I'm not a constitutional authority, so I'm taking you at your word.
Again, I cannot see any path forward towards compliance with any target below 2006 levels ranging between 20% and above by 2020 without substantial government spending. There are two reasons, and they're quite different.
One is that we often talk about the great opportunities, such as large hydro, east-west transmission lines, transit, and others, but the lion's share of large projects that we all know need to proceed require--to be delivered and in place by 2020--at least $90 billion, and maybe $125 billion, in capital investment to be in place before 2012. Most of the provinces have debt loads that are too high to be able to afford to raise that amount of cash, even on a return-on-investment basis, without federal participation.
The second thing that's really important is that anything we do is going to increase energy prices, which puts the 1.3 million low-income families in Canada in distress. It's going to cost at least $5 billion to pay the full costs of renovating their houses to make them more efficient. You can't move without those cash components—
