Time to think about getting a Social Insurance Number.
The Social Insurance Number (SIN) is a nine-digit number that you need to work in Canada or to have access to government programs and benefits.
A SIN is issued to one person only and it cannot legally be used by anyone else. You are responsible for protecting your SIN. Store any document containing your SIN and personal information in a safe place—do not keep your SIN with you.
If you are a Canadian citizen, a permanent resident or a temporary resident, you need a Social Insurance Number (SIN) to work in Canada or to receive benefits and services from government programs.
Children who are 12 years of age or older may apply for their own SIN.
Parents and individuals who are legally authorized to act on behalf of the applicant (for example, a legal guardian or legal representative) can also apply for a SIN for children under the age of majority in their province, and adults in their care.
To apply for a Social Insurance Number (SIN), to request a confirmation of your SIN or to amend your SIN record, you must provide primary documents that prove your identity and legal status in Canada.
If the name indicated on your primary documents is different than the name you are currently using, you must also provide supporting documents.
If you are applying for someone else, you may need to provide additional documents.
