A SIN beginning with the number 0 or 8 should NEVER be accepted. If presented with a SIN card beginning with these numbers, contact Service Canada or the RCMP immediately.
TEMPORARY SINS (900-SERIES)
SIN cards beginning with the number 9 (also referred to as 900-series SINs) are not considered permanent and are issued to temporary foreign workers who are neither Canadian citizens nor permanent residents. These SINs are valid only until the expiry date printed on the front of the card.
Expiry dates on 900-series SINs were introduced in March 2003 to illustrate the end of the person's authorized ability to work in Canada, to a maximum of five years.
A 900-series card holder without an expiry date must provide valid immigration documents to obtain a new temporary or, if applicable, a permanent card. (900-series SIN cards without expiry dates were no longer issued after April 3, 2004.)
Remember, employers must see the employee’s SIN card within three days of hiring. If the SIN begins with the number 9, employers must now do two things:
1. Inspect the card to ensure it has not expired. If there is no expiry date, the card is no longer valid.
2. Review the valid work permit issued by Citizenship and Immigration Canada (CIC) to ensure the employee is authorized to work. Review the terms and conditions of the work permit, which will include dates, authorized locations and any restrictions. (For example, foreign students are often provided with a temporary SIN allowing them to only work within a certain distance from campus.)
If the work permit has expired or will be expiring within the next four months, the employee must apply for an extension of the work permit with CIC. Once the work permit is approved, an application can be made for an extension of the SIN.
A work permit is needed for most temporary jobs in Canada. However, there are some temporary jobs that do not need a temporary work permit based on the job function. Some examples include foreign athletes and coaches, clergy, performing artists, public speakers and full-time students working on campus.
