As prime minister Justin Trudeau trails in polls, opposition seek to persuade voters environmental policy is a burden

Mass hunger and malnutrition. A looming nuclear winter. An existential threat to the Canadian way of life. For months, the country’s Conservative leader Pierre Poilievre has issued dire and increasingly apocalyptic warnings about the future. The culprit? A federal carbon levy meant to curb greenhouse gas emissions.

In the House of Commons this month, the Tory leader said there was only one way to avoid the devastating crisis: embattled prime minister Justin Trudeau must “call a ‘carbon tax’ election”.

Hailed as a global model of progressive environmental policy, Canada’s carbon tax has reduced emissions and put money in the pockets of Canadians. The levy, endorsed by conservative and progressive economists, has survived multiple federal elections and a supreme court challenge. But this time, a persistent cost-of-living crisis and a pugnacious Conservative leader running on a populist message have thrust the country’s carbon tax once more into the spotlight, calling into question whether it will survive another national vote.
