His friend of a friend certainly knows better...than you. Transition glue is perfectly legal in Canada, according to 7.2.5.11 of the Ontario Building Code:
View attachment 28146
I am looking for some advice on exactly where to put the vent(s) in this situation. I want to do this properly and use whatever sizes of pipe required by code. I have the chisel on hand so I will do what is necessary regarding distances from traps to the vent.
This is my own personal basement.
Two pictures included are side by side.
The size of the room is about 8' X 5'
Shower on the far right, toilet in the middle, sink on the left.
The run from the shower drain to the main sewer line is about 8.5 feet. Distance from the toilet after it makes the bend is about 5.5 feet. What I planned so far is to run the shower in 2 inch abs, to a wye fitting (2x3x3) from the toilet which would be 3 inch and that would run to the main line. What I do not know is exactly where to put the vent or vents and what size they should be. I assume the vanity can be hooked up basically at the wall tying into the current drain and vent as it is right now.
The vertical pipes are the drain from the kitchen sink upstairs and to the right of it is a vent to the roof. Previously, there was a laundry tub hooked up where you see it cut.
Also, the builder looks to have used green PVC. I don't see that sold at big box stores. Is it the same grade as white? Should I be running all this in PVC or ABS? Can I use white?
If my sizes or plan is incorrect or not ideal please let me know. I'm sure there is more than one way to do this, so I am looking to keep it as simple as possible.
Thanks very much.

No new vent needs to be ran. You can transform your drains into a WET VENT for your new bathroom:
1. Cut out the 90 from the stack and cut your vent and kitchen drain
2. Use 4x3x4" ABS Cleanout Tee with plug
3. Use a 3x2 ABS flush bushing for top of cleanout Tee
4. Use a 2x2x2 ABS wye
5. Use a 2x1.5" ABS bushing for top of wye; Kitchen sink drains into the top of the wye
6. Use a 2" ABS 45 street to the side of wye and run a 2" drain
7. Use a 2x1.5x1.5" ABS wye on its back, 1.5" ABS 45 street on top to 1.5" vent, other 1.5" to a 1.5" drain, 1.5" cleanout, and to 1.5" trap arm of LAV
8. Use two 4" ABS 45 elbows for a long turn from vertical to horizontal drain under slab
9. Use 4x4x3 ABS wye off the sewer drain
10. Run a new 3" ABS drain off the wye
11. Use a 3x3x3 ABS wye off the new 3" drain
12. Run 3" ABS pipe for the toilet drain
13. Use a 4x3 ABS Closet 90 for the toilet turn
14. Use a 3x2" ABS flush bushing on the wye for the 2" shower drain
By upgrading to a portion of 2" pipe above the clean out, the drains below the cleanout becomes a WET vent for your new bathroom group. Alternatively, and to further appease the plumbing gods, you can enhance the configuration above by adding a 2x2x1.5" wye to near the top of the shower drain and vent off the centre line, tying back into the MAIN vent line above the LAV with a 1.5" sanitary tee (make sure the TEE is >6" above #7)
