Madam Speaker, I heard the same thing, that provinces could reduce carbon emissions without a price. When I look at the Auditor General's work in Ontario, actually it is not always the case that this happens.
If we truly are serious about taking the most market-based mechanism we can, relying upon the market not picking winners, that means a price on pollution. It allows different technologies to develop, and we make sure the social costs and the negative externality, if we are talking economics and financial language, are internalized in the cost of the good at the point of purchase. That is what a price on pollution does. It is a conservative idea going back to Ronald Coase, who was not a liberal. That is fundamentally the best way to tackle climate change.
