Switching from a Study Permit to a Visitor Visa

[IrohK]

I have a study permit for a university in Ontario which expires at the end of this summer (Aug 2020). I've recently stopped going to classes, and plan to drop out officially and am interested in attending a non accredited private school in Quebec. The classes are shorter than 6 months, so any internationals would be allowed to attend as long as they have a visitor visa. My questions are:
-can I change my study permit to a visitor visa?
-can I attend this private school with my current study permit, as the class I want to take is only 10 weeks long (2.5 months) or is my study permit tied to my university here in Ontario?

Thank you for you're help!
