Priorities

The Canadian Public Accountability Board (CPAB) contributes to audit quality in Canada, and is driven by a culture of integrity, commitment and collaboration.

The future audit environment will require an agile and progressive regulator keenly focused on improving audit quality and investor protection. Through 2019-21, CPAB will strengthen our regulatory effectiveness and drive higher quality audits by committing to:

Strategic Commitment ONE
Cultivate a proactive, adaptive and innovative culture that elevates our regulatory effectiveness.

Strategic Commitment TWO
Drive targeted, systemic changes to accelerate audit quality improvements.

Strategic Commitment THREE
Impact how the future audit is performed and regulated.

Strategic Commitment FOUR
Influence global audit quality consistency.

CPAB’s inspection methodology is risk based. We primarily assess the quality of audits through the inspection of selected high-risk sections of audit files and an assessment of the six elements of quality control. We then work with audit firms to develop solutions in areas where audit quality should be improved.

Stakeholder Engagement

Audit firms and financial statement preparers are not the only players in the audit process. Audit committees, institutional investors and analysts also play important roles. CPAB believes there is an opportunity to enhance audit quality and investor protection by engaging in a dialogue and raising awareness about audit quality among stakeholders.
