How to File a PIPEDA Complaint with the OPC

Step-by-step guide to filing a privacy complaint with the Office of the Privacy Commissioner of Canada.

TL;DR

The OPC expects the issue to be raised with the organization first and may not accept a complaint otherwise. A complaint to the OPC has no fixed deadline, but the Commissioner may decline one not filed within a reasonable period. The OPC investigates and issues a report of findings, and an application to the Federal Court is available within one year of the report.

Step 1: raise the issue with the organization

The OPC asks that the issue be raised with the organization first (PIPEDA s.12(1)(a) lets the Commissioner decline a complaint where the organization's own process was not used). A written complaint to the organization's privacy officer, with copies kept, is the usual starting point.

Step 2: file with the OPC

If the organization does not resolve the issue, a complaint can be filed online at priv.gc.ca or by mail.

The complaint should include: the name of the organization, what happened, when it happened, what you have already done to address it, and what outcome you want.

PIPEDA sets no fixed filing deadline, but the Commissioner may decline a complaint not filed within a reasonable period (s.12(1)(c)).

Step 3: OPC investigation and report

The OPC will acknowledge receipt, assign an investigator, and typically contact the organization for a response.

The OPC may attempt mediation or early resolution.

If the matter is not resolved, the OPC will issue a Report of Findings that states whether the complaint is well-founded, and may include recommendations.

Step 4: Federal Court

If the OPC's report does not resolve the matter, or the organization refuses to implement the recommendations, an application to the Federal Court can be made within one year of the report (s.14). The Federal Court has the power to award damages and order corrective measures (s.16).
