The office of the Public Interest Commissioner is an independent office of the Alberta Legislative Assembly, responsible for investigating allegations of wrongdoing in the public service and complaints of reprisal made under the Public Interest Disclosure (Whistleblower Protection) Act.



As one of Alberta’s Legislative Officers, the Public Interest Commissioner facilitates the disclosure and investigation of significant and serious matters in or relating to departments, public entities, offices or prescribed service providers, that an employee believes may be unlawful, dangerous to the public or injurious to the public interest.

The Commissioner investigates allegations of wrongdoing and investigates complaints where an employee believes a reprisal has occurred against them for reporting wrongdoing or seeking advice.

The Commissioner is responsible for conducting fair and impartial investigations, and making strong and effective recommendations for corrective measures when wrongdoing is found. The Commissioner’s office aims to promote a culture within the public sector that encourages employees and management to report wrongdoings in their workplace.

The Public Interest Commissioner is the resource for public sector employees who believe wrongdoing is occurring in their organization, and want to receive the confidentiality and protection provisions of the Public Interest Disclosure (Whistleblower Protection) Act.
