Social Insurance Number
The Social Insurance Number (SIN) is a unique nine-digit number assigned to one single person. This number is used to identify people who work in Canada, and who need to access government programs and benefits. All newcomers to Canada should apply for a SIN.

In order to get a SIN Card, you need to:
