What should I do if an organization asks for my SIN and it is not legally required?
If you believe your Social Insurance Number (SIN) isn’t required, ask why it is being requested, how it will be used, and with whom it will be shared.
If your SIN is not required by law, explain that you prefer not to provide it. Offer different proof of identity.
If the organization refuses to provide the product or service unless you provide your SIN, ask to speak to the person in charge. Many organizations don’t know about the appropriate uses of the SIN. Once they understand, they may willingly change their practices.
If you are not satisfied with the organization’s response, you may formally complain to the Privacy Commissioner of Canada at www.privcom.gc.ca or 1 800 282-1376. There is no fee for making a complaint to the Privacy Commissioner.
You can also contact the organization’s industry association, ombudsman or complaint office. For example, the Canadian Marketing Association and the Canadian Banking Ombudsman handle customer complaints about their member companies.
