Normally I wouldn't. I understand why you would ask the question and it is worth asking. The reply below will address that question in detail.
However, the Rideau Centre supercharger is the third level down at the Rideau Centre. Five minutes from the time you enter the garage to the time you plugin. The physical location for those transiting the Trans- Canada highway takes 15 minutes on a good day and 30 on a bad day. For those not familiar with the Rideau Centre there are multiple entrances and garages that don't connect so navigation is an issue unless you know exactly where you are going.
Because it's down 3 levels in a reinforced concrete structure, a cell signal is iffy at best. The garage can be closed down/access denied for a number of reasons - full/Covid19 measures. Good luck trying to get a hold of someone to explain why you need to enter the garage when you really really need a charge with your SoC at 5% on a very cold day in January.
The idle fees can be somewhat arbitrary. Stories abound about high fees when there are less than 50% full when you really need that extra boost. Granted not that important that Perth and Bells Corners are up and running
This is a 72 Kw Supercharger so not all that fast, and many find that the charging speed is much lower even when the SoC is around 20-30%.
The cost to enter this parking garage is steep by Ottawa standards is fairly steep, though nothing compared to New York City or Washington D.C.
There are also social issues here at work. The elevators coming down to the Tesla Supercharger are just inside the doors of the Rideau Centre where a lot of folks with social, mental, and health issues can easily access.
Some quotes directly from Plugshare
"Charger works well, but the location is annoying. Parking is paid, it's at the third level down, and there are a bunch of skateboarders."
“Be careful planning your trip around this Supercharger. If you come here on a weekend, there’s a good chance that they’ll determine the parking garage is full and will lock the entry gate so that you won’t be able to get in. Plus it’s a 4$ parking fee to use the garage for a charging session. Terrible placement of a Supercharger on Tesla’s part.”
“Max around 55kw, only 2 other stalls were open”
“Charged idle fees even though never at 50% capacity...”
“6’10” entrance. Had to take bikes off roof to get in. Also had to pay for parking.”
“Maxed out at 58kw, Never got the rated 72kw so not super fast. parking is now $2/30mins. Was my 2nd visit on a weekday, pretty quiet both times only saw another model S and model 3 as I was leaving via the labyrinth. Also takes about 3-5mins to get down to P3! In about 30mins with 58kw you will get about 150km/30mins. So in short if you can find somewhere else to charge off peak electricity is cheaper then the parking.”
“Not free parking. In p3 - no reception to check on car’s status with phone. The gate on the way out of the garage could not open - cars waiting there for attendant.... ONLY charger in Ottawa. Not free ...”
“Hard to find. Parking entrance not well marked. Every time I’ve come here there’s lots of traffic around entrance and once in the garage it’s tight corners and sometimes congestion getting down to P3. Station 1A was only charging at 48KW. Switched to 1B - now charging at 65kW. Still not optimum. With all the M3s recently released in Ontario, and bring the only supercharger in the Ottawa area, this station definitely getting busier. 5 cars charging now. Another pulling in”
To recap:
- Too fast for a long period of shopping or attending a conference or meeting (when they resume)
- Too slow - rated at 72 - most times significantly less
- Too far from highways
- May be locked in/out
- Hard to find
- Expensive parking
- Dangerous
- Other alternatives for Level 2 chargers nearby - for example, the Westin hotel has a Tesla destination charger in the same complex and there are two J1772s at the Rideau Centre for those who will be more than an hour.
- Poor cell coverage
- Arbitrary idle fees
- Hard to access if you have a roof bike rack
So that's the argument. I believe that this was Tesla's idea of locating a flagship Supercharger only minutes away from the Parliament of Canada. I would think that in hindsight that Tesla would not place this there now. Down at the bottom of a parking garage, not too many movers and shakers are going to see it. Chances are a lot more skateboarders (nothing against skateboarders) and homeless people looking to avoid Mall security will be there.
