Really, the personal calendar of members is left up to the member and his or her staff. I think most members have a staff person who's responsible for scheduling. Many times those staffers are in communication with the member's family to make sure that they're aware of any events. Sometimes they're consulted with, because a lot of events are in the evening or on the weekend.
To my knowledge, and in my experience, the constituency staff, as well as the staff at Queen's Park, work in coordination with each other in developing the calendar. But beyond that, I would say for us, for the assembly staff, we have little or no involvement in members' personal calendars.
