The Social Insurance Number Code of Practice
Annex 3 - SIN at risk: To do list for SIN holders

The security of your Social Insurance Number (SIN) can be put at risk by anyone, including yourself, or any organization that holds your SIN, whether it is by:

  • theft (for example, of your SIN card, documents containing your SIN, or computer/electronic records containing your SIN)
  • disclosure, either deliberate or accidental, to an untrustworthy individual or organization.

If your SIN has been put at risk, there are steps you should take to minimize any potential damage. These steps should be taken immediately when you become aware of the situation. The sooner you act, the more likely you'll be able to prevent personal loss or, at least, keep negative results to a minimum.
