I want to thank both ministers again for being here because I've been in that seat before, and it's sometimes not a pleasant place to be. I found that it's sometimes easier simply to answer the questions. If it's a yes-or-no question, you either say yes or no, and then the committee has the answer it needs or that it has asked.
On five occasions now, Minister McKenna, you have been asked, “Do you know how much your national carbon tax backstop will reduce greenhouse gas emissions?” We still don't have an answer. I know you've found ways around the question, but we really need to know. Do you and those in your department know how much that carbon tax will actually reduce our greenhouse gas emissions in Canada?
Yes or no?
