True, 6/3 is probably the wisest choice long term especially if I finish the basement eventually.
I was not aware, thank you! Wow, the ESA website and fee guide is super confusing. All I managed to find was that a homeowner's permit is $79 but not sure how much the inspection will be?
I checked out conduit parts at the home depot yesterday. Does anyone have photos or advice on the conduit parts that they used like this one which I guess would be good for bringing the cable through the drywall into the garage to meet up with additional conduit up to the receptacle?

Sent you note via direct conversation to give me a call -- I can guide you through the major decision points quicker than reading the whole code book...
ESA sheet can be confusing for sure -- fortunately there is a single code for the EV charger. The inspection is part of the permit (so long as it passes first time -- if not, there will be an additional charge for each visit).
The wall penetration is the tricky part as there is a limit to what types of cables and conduits can pass through insulated areas. What I did was EMT (metal) between the HPWC and the disconnect, flexible non-metallic (liquid tight) between the disconnect and through the wall (stops about 1 inch after penetrating the surface), then NMD (regular cable) inside the house. The reason I chose the flexible conduit for the penetration was mostly to simplify sealing the wall penetration and making the "tight turn". Any cable in a junction box must be anchored as it enters the box, and you don't want that anchor inside the wall penetration as it's a mess to seal, etc). Inside the conduits, it must be individual conductors, so I stripped the outer sheath from the NMD for passage through the flexible, and I used individual T90 conductors from the disconnect through the metal conduit to the HPWC.
I am not sure about poly conduits -- most of the stuff I saw suggested it was largely for outdoor, but I have seen it used indoor as well in some places (not necessarily Ontario).
The other option is armoured cable -- which depending on the run length, might be simpler because then you don't need conduit. However, conduit isn't that pricey. I also have a few left over parts for the EMT if you are in the same end of town as me (far west end).

My inspection is this Wednesday -- finger crossed I got it all right.
