I'm in Kingston now, sadly charging for 2 1/2 hours at the Best Western. I'll drive by the SC site on the way out and report on the status - around 3:30.

Poor lonely transformer still waiting for a base and poor lonely supercharger stalls still waiting for power...
Sad, sad state of affairs. This reeks of Quebec style bureaucracy! Or some union hangup. Thanks for the updates guys. I guess if the DS is being honest then tomorrow is the big day. See? I can be optimistic too you know....
I had to change a hot water tank today in one of our rental apartments and briefly I considered plumbing it all, cleaning up and making it look like it was working but not plugging in for a few days or weeks... but decided I like hot water so I just finished the job. I think I might volunteer to become a SuperCharger team guy.... I can make 'em git er done boys!

From what I can tell, the construction crew did a great job and pushed hard to finish their part on schedule in 4 weeks. What's holding things up now is anyone's guess, but they had lots of time to put together a project plan and work out the coordination and timing of the final tasks, so this delay is really inexcusable!
My drive from Toronto to Ottawa today was 8.5 hours (vs. 5 in an ICE car), starting full and arriving with less than 60km into Kingston and less than 30km at home, and with no stops other than 2.5 hrs of charging. I had to go 100 km/h on the 401 most of the way, and then 70 on Hwy 15 home. It doesn't make Teslas look good when people see them driving much slower than traffic and pulling over to let people pass. I'm really hoping that none of us have to do that ever again!

If it can make you feel better Peter, my wife and I went to Toronto (from Montreal) last week. It took us 12H to get to our hotel (door to door). Leaving Montreal with the battery full, we still stopped at Cornwall to top it off (40 minutes stop because the last few km are Reeeeaaally slow, even on a SC!), then we drove to Kingston at 100km/h. We calculated a 30% buffer to get to Toronto because of the cold, and because of that, we waited 4H at Tom's place (that's vveeeery long, even if the fireplace is nice). We arrived at the Toronto SC with 1km left, driving the last hour or so around 90-95km/h.
On the way back, in order to save a bit of time in Kingston (the area next to the Best Western is far from being attractive! there's really not much to do), we drove exactly 92km/h from Toronto to Kingston. This was the first time I actually was mad-bored-ashamed of driving a Tesla... We must have been passed by 1000 cars and trucks!! What an awful publicity for Tesla! This time in Kingston, we charged for a bit over 3H, BUT, on Sundays, both Tom's place and the restaurant at the Best Western are closed... so we had to find a place to wait in no-man's land... PLUS the parking spot next to the charging port was ICED (the lady at the front desk told us she would not contact the person parked there because we weren't bring BW any business that day (both restaurants were closed!!)). We had to park on the handicap spot (another good publicity for Tesla). Stopped at Cornwall to charge up again because we did not have enough to make it to Montreal... it was a pleasure seeing the range go up faster than it took us to drink a coffee at the Ramada hotel (and talk to another (pissed) Tesla owner from Toronto who's been traveling Toronto-Montreal since January!!). Cornwall-Montreal was... fast! Total traveling time for the way back: 11H!!

Wow, that's painful! And it shows that we really do need another SC somewhere between Brighton and Port Hope.
Well for me at least, I won't go through that kind of trip again. The SC had better be ready for our next trip (Dec 26); if not, we're taking the Prius.
But that's surprising about Kingston to the Toronto SC taking your entire battery. Do you have a 60kWh?

No, we have a S85 (no dual charger!), and to top off the battery at the Best Western, we would have waited at least 2-3 more hours. We figured with 30% extra rated range then the actual distance, we should be safe... NOT at 100km/h when it's freezing outside!
On the way back, we took a 40% buffer.
painful indeed!

OK, I misread your post - thought you left Kingston at 100%.
I tend to use a fixed buffer, not a percent. I did the charge calculation like this today in Kingston: 150km to our destination plus 50km buffer (snowy day) = 200km. From Toronto to Kingston we used 222 Wh/km, so I figured it would be around 215 from Kingston to Ottawa on a slower road, so 200 * 215 / 188 (consumption for Rated Range) = 229, so we charged to 230 Rated. It turned out that we got more like 225 Wh/km due to increasing snow even at 70 km/h, so we got home with just 24km.
Our one mistake is we probably should have topped up (or nearly) at the Toronto SC on the way by. We started in Etobicoke, so the top-up would have just taken 10-15 minutes and would have saved us probably 1/2 hour or more in Kingston.

If you go through the kW, etc, in an 85, the time to leave the Supercharger is approximately when the Amps are at half of what you can charge at the next L2, 240V site, 208 vs 240 is in the noise. So if the charging in Kingston is 70A, leave Toronto when the charging drops below 35 Amps on the Supercharger; beyond that it it faster to charge L2.

I'm trying to understand this. Leave the SC when the amps drop below half of your next L2 station? How does this have any correlation? Forgive me my brain has been full for years.

Here is the math:
- 85's finish charging at about 400 Volts. DC charging efficieny is 100%.
- AC Chargers input Voltage is 240 Volts. Conversion effieiency is about 90%.
- Power = V*I
- For equal power in to battery: 400*I[SUB]sc[/SUB] = 240*I[SUB]ac[/SUB]*0.9
- I[SUB]sc[/SUB] = 240*0.9/400*I[SUB]ac[/SUB]
- I[SUB]sc[/SUB] = 0.54*I[SUB]ac[/SUB]
For 208 Volts, I[SUB]sc[/SUB] = 0.47*I[SUB]ac[/SUB]. So when the Supercharger Current is about half of the 208-240V AC Current, the Charging power is equal. Before equality charging is faster on the Supercharger. After equality, charging is faster on the AC charger after you have used some miles driving and can accept the full AC power.
Clear as mud...

"Mad-bored-ashamed to be driving a Tesla"
Nice post. I hope Elon reads this one...he will cringe (and should). This is not the customer experience Tesla is striving for, nor does it seem to be the reality in other markets. This is a Canadian issue. This should have been a PRIORITY for some time...Montreal to Toronto at the very least. Who at Tesla manages operations in Canada? They need more resources allocated to this...a charging specialist to oversee rapid and efficient SC implementation and to develop a secondary HPWC network with municipal/business partners.
Have them call me...I'll do it!

Why not simply set the car to show you the power being charged at? (On the page that allows you to select units). Once the charging display shows the power below, say, 14 kW, if you're expecting to charge at a 14 kW L2 station (200 V, 70A), then you might as well leave.
For me, the calculation would be simple, as I have a single charger. Even close to full the Supercharger is still going to be beating 8 kW (200V, 40A). And for sure it's going to beat 6 kW, which is what you get from most public charging stations (200V, 30A). Here's a sample showing a Supercharger topping the battery up to full, and it's still charging at 6 kW ! (15A @ 403V)

Before you get all whiny about this: there are some large markets where this is definitely the case. Try driving a Model S out of the "Texas island", for example, or outside St Louis or Cincinnati or, heck, even Boston. Metro St Louis has 2.8 million people. Boston has 4.6 million. Houston alone has over 6 million.
Good coverage takes time.
