Studying must be your main activity. However, you can work during your studies under certain conditions.
Working on campus
You can hold a job in an office or room located on the campus of your educational institution. For example, this includes:
A library;
A research establishment associated with your educational institution;
A cafeteria.
For conditions, see the Government of Canada’s Work on campus page.
Working off campus as an intern
You can work outside your educational institution as part of a paid or unpaid internship. This internship must be compulsory as part of your Québec study program.
You usually need to obtain a cooperative work permit from the Government of Canada.
