Get a Social Insurance Number (SIN) in Canada

The number you need to work in Canada and to file taxes. It's free, and applying online is the fastest way. For citizens, permanent residents and anyone with a permit that lets them work.

The steps

1. 1

   Step 1: Find your primary document

   Citizen: a provincial birth certificate or a citizenship certificate. Permanent resident: your PR card or Confirmation of Permanent Residence (COPR). Temporary resident: a work permit, or a study permit that says you may work.

   Step 3: Apply online

   Upload clear digital copies of the originals with the application form (NAS2120). There's no fee. Check everything before you send it: an application can't be edited, only sent again.

   Step 5: Keep the number private

   Your employer and the CRA need it; most others don't. A SIN starting with 9 expires with your permit: when you get a new permit, update the SIN with Service Canada.
