openbsd is supposedly based in canada
if you’re feeling particularly bold
https://www.openbsd.org/faq/faq5.html don’t know if building from source would run better?
modern debian worked GREAT on my 2004 desktop with (iirc) 512mb RAM (could have been 1GB actually, maybe 1.5GB, it’s been ages) and some Pentium 4 (this was 2022 or 2023 i think, but it was the newest debian at the time). i think i started with a minimal install and then used awesome window manager. don’t think i used a login manager but used startx or something. ran better than a lot of new computers these days
