Do I have to give out my personal contact information when I file a complaint?

Yes. Section 20 of the Public Protector Act specifies that anyone who applies to have the Protecteur du citoyen intervene must provide:

• their name, address and phone number before stating the facts;
• any other information or document considered necessary for a clear understanding of the facts. 

As for reports, unless you want feedback from us, you do not have to provide any personal information.
