Since you said my name first, I'll go first.
I'm not an expert on the political aspects of these things, but my feeling would be that there is some sense in having it correspond somewhat to jurisdictional boundaries, because that's where the money and the decision-making comes from. However, on the other hand, of course, I do think that these units have to work together.
I'm sorry, I was supposed to speak in French, but I completely forgot.
In my opinion, you are right to think that this issue should be addressed from a jurisdictional point of view—that is to say from a political point of view, but we also have to consider natural borders.
That said, I think Ms. McFadyen has more experience in this area than I do.
