To be eligible to work in Canada post-graduation, you are required to apply for a Post-Graduation Work Permit (PGWP) if you graduated from a Designated Learning Institution (DLI). You typically have 180 days to apply after receiving your final grades or before your study permit expires. If your study permit expires before you receive your final grades, you may either apply to extend your status as a student or leave Canada and apply for your PGWP.
For more information on DLI checklist and PGWP eligibility, refer to the Government of Canada’s website.
