Need feedback on DWV plumbing rough-in layout

Fellow RFD, plumbers and code experts, I need some feed back on the DWV rough-in layout i have made for my basement bathroom. specifically whether it meets the Ontario code or not.
A couple of concerns i have:
  1. The clean outs are facing sideways in the wall and will be covered in the drywall. I have seen several videos/posts doing that in Ontario, but I still wonder if this will cause any issues with the inspection.
  2. At the vertical to horizontal connection of the bar sink stack, i have used a long sweep 90. Will this be ok or shall i use two 45s. I would prefer the 90 because it takes smaller vertical space.
  3. I have used 1.5" pipe for vents. I keep seeing that 2" is needed for toilet, but everything i find on Ontario code suggests that 1.5" will be ok.


Colors represents sizes:
Magenta: 3", Yellow: 2", Green: 1.5"
