What is SIN?

SIN is Social Insurance Number, it is a 9 digit number is provided by the Canadian government that you need to work in Canada and access to government programs and benefits. One Social Insurance Number is issued to only one person and cannot be used by another one. Read more information.

In its name contains “N” stands for Number, so we don’t say “SIN number”, just SIN.

Who will need a SIN?

  • Canadian citizen
  • Permanent resident (PR)
  • Temporary resident (Foreign workers and students). The number starts with the number 9.

Canadian citizens and Permanent residents’ number is different from Temporary residents. If you are a temporary resident and you become a PR or citizen, you need to apply to a new number. Citizens and PR’s number is permanent which means you don’t need to re-issue it.

When will you use it for?

  • For working
  • To open a bank account
  • For access to government programs and benefits
  • To apply for a loan
  • For tax payment

To avoid scammers, only provide your SIN after you are hired for a job and provide it to the employer’s office admin when you attend at the office. Don’t send it over emails.
