I took a 1 year PGDM course in Ontario, graduated on 17th Dec 23 and received my graduation certificate on the 28th Feb. I wanted to study for another year, applied for another course, received the offer letter, and extended my study permit until April 2025. However, I wish to work full-time due to a change in plans. Can I cancel my study permit and apply for a PGWP, or is it too late?
