What to do if your SIN is Lost or Stolen
Your social insurance number (SIN) is super important in regards to your identity. It is used to identify yourself to the federal government, receive pay from employment, apply and receive credit lines as well as many other things. You have to be careful who you give the number to and where you keep it because it can easily be used to steal your identity. So what happens when you can’t find this card? Well, whether it is lost or stolen, you want to prevent someone from using it to identify where it has been used as soon as possible.
