So its a univeristy exemption then. But why complicate matters when you can apply for PR first? If your WP is a closed WP through LMIA you get extra CRS points. Plus you also get points for having relatives in Canada? Assuming you get invited through EE, processing time is around 3 to 4 months (average) based from users who posts their timeline in this forum. With a PR, you don't need WP or SP.As per enrolment services of my university I am eligible for domestic fee since I am a dependent of a Canadian citizen.
Are you not confident enough to get admission again in the future?
