A social insurance number (SIN) is really useful. You need your SIN to get a job, tax refunds, and student loans.
Do I already have a SIN card?
If you had a Continuing Custody Order (CCO) or were a permanent ward you may have a SIN card. Contact the Public Guardian and Trustee’s office to find out.
