I think the science and the information continue to evolve and change, and rapidly change. There wasn't as much of a sense of urgency to respond to the climate crisis in 2019 as there is now.
You might recall that there was a lot of court action surrounding the Greenhouse Gas Pollution Pricing Act. We had the premiers of many provinces, Conservative premiers primarily, asking the question, “Is this constitutional?” I actually need to thank those premiers, because they managed to do something that 40 years of environmentalism couldn't do. In a matter of a year, they got environmental degradation declared as an “existential threat” to humanity by the Supreme Court. We owe them a debt of gratitude there, I think.
