Post-graduation work permits (PGWPs) are open work permits given to international students who graduate from a Canadian program of study. PGWPs allow the holder to work for any employer, for as many hours they wish, anywhere in Canada. PGWPs are valid for between eight months to three years and are a great way to obtain valuable Canadian work experience. Once an applicant has work experience in Canada, it opens a lot of opportunities to obtain Canadian permanent residence.
