I’d add that, while not strictly required, one of those total car snow covers really does come in handy: https://www.amazon.ca/kayme-Waterproof-Protection-Automobiles-Universal/dp/B09FLKGLCW

Seriously, clearing snow isn’t just for your visibility. It’s illegal here (and presumably other places) to leave any snow at all on your car because it will come off and is very likely to affect the visibility of another driver at high speeds.

Have a snow blower? Don’t wait until the day before to see if it still runs. Make sure you have gas for it

That reminds me, I should set a reminder to charge the batteries for mine.

Also your car needs real winter tires, preferably studded.
