This guided wizard helps you understand how to get a Social Insurance Number (SIN) in Canada. It is a learning guide (not an official application).

Important: Always apply through Service Canada. This wizard is only to help you understand the steps and what to prepare.

Understand what a SIN is used for and how to keep it safe.

I understand a SIN is used for work and taxes

I will keep my SIN private and only share it when required

Tip: You usually only share your SIN with an employer (payroll), CRA, and some banks for tax slips.

Pick your status in Canada and confirm you have valid documents.

Temporary residents often receive a SIN starting with “9” and it may be tied to your permit expiry.

Make sure your documents match and you bring originals.

I will bring original documents (not photocopies)

My name and date of birth match across my documents
