Can we do a masters while working fulltime in Canada in Work permit? If so can we able to complete in one year to boost PR score?
Unfortunately you cannot. A master’s program is 2 years long, and your work permit allows you to take up courses that are shorter than 6 months. To study in Canada, you must apply for a study permit. Your exiting work permit may be cancelled. After you have secured a study permit, you can then apply for a work permit.
