Thanks for all the suggestions guys, I made it work! On my way back from Montreal to Toronto, and boy was it nice to see all the Teslas!
Did toronto to Ottawa, Ottawa to Montreal, Montreal to Toronto (en route now, currently at Port Hope Supercharging)
On my way to Ottawa, I charged to 100% from home, made it to a Kingston with 9km left (skipped Port Hope. Took about 15 minutes before any charging began!!! Almost had a heart attack that I was going to be stranded)...lesson learned: car takes a while to start charging when drained that low....charger to 369/381km at Kingston
It made it from Kingston to Ottawa with about 140km on the tank. Drove around a bit and charged at the Citoyen Maison 30amp (28km/hr) Citrique Electric charger in Gatineau (was staying at the four points Gatineau)...unfortunately it looks like they closed that gate off at 10, so wasn't able to get it back in after I took the car out for a drive. Had 130km left...parked on a side street...drove to Byward market (111km by that time)....found another J1772 charger there and went out for a bite to eat, returned with about 150km to get to Cornwall.
Issue #1: Cornwall supercharger - 6 stall charger....stalls 2a and 2b were completely dead. Stalls 3a and 3b are restricted to 52kw. Had to keep alternating between 1 a and 1b as the charge rate kept dropping significantly (overheating?)
Not a problem on the way to Montreal - I was the only one there
I topped up in Montreal - this charger was fantastic!! 92kw charging rate the entire charge up to 250km!
On the way back to Toronto, stopped at Cornwall again! Boy oh boy....I arrived, chargers were empty....charged at 1a....once it dropped, switched to 1b...right after doing that, 4 other Teslas pulled in back to back....and because there were only 4 active chargers, 1 guy actually had to wait for me to finish..., 2 of them were stuck and complaining about the very slow charging speeds, and the 1 guy who took over my slower charging 1a slot mentioned he was only getting 38kw but that eventually got up to full speeds once it had a chance to cool
Once I pulled out another one came in...basically this one had a line up!
Next stop: Kingston. Charger 2b is down! It won't insert! I arrived with all chargers empty, second I plug in (plugged in to 2a), 7-8 other Teslas pulled in!), all 5 of 6 active chargers filled up, and 2-3 began waiting...2a is best since no one can plug in to 2b to split the charge.
Came back after coffee and another 5 Teslas waiting to charge...
Left and now at Port Hope. Completely dead here! Getting great speeds haha
