What I would indicate is that there is no target for 2050. There's no target set for Canada. The government has worked with provinces and territories, indigenous people, business, civil society, and all Canadians to develop a plan that has a variety of measures that are transparent. Our modelling in terms of how those measures contribute to meeting the target in 2030 is transparent, based on what was agreed to with provinces and territories at the first ministers meeting in December 2016.
An element of that agreement was a commitment to undertake a review of carbon pricing in 2020, and then again in 2022. It's those elements that are the basis for our work going forward with our counterparts in the provinces and territories, in consultation with business, indigenous groups, and civil society based on those transparent assumptions and the detailed information provided for all regulatory and other measures as part of the consultation process.
