The "Easy" Pro-active Basics
Some reasonable adjustments have a long lead time, so need to be done proactively. I would expect:
Public website that works for all users (Conformance to WCAG at Level Double A plus)
LMS that works for all students (If yours doesn't, check out www.atutor.ca - open source from University of Toronto and fully accessible)
Academic staff (including sessional staff) trained to produced accessible PowerPoint, Word and Excel as a matter of course
Rooms etc. that are physically accessible and allow choice of seating
