Use and protect the SIN after being issued

Once your SIN is issued, Service Canada will store your personal information in the Social Insurance Registry.

When to use SIN numbers?

You will have to provide a SIN:

  • After being recruited
  • For personal income tax return purposes
  • When opening an account from which you earn interest at a financial institution such as a bank, or credit union
  • Access to government programs and benefits including: Canada Pension Plan (CPP), Unemployment Insurance benefits, Canadian Child Benefit, Child support, Loan programs for Canadian students, GST/HST, value-added tax refund.

Some businesses may require you to provide a SIN number. This is extremely restrictive, not advisable, but not illegal.

Examples of situations where you don’t have to provide your SIN:

  • Prove your identity (except for some government programs)
  • Applying for a job
  • Procedures for renting property
  • Negotiate a rental agreement with the landlord
  • Sign up for a credit card
  • Carry out some banking transactions (mortgage, credit line, debt)
  • Car rental.
  • Subscribe to cell phone, Internet or TV service
  • Writing a will
  • Enroll in a university or college

If you are asked for SIN when not required by law?

If you are asked for a SIN when it is not required by law, you should ask the person/company requesting your SIN, how your SIN will be used and with whom it will be shared. Without a satisfactory answer, explain to them that the law does not require you to provide your SIN in this case.

If the company or organization refuses to provide a service or product until you provide your SIN, ask to speak to your manager/person in charge. Actually there are some companies or organizations that do not know the proper use of SIN number. Once they understand, they will definitely change the way they work. Speak up, if you want them to change! 

If you are not satisfied with the response, you have the right to file a complaint with the Office of the Privacy Commissioner of Canada.

The importance of protecting your SIN numbers

The government has always noted the importance of keeping the SIN number secure and protecting it from fraudulent use.

If your SIN falls into the wrong hands, your personal information may be leaked and your privacy may be compromised. Bad guys can use your SIN to get benefits and Government payments, tax refunds or bank credits. Your personal information may also be disclosed to unauthorized persons, leading to identity theft and other sophisticated forms of fraud.

In fact, your SIN numbers can be misused in loans that can adversely affect your credit rating, and make it difficult for you to get credit in the future.

Your SIN might be used illegally when the Canada Revenue Agency requires you to pay taxes on the income you did not receive.

Therefore, you should notify Service Canada if your SIN is lost or if you suspect that your SIN is being misused. You should not use your SIN as identification and should not carry it with you. Instead, keep the card safe at home. Never give out a SIN over the phone unless the cardholder is the one making the call and knows for sure who he is talking to. Finally, never reply to an email asking for personal information like a social insurance number.
