Given the unusual constraints that you face, you might want to look into a simpler solution - Just install a new pole with a separate meter and a breaker box out in the yard near where you want to park the car
I'm not sure how it works in Canada (or even at other locations around the US) but here we can get another pole and meter for just about any reason that makes good sense. Many folks have a separate meter for their boat docks, others do it when they install a new swimming pool, I know some who have a separate pole for a water well or a septic system which is a distance from the house and I'm sure if I needed to park an electric car some distance from my residence, it would be easy to get one for that too
The only downside is that there is a minimum charge for the electricity at that meter that you'll have to pay even if you're not using that much - Here I think it's about $15 per month, but an electric car should easily use more than that much every month, unless you're away on vacation or something most of the month
This would make installing a new Level 2 charger right where you need it much simpler - You'd just need a weatherproof unit and you could install that right on the same pole. Sounds like it might at least be worth looking into in your case
