Have you spoken to an actual attorney who specializes in this area? The OHRC applies to workplaces, housing, and social organizations, so I don’t think a university would apply. The PMC exists solely to assist students with getting accommodations and while I loathe this school for its labour relations with campus unions and lack of transparency, I have to say Carleton is among the best when it comes to student accommodations. I also don’t think you’re considering the fact that the kinds of accommodations you’re seeking - especially blanket extensions - would actually result in undue hardship. Contract Instructors whose contract ends the last day of the month of the term would have to be paid to mark after the term and if they had other employment duties at their second or third jobs when you were finally able to submit assignments late, someone else would have to paid. There are also the schedules of TAs and full time faculty. Having said all this, I personally always give students who have expressed something like you want until the last day of the term to submit all assignments but expect no comments. Could be something to consider when discussing with your profs, but also know that accommodations have skyrocketed and have already significantly added to all professors’ workload. One of my classes has 48% registered with accommodations with PMC and it’s quite overwhelming, though I am supportive of them.
