When the legislation is passed, providing medical assistance in dying will become a legal activity. Providing information to a person to engage in a legal activity is legal, so there's no need to basically put in law that it is legal to provide information to tell someone to do something that is legal.
If you provide information as to how to undertake a legal activity, as to how to find out how to obtain the medical services of medical assistance in dying, that is legal. It's self-evident, so you don't have to say it.
