Complaints to the Chief of CSE

Making a Complaint

The Communications Security Establishment (CSE) Act makes provisions for individuals to submit complaints to the Chief of the CSE about any activities undertaken by CSE. The first step in making a complaint should be for individuals to gather as much information and documentation about the nature and circumstances of the complaint.

The written complaint should be forwarded to the Chief of the CSE at:

Communications Security Establishment
P.O. Box 9703,
Ottawa, ON
K1G 3Z4

CSE is committed to providing a response to a written complaint in a timely fashion, usually within 30 days. Should a response take longer than 30 days, the individual who submitted the complaint will be notified of the delay in writing and provided with an estimated timeline for completion.

In order to submit a complaint to CSE, we require certain personal information from you. Before you use our complaint form, please review the following privacy statement:
