If there are, broadly, six big slices of carbon emissions in Canada—electricity generation, upstream oil and gas, industry, vehicles, residential, agriculture and forestry—are there any obvious places where a carbon tax is more appropriate in one of those sectors than in another, yet in another one cap and trade might work? Are there obvious divisions? If you're going to have a mix and match system, which you've talked about, or a suite of instruments, are there places where you'd have one in one case and one for another?
