Its intense magnetic field is strong enough to overcome its blistering temperatures and “freeze” its outer layers into a solid crust. by MistWeaver80
They also tend to spin real quick! Conservation of angular momentum, coupled with a drastic reduction in radius, greatly increases whatever spin the star previously had.

Canada isn't mentioned even once in the linked article, so you'll need to look elsewhere for data relating to this specifically.
Quick peek from the biggest performance data related to national covid response, comparing USA and Canada for total cases/population, and deaths/population, USA was about 300% more severe in both metrics. So, it's likely the immediate effects on life expectancy follow that comparative trend.
here's the latest figures from statcan that I could find (2021 data may not yet be available), specifically relating to life expectancy impacts: https://www150.statcan.gc.ca/n1/pub/91f0015m/91f0015m2021002-eng.htm

You might be confusing combined theoretical peak loads with working demand loads in the real world.
Actual electric cars don't have 100 kWh packs, for starters. Most people are fine with half of that, 50kWh.
Also, very few people go to fast chargers with a 0% battery state. Most people also don't leave the fast charger with 100% battery state. In practice, it's more common to assume most drivers will charge 50% of the battery capacity, which for the sake of argument let's say is 25kWh.
Finally, the actual fast charge rate is proportionate to how close to empty the battery pack is.. a Tesla at 25% SOC topping up to 75% SOC might only start the charge at 100-150kW, tapering down below 50kW.
Yes, a very busy supercharging station in a dense city needs a fair bit of power (and may "peak shave" actual grid demand with on-site battery storage). For most cities however, it's actually not a huge load in practice, and easily implemented (which is why so many cities around the world have already installed them, even cities below 300,000 population like mine).

Reply to New research using advanced technology suggests heavy oil facilities in Saskatchewan are releasing almost four times as much methane as they report to government. by avogadros_number
What's worse, really:
You show the provincial government of Saskatchewan these thorough figures, they won't bat an eye. We have a highly conservative government here with seemingly little care regarding emissions and greenhouse gases.
In all of Canada, our province also has the highest greenhouse gas emissions per capita in the nation... We're #1 even without being honest about how much we're actually emitting (no doubt much more, all across the board).
(Edit: in gross emissions, we're #4 highest, but only the 6th most populous province).
It is rather embarrassing. Especially when considering the long term negative impacts Canada is sure to experience from climate change.
