Basement plumbing venting

[Knuckles]

Hi all, long time lurker, great info.

Currently planning a basement bathroom, vanity, WC, shower. Looking for advice on the venting.

Location is in Ontario, Canada.

Wondering if:

1) Wet vent is ok from WC to shower?
2) Is the 1.5" vent required for the vanity, or will the wet vent supply venting for this?
​

Let me know if any further info is required.

Take care!

Based on searching forum and google, I believe the wet vent will serve the toilet and shower fine, but need to stick with the 1.5" vent for the sink/vanity.
