How to Get a Social Insurance Number
To work in Canada you must have a Social Insurance Number (SIN). This 9-digit number is used to administrate government programs. You need it to pay taxes when your employer calculates your pay, and you need it to receive government benefits such as Employment Insurance or the Canada Pension Plan. You also need it for identification.
When applying for a SIN card, proof-of-identity is required. When you apply for a SIN card, you must show a primary document. If the name you are now using is different from the name on your primary document, you must also have a supporting document.
Your SIN is private and personal. Your employer will need to know your SIN so that deductions can be paid to the government for you. Always keep your SIN private, like a Personal Identification Number (PIN) on a bank or credit card. Never lend your SIN to anyone, and never borrow someone’s SIN to get a job.
The fastest way to get your SIN card is to submit your application in person at a local Service Canada Centre. To find the nearest office, visit the Service Canada website. Alternatively you can apply online or by mail. Go to the Service Canada website for more information.
