The standard safe estimate is ~⅓ reduction when temps are around -25° to -30°, but it varies by car as to how much each degree affects that particular battery design.
You can use abetterrouteplanner.com and put in actual drives for different car models and in the settings you can set temperature, headwind, etc...
There's a few chargers in Hearst, ~250km to the east of Geraldton (210km east of Longlac). Most EVs can easily do 250km in -36° weather. That's one of the longest stretches of major highway in Ont without a charger, but it's certainly short enough for the average EV to do just fine even in harsh conditions.
There's multiple at Markville Mall, one is East Markham at the Scotiabank on HWY48, a set of them at the Hyundai Canada head office that are open to the public, and two Tesla supercharger sites in addition to the two you mentioned. That's just the DC Fast chargers, there's more than a few level 2 chargers at grocery stores, civic centres, and shopping malls.

And there's only 185 charging locations in Quebec (with 529 ports, which is NOT how they should be counted).
This is a bad analysis. Chargers per car is only one way to look at it. What about chargers per capita, chargers per road km, chargers person per land area, etc... oh? In all of those metrics Canadian provinces are leaders? You don't say.

I don't really know the area or charger quality, but there's a 50kW Ivy station in Geraldton, a total of 38km away from Longlac, Ont.
It's going very well in Vancouver and most of its suburbs.

This is an "opinion" writeup in a fringe publication. Why bother sharing such slanted views on our world?
There's no time domain or data source given in these. 0.2TWh could be tiny if it's annual, or huge if it's daily.
I assume it's merely that they import energy from neighbours.
Here's a map of who exported electricity in Europe in 2022, and who imported: https://www.powerengineeringint.com/wp-content/uploads/2023/03/EU-Interconnector-Map-H2-2022.jpg
Care to explain? They're a massive environmental leap forward from ICE vehicles. Many places in Canada need transport just like personal vehicles, and transportation is a huge portion of Canada's GHG emissions. So how else would we reduce that portion of our environmental footprint?
