I've lived in CQ for two years and I'm switching to grad house this year. This last year I was lucky enough to get a single room which was awesome (very few in CQ). I had my own space and it was much cheaper than grad house. My roommate from first year had some very disturbing bathroom habits I would like to forget so the change was a godsend. Normally, residence allows you to renew your room if you're living there year-long. I was planning to renew this room until the end of my program. Unfortunately, they arbitrarily decided to reserve the building I was in and another for summer conferences. Everyone in these two buildings had to move to the other two CQ buildings. We were given very short notice about this and we had no say in matter of room selection. It was 'agree' or find somewhere else. To make matters worse, the move-out date is organised according to undergraduate student schedules; one week before writing this year's final exams I was packing my shit up and moving literally next door! That was fun.
I do have good things to say about CQ. Everything's new n' shiny so the apartments are nice. The rooms have decent sound proofing. To address mmd7's comment, I've never heard anything about bed bugs and there's no issue with heating here. Lastly, it is considerably cheaper than grad house. Personally, I don't think the benefits are worth it. Getting utterly screwed over during finals is a deal breaker for me.
I cannot stress enough that not bringing your car is a bad idea. If you live in residence you can get a parking spot in U-lot. Most of the spaces are electrified and they currently putting more in; I have never had trouble finding a spot. It gets packed but there's always been a plug-in available. The area furthest from the buildings is usually bare, so it's more about finding a good spot instead of finding a plug-in. Saskatoon is not a transit/alternate transportation friendly city. I agree with mmd7's post about bus service. The nearest grocery store is Sobey's on 8th street, which is about a 15-20 minute walk; you will not enjoy that in January. One important point to consider is that your clinical training can and will occur at locations far away from the university. Sometimes your schedule makes it stressful to get to these sessions on time even with a car. These sessions occur in groups of 2-4 so carpooling may be an option but that's a gamble.
