Who Needs a SIN?

The SIN is required for all individuals living and working in Canada, including:

• Canadian citizens
• Permanent residents

• Temporary residents (including international students and temporary workers)

Regardless of immigration status, anyone who needs to work or access government services in Canada must obtain a SIN.

Those not eligible for a SIN, such as non-residents who need to file taxes in Canada, can apply for an Individual Tax Number (ITN) for tax purposes. An ITN is a temporary number that allows individuals to meet their tax obligations in Canada.

How to Apply for a SIN

Applying for a SIN is a straightforward process, which can be done online, by mail, or in person at designated Service Canada offices. Here’s a step-by-step guide:

1. Determine Eligibility: Ensure you meet the eligibility criteria. You must be at least 12 years old and a resident of Canada.

2. Gather Required Documents: The documents required depend on your status:

   • Canadian Citizens: Birth certificate, citizenship certificate, or a valid passport.
   • Permanent Residents: Permanent resident card or immigration document issued by the government.
   • Temporary Residents: Work permit, study permit, or visitor record.

3. Complete the Application: You can apply online by filling out the application form on the Service Canada website or by downloading a paper application and sending it by mail. If applying in person, you can visit a Service Canada office with your documents.

4. Receive Your SIN: After processing your application, you will receive your SIN by mail or at the office, depending on your application method.

The validity of your SIN is based on the permit that authorizes you to work in Canada. Every time you extend your work or study permits and want to continue working or filing your taxes, you must renew your SIN with the new or renewed permits.

Note: International students' SIN starts with '9', which enables employers to know that they are temporary residents in Canada.
