Your study permit (SP) authorizes you to work on the Polytechnique campus and its buildings.  The employer may be the institution, a department, a student association or a private company. Working on campus as a self-employed person also satisfies the conditions of on-campus work.

Immigration, Refugees and Citizenship Canada (IRCC) specifies that:

"Students may work as teaching or research assistants on campus or in a building affiliated with the institution but located outside the physical boundaries of the institution’s campus, such as a library, hospital or research facility. This work is allowed, provided it is strictly related to the student’s research grant."

To be eligible to work on campus, you must:

• Hold a valid study permit authorizing on-campus work;
• Be enrolled in full-time studies during the regular academic year:
  • For course-based programs (BEng, DESS, MEng): Fall and winter sessions. Students retain the right to work on campus if enrolled part-time in the Fall or Winter terms, provided it is their last term in their program. 
  • For researched-based programs (MASc, PhD): Full-time study in all sessions;
• Work in a job that meets the criteria for on-campus work.

The Immigration and Refugee Protection Regulations do not set a maximum number of hours that students can work on campus per week.

Because of the first point, exchange students who come to Polytechnique for a single session and who do not have a study permit are not eligible for on-campus work.

In order to work on campus, you will need a social insurance number (SIN) prior to starting work.

Unfortunately, we do not have a list of jobs available on campus. We therefore suggest preparing a résumé and a cover letter, then visiting the various departments and services in person to inquire about employment opportunities and submit your application.

You may wish to contact the cafeteria, the library, the COOP bookstore, the IT Department, your academic department, the Student Services Office, and other campus services.

Graduate students can also contact their academic department to inquire about opportunities for exam invigilation and employment related to teaching assistantships.
