In this chapter, we first consider how populism fits into the climate change debate and provide a brief overview of the environmental situation in Canada. We discuss the emergence of a new political divide in relation to climate change. We analyze the positioning of the main parties and the carbon tax as a partisan issue. Lastly, we look at the Canadian public opinion toward environmental issues. Green taxation and energy are used as wedged issues. They are also sparking a debate about individual lifestyles. What habits do we need to question? What individual and collective behaviors do we need to change? Who should pay for the transition to a low-carbon society? At what pace should these changes take place? With climate change, the environment has become an increasingly divisive subject in Canadian politics. The Trudeau government’s introduction of a carbon tax was successfully criticized by Pierre Poilievre, so much so that it led to the resignation of the Liberal leader. This policy was then abandoned by his successor, Mark Carney. This tax, seen as a coercive measure to combat climate change, became the first victim of the populist surge.
