A Social Insurance Number (SIN) is a nine-digit number issued by the Government of Canada and used exclusively by you. You will need a SIN to work in Canada or to have access to government programs and benefits.
Visit a Service Canada office to get your SIN. You will need to take your passport and study permit with you. Your study permit must indicate that you are authorized to work according to the regulations in order to be issued a SIN. You should receive your SIN during your visit and you will not be required to part with your study permit. For more detailed information on how to apply, visit here.
Your SIN is confidential and you should protect it. We recommend that you store any document containing your SIN in a safe location and do not keep it in a wallet or on your person. Do not share your SIN unless it is required. See here for who can ask for your SIN and who cannot.
