You and your employer must make sure you can work off campus without a work permit before you start working. If you start working off campus but don't meet the requirements, you may have to leave Canada.
Eligibility(资格) requirements
You can work off campus without a work permit if you meet all of these requirements:
you're a fulltime student at a designated learning institution(DLI)
you're enrolled in a postsecondary academic, vocational or professional training program or a secondarylevel vocational training program(Quebec only)
you've started studying
you have a Social Insurance Number(SIN)
If you're on an authorized leave from your studies, or you're switching schools and you're not studying, you can't work off campus. You can only return to work once you're back to studying.
Applying for a Social Insurance Number
Applying at a Service Canada Centre
Normally you must apply for a SIN in person, or have someone else apply for you in person. However, if you live in a remote area with no Service Canada Centre within 100 km, you are eligible to apply by mail. To confirm this is the case, you can use your postal code to check your eligibility on the Service Canada website or call Service Canada at 18662746627.
Note: There is no fee to apply for a SIN.
