Here's a basic map of water types in Canada. It doesn't seem as accurate as the ones of the US and UK, but it'll give you a good idea. if you can contact your local water department, they will know for sure.
There's a way to tell, sort of, just by using your soap. if you wash your hands with it, and they come out bone dry (not slick at all), you have softer water. If they are a little soft and "greasy" feeling, it could be harder water. But this method isn't 100% accurate
Welcome. Be careful with Dr. Bronner's, though. I know it's become the go-to soap for locks, but it is a castile soap. And castile soaps do not work well in hard water. So check you water type, or else you will end up with it building up residue in your locks
welcome but wouyldnt bother palm rolling it does nothing usefull but can caise permenant damage
