Need advice! How should I quit?

I live in canada. I work as a barista. I want to send my boss a text saying “please accept this as my official resignation” or something along those lines. I get my pay checks at the end of the month, so basically soon. Can they withhold my final paycheck from me if I quit this way? Can they sue me for not giving two weeks notice? Shitty management is the reason and recently I had my final straw I can’t take it anymore, advice would be greatly appreciated
