We have to distinguish, first of all, between the ability of the federal government to ask for reports.... For example, we know very accurately what the greenhouse gases are that are being emitted from the oil sands. Through CEPA we know about toxic materials across the country. We have the right to ask for that. We also have the right to regulate certain of those things.
There is sometimes a dispute as to whether you use the tax system or whether you use peace, order, and good government. All I'm saying is that we already, on a variety of environmental files, have a way of working with the provinces. Equivalency agreements would be an example.
