Tax ID / National Number in Canada for Newcomers

Settle task: Social Insurance Number (SIN). Official links below. This is not a determination that you qualify.

In Canada, people who work need a Social Insurance Number (SIN). Service Canada issues it. Apply online or in person using the Government of Canada instructions. A SIN is not proof of immigration status by itself.

Which ID this page means

Canada’s work and tax ID for individuals is the Social Insurance Number (SIN).

Official channel

Employment and Social Development Canada / Service Canada publish how to apply for a SIN. Use those pages for eligibility, documents, and whether your SIN has an expiry date tied to a temporary status.

What this page does not do

It does not decide whether your immigration document allows work, and it does not replace Service Canada.

How it works

  1. Confirm your immigration document allows work if you are applying in order to work.
  2. Follow the Government of Canada SIN application instructions.
  3. Keep the SIN letter or card safe; do not treat a SIN as a public ID number.
  4. If your status is temporary, check whether the SIN has an expiry date.

Who this helps

  • Temporary residents
  • Refugees
  • Canadian citizens
