As I mentioned just now, the incidence of denial of access because of cabinet confidence is extremely rare. I wouldn't say this is by any means a trend--rare means it happens exceptionally. And it is when documents go before cabinet; then, cabinet has that right, in the sense that what's in discussion in cabinet is protected.
Right now, based on the information we had, I don't have any particular concern that what we have in front of us involves any kind of warning in any way. It's up to the government, in their policy choices in the future, whether they want to go to more or fewer fiscal policies to address environmental issues. That's a choice of the government, and we would come across it when we looked at it.
More generally comparing the U.S. and Canadian experience, as I mentioned earlier, the nature of the Canadian confederation is that when, under the trust, the provinces receive it, there are no legal obligations or conditions attached to the trust funds giving the province an obligation to report back. There's not a legal obligation for the provinces to do so, so there's not a way for Ottawa to measure their performance concerning how the funds are being used.
