I have just a couple of thoughts.
We could probably deal with the Transport Canada input or discussion with them in half an hour, and leave two and a half hours to spend with witnesses. I like the idea, then, of adding some time subsequently to consider what we're going to send back to finance.
I'd also recommend that we ask the Transport Canada people to be here in the room to hear what the witnesses have to say, rather than just coming in for their slot. I think that will build a context and make that part of the meeting more efficient.
