That's a very important question.
A number of provinces opted to bring in carbon pricing on their own and have begun taxing carbon because they understand the importance of charging for carbon pollution and internalizing those costs.
Everyone who has spoken today, particularly those who represent business, know that production costs exist. Carbon is one of those costs. No one can ignore that reality or the real consequences of carbon pollution, unless they're living in fantasyland. We have to internalize the costs of polluting — hence the carbon tax.
The federal government has introduced the carbon tax in provinces and territories that opted not to have their own systems. That resulted in some consistency, and we now have a system that works for the entire Canadian federation. The Supreme Court of Canada ruled in the federal government's favour, determining that the act could be implemented.
The elimination of that carbon pricing system would put some provinces at a disadvantage as compared with others. The provinces that had made the wrong choice — allowing polluters to go unchecked and keeping pollution free — would have the advantage over those provinces that had made the right choice — putting a price on carbon. Obviously, that's not the way to go.
Moreover, that's not the way to do things from an international standpoint. The focus is shifting to taxing imports at the border, so that countries whose production costs don't reflect carbon pricing pay for pollution.
In short, eliminating carbon pricing would fly in the face of common sense, not to mention GHG reduction efforts around the world.
