I can comment on all of the names you see here on the calendar. If they're listed on the calendar, it's because they've been requested to be present. As you can see, the ones who are in bold are the ones who are confirmed.
As of right now, it's difficult. I have not been able to find anyone for the one-hour slot before Minister Prentice. Perhaps the committee has additional suggestions of local representatives whom they may wish to have. It would be much easier to contact them than someone who is further away from Ottawa.
