Mr. Plourde, I have a quick question for you.
In terms of carbon emissions, as we transition over the next 10, 15, 20 years, do you believe we will have better results if we try to impose a moderate price on carbon? That's recognizing, as I do as well as everybody else, that companies need to be able to be profitable and to reinvest in themselves. Industry always drives innovation—absolutely.
Do you believe that the companies will be able to further their innovation quicker by a moderate price on carbon and then the government in turn subsidizing innovation, or just straight subsidy on innovation? Which would be the most effective route?
