Thank you, Mr. Chairman.
Dr. Drouin, you are asking much of the federal government, and this is normal, because air pollution is a cross-border problem.
Bill C-30 removes the six greenhouse gases that the Liberal government had included in the list of toxic substances, and places them on another list that may not be clearly defined at this time.
Do you think that this transfer has taken away the federal government's legal and constitutional authority to regulate greenhouse gases? Have you had time to think about this?
