I am an international student on a study permit which is valid until 2021. However, I changed my course from 2 years to 1 year after arriving in Canada. My course is ending April 2020. If I get my work permit then, what happens to my study permit as it would still be valid for another year? If it stays valid along with my work permit, can I use it to enroll into another course in Fall 2020? If accepted to the course in Fall 2020, will I lose my work permit based on the program of study completed in April 2020? Thank you.
