Check the Canadian Code. Here in the States, we have to have an insulated ground wire in the feeder and branch circuits to pool equipment.

Which code rule refers to that?
The only restriction I can think of is that you can't run NMD in any conduit underground'
AND PVC can not be run in insulation.

I've wondered about this as well, and haven't had a straight answer. My thinking is you can't do the whole run in PVC, but shorter lengths for mechanical protection is okay.
12-902 says conductors shall be of types suitable for use in raceways as indicated in Table 19. And NMWU isn't listed as suitable for raceways.
But then, I haven't seen an inspector pay attention/call that either....when contractors have done that....but then they missed bigger problems than that.....

Only reason I can guess is the PVC acts as a chase underground in case they want to add/change anything without having to trench again?

This makes zero sense..are you telling me that if you are using a usei or useb for a service entrance relocate on a residence you have to run it in PVC underground? What a pain there would be no point to using a direct burial wire at all. Not to mention your sub panel is protected by an over current device, unlike the service conductors that are at the mercy of the transformers potential.

This makes no sense, Etobicoke follows the OESC just like the rest of Ontario does!

Do you guys use usei or useb in the ground for homes or do you have some stricter rules on service entrance wires?

In Toronto, hydro usually brings the service conductors right into the meter base for an underground service. But yes USEB is commonly used, as long as it is buried to the depth required by code and has red marking tape and the proper backfill it's no problem.

You aren't allowed to use two different fuses in a panel. I assume you mean breakers.
Your load calculations seem fine.
Make sure your underground wiring complies with section 68.
Your journeyman should be there to answer any other questions you have.
