Madam Chair, simply put, Ontario has put in place an approach to carbon pricing, and that already exists. The approach we are proposing, the federal backstop, would not be applicable in the province of Ontario since it currently has an approach to pricing carbon. That would only apply to those jurisdictions that do not currently have a price on carbon, and that of course is the small minority of Canadians not already in that jurisdiction.
