I would like to throw this question out to all four of you.
A lot of you have already given us some good advice on how we might vary the criteria currently applied to P3s. I'm just giving you an opportunity. The City of Edmonton said to do a P3 or you're not getting federal money for your LRT. I wonder if you could elaborate on whether or not you think there are additional criteria, which you might not have mentioned yet, that would be useful to include about the way P3s are being used at the federal level.
