So if you're graduating in June of this year, would taking some courses in summer school (just the spring term) affect that? Classes for first term end on June 20th... which is like eight days after my graduation.

Yes it will. If you need to take summer classes you will graduate in November instead.

is that even if you don't need the courses to graduate? (just courses for fun, I'd be eligible to graduate without them)

Update just in case anyone else is looking for answers:
I went to the office of the registrar to ask them. If you don't need the courses, you can take summer school and it won't affect your graduation date, you'll just be registering as a "continuing" student. However, this makes you ineligible for OSAP.
