The short answer is that you need a CIDA minister, a minister for international development. I'd argue that one of the failings of the legislation is that it doesn't leave open the possibility of a lot more ministers. In the British system, they have six or seven or eight in their Foreign and Commonwealth Office portfolio in addition to DFID.
My sense is that if you're talking about a $2 billion program for Foreign Affairs, and a $4 billion program for CIDA, the more political sensitivity and political control you have over that, the better.
I don't know about the limos, but I would argue for lots of aircraft to have people go to see what's going on all over the world, free and clear. With the political control, you have the prospect of adjusting really quickly. The Minister of Foreign Affairs may not always be available. There are so many standard fixtures on the international agenda every year that you'd better have a whole bunch of other ministers who can go to do things at the ministerial level—to speak for the government, to speak for the cabinet in other countries.
