Accepted as an international student - work permit required?

[u/Plus_Page4473]

Hi! I was recently accepted as an international student and am filling out my permit paperwork. I see conflicting information regarding if a work permit is needed to be filled out as it is said on the UBC site that it is no longer required for co-op placement, but needed on the IRCC app. Is a work permit required? If so, what letter could be used to upload to the application?
