There has certainly been an evolution in the rationale for this. This idea of public-private partnerships bringing new money was in large part seen as a way also of holding public investment off the government books. It was a bit of an accounting mirage that was used in the United Kingdom. These projects, I think especially in Canada, are being counted on the books, and that's the correct way to do it.
In terms of new approaches to achieving value for money, I think we need to have all of the information out in the public realm so that the public can be meaningfully engaged in the discussions around the types of projects that are taking place in their communities. We've had numerous experiences where sufficient information has been considered commercially sensitive during the bidding process. This might be okay for some types of projects, but when we're talking about highly public infrastructure, when we're talking about the transit lines or the hospitals, it's critical that this information is in the public domain. That really contributes to achieving value for money when the communities can see there's a transparency and that the projects are going to meet the needs they see for their communities.
