There's KOHO for Canadians, still not a proper Privacy.com replacement but you get two Mastercard cards (one physical & one digital) and they are refillable via Interac payments.
When doing trials, I set a few dollars on the card to ensure if they try to do a 1$ transaction to verify the card and I'm good to go. Even if I forget to cancel, the payment won't pass.
I'd say lack of marketing and higher price tags. Money / Performance ratio is also better with a decent Thinkpad.
Some of these options can't (or not without high markups) be bought and shipped to Canada.
Because it use common hardware and bought "en masse" by enterprises; they tend to be more supported with FOSS than other options.
I've been happy with my used T480 so far.
