Off-campus work is work that takes place on any location outside the boundaries of the campus at which a student is registered.
Some volunteer positions and internships (paid or unpaid) may be considered work by IRCC – for example, if you volunteer for a job that is normally performed by paid employees (photocopying, customer service, etc.), it is considered work regardless of whether you are paid or not. Review the meaning of work according to the IRCC definition to decide. If your volunteer position or internship is considered work, you must have the appropriate work authorization before you start.
