My son is a high functioning aspie who currently has typing and some related accommodations that he uses in school. I anticipate him needing those in college as well as a single accommodation.
I see that McGill has an office for this sort of thing, but I’m wondering about the reality. I also keep reading that McGill doesn’t do hand holding or administrative support. So what happens when a first year wants a single but not to be socially isolated? Does McGill take an active interest in figuring out how to manage that or does it say too bad, so sad, you’re own your own? What if there’s a problem with a professor and an accommodation?
I expect my son to advocate for himself and to take an active role in getting what he needs, but what happens when he seeks help from the institution?
I can help a bit…hopefully others can add much more detail. My oldest son is a U0. Was on an IEP through 10th grade and still every once in a while struggles to get intricate social dynamics. He is in a single in the Upper Rez (Molson/McConnell/Gardner). It’s proven to be a good fit. He can close his door when he needs space but the dorms are very social. Kids are hanging out all the time and he feels like he always has someone to eat with, hang out with, etc. Frosh was good for him; they did a nice job helping the kids form bonds. All of that said, I know the spectrum well enough to know that every kid’s needs are different. I’d dig in with McGill directly and see if they do what your son will need. Helping him get things set up in the first place is a good thing for you to do with him. You are right, after that he will need to (mostly) advocate on his own. Feel free to message me if I can be of any additional assistance.
For the record, my son has stated that choosing McGill is “the best decision I’ve ever made in my life”. I know there will be lots of twists and turns and bumps along the way but that comment alone makes me happy. 
Thanks! That’s good to know. He’s only a junior now, but I may come back to you next year.
