How to Get Your SIN in Canada

⏱ Time to get it: Same day (in person) or 2-3 weeks (online)
📍 Where: Service Canada office or online at canada.ca

WHAT YOU NEED
Documents to bring

HOW TO APPLY
Step-by-step guide
Step 1 — Find your nearest Service Canada office
Go to canada.ca/service-canada to find the office nearest to you. No appointment needed for SIN applications.

You’ll get your SIN number the same day. Write it down and keep it safe — never share it unnecessarily.
