Access to the Greffier site is reserved for parliamentarians and their researchers and assistants, who have access to the site. In principle, family does not have access to the site for security reasons.
If I understood your question correctly, I would have to say that the Greffier site will not necessarily be the answer. In terms of the calendar, the Greffier site will simply show it. In fact, this isn't true. It can be part of a solution, in the sense that the schedules for hearings and the calendar of upcoming events can be easily found. I'm sticking my neck out a bit, but I know that the whips' offices have their own parallel calendar system to ensure that members are present both at the National Assembly and in parliamentary committee at various times. I think they probably make more use of this calendar from the office of the whip for each political party.
