Submitting a complaint

Important information you should know

Publication of Review of Complaint reports

The Office of the Procurement Ombudsman (OPO)’s Review of Complaint reports will be posted on OPO’s website and will be referenced in the Procurement Ombudsman’s Annual Report. The name of the complainant will not be published, however the name of the federal organization will be identified in the report.

New Process

To improve efficiency and timeliness and ensure environmentally responsible operations, OPO will no longer send investigation reports by mail. All reports will be sent by email only.

Please note that we are required by Procurement Ombudsman Regulations to send a copy of your submitted complaint to the contracting department, regardless of whether we can review the complaint or not. Please visit the Frequently asked questions on how to make a complaint for more information or call us at 1-866-734-5169 to discuss your situation beforehand.
