At that time, I don't think we set them at a provincial level, but I could go back and look. The analysis rolled out to certain provincial reductions. Obviously it shouldn't come as any surprise to you where the real reductions occur. They occur in the electricity sector and in the oil and gas sector, as that's where they're most cost effective. Provincially you get more cuts in Alberta than you do in Quebec. There is a certain logic there.
The main instrument we used at that time was a pricing mechanism, which we called an atmospheric user charge. Whether it's carbon trading or a carbon tax, it's essentially a metaphor for putting a price on carbon. We applied a price in the modelling effort that showed in fact that through regulation and pricing mechanisms, which were not in any way destructive to the economy, we could achieve our objectives.
At that time, we had no idea that minus 6% would be the number coming out of Kyoto. That was an absolute coincidence and not planned at all.
