For what it's worth, the latest revision of the Engineers Act in Quebec (2020, the previous revision was from 1962), has a much wider definition of engineering works and reserved acts, which does include software, if it can have an impact on the safety of persons. I am not a lawyer (mech engineer), but that's the message that the OIQ has been sending lately. It's unclear when and how they plan to start applying these new regulations.
