How to receive a Social Insurance Number (SIN)

Getting a Social Insurance Number begins with getting an application form, and submitting relevant documents to support the application. Forms are available from Service Canada Centres, where any questions can also be asked.

Once completed, the application and documents can be taken to a Service Canada Centre. In many cases, a SIN number can be obtained the same day. In situations where geographic distance is a problem, applications can be mailed out.

For those who might require assistance, an immigration services company may be a good option. These are experts who can assist with the paperwork, and who can help to determine eligibility under the various categories that apply. 

Canadian Citizens, Permanent Residents, and Temporary Residents all need a Social Insurance Number to work in Canada. The SIN also allows for various benefits and/or services available through various government programs.

Children (12+) may apply for their own Social Insurance Number. Legal guardians can apply for a child who is under age. Refugee Claimants and Temporary Residents will receive a SIN that includes a specific expiration date.

When applying for a Social Insurance Number (or amending a SIN record) an applicant must provide proof of identity and legal status in Canada. In some cases, one or more supporting documents may be required.

Only original documents are accepted (no photocopies). Documents must be in English or French. Translated documents must be notarized, or can be authorized by a foreign government official or by a Canadian official.

When moving, it’s not necessary to inform Service Canada. However, when a name is legally changed, the SIN record must be updated under the new legal name. The new SIN record will be confirmed by regular mail.

In the event of legal changes to a Social Insurance Number, the former SIN card will no longer be valid and should be destroyed.
