For years, Conservative Leader Pierre Poilievre has been framing the federal race as a “carbon tax election.” But then Mark Carney became the Liberal Leader and Prime Minister and “axed the tax” for him, setting the consumer carbon price to zero.

Now, Poilievre is targeting another federal carbon tax – the one on the industry’s largest emitters. It’s part of a broader shift in this election toward energy sovereignty. Against the backdrop of U.S. President Donald Trump’s ongoing threats to Canada’s economy, there’s been a surge in public and political support for domestic oil and gas projects.

Today, The Globe’s Adam Radwanski, a columnist who covers climate policy, is on the show. He’ll walk us through the ongoing political fight over carbon pricing, why we’re suddenly seeing more support for pipelines, and the cost of slowing Canada’s efforts against climate change.
