As an American working in Canada: Canada has a much stronger workers rights culture, and tends to have regulatory agencies that can produce results. (At the individual level, regulatory capture at the macro scale is just as prevalent, if not more so in the case of extractive industries).

It wouldn’t surprise me if vague clauses don’t get upheld, or if requiring an employee to be connected also comes with the responsibility of compensation and expenses. When I worked for a company that required me to do on-call on holidays or weekends, I was given an extra vacation day in compensation even if I hadn’t actually done anything but triage.

Work life in Canada seems generally much more balanced from an anecdotal perspective.
