One of the first things to do as soon as you land in Canada is to get your Social Insurance Number (SIN). You cannot legally work without it.
What's a SIN and why do I need it?
In order to identify you in Canada, governmental agencies (federal and provincial) will use your SIN number. This 9-digit number will allow you to have a job, do your taxes, and/or receive governmental benefits (Canada Pension Plan, or Employment Insurance, etc.).
Who can apply for a SIN?
The following individuals can apply for a Social Insurance Number (SIN):
Children who are at least 12 years old can apply by themselves to have their own SAN.
- Canadian citizens or permanent residents,
- Work Permit and Study Permit (if allowed to work) holders,
- Individuals born outside Canada and registered under the Indian Act,
- Individuals residing outside Canada with no legal status in Canada and eligible for pension or benefits from Canada Pension Plan, Old Age Security or Régime des rentes du Québec.
Children who are at least 12 years old can apply by themselves to have their own SAN.

Protecting your SIN
Your SIN is and should remain confidential.
Someone having your SIN could use it unscrupulously to obtain your private information. It is therefore important to only divulge your SIN when necessary. When the SIN is not linked to you as its rightful owner, another person could receive your government benefits, tax refunds, etc.
The most common uses of your SIN are for your employer, your income tax information, financial institutions from which you earn interest or income, and government agencies.
