How misinformation and partisan politics killed Canada's carbon tax: study findings

Canada's consumer carbon tax was repealed in 2025 after years of political opposition. New research in Climatic Change finds that voters' perceptions, not actual costs, drove the backlash. Conservative voters with similar fuel consumption to Liberal voters believed they were paying nearly $5,000 more per year in carbon taxes, and they continued to doubt rebates even after seeing their exact amounts. These findings matter beyond Canada. The policy was designed to return most revenue to households, and it did, but accurate information backfired in a hyper-partisan environment. Any future carbon pricing effort needs to make costs and rebates visible in ways that are harder to distort. For carbon market watchers, the lesson is about political sustainability. A well-designed price signal can still collapse if the public does not believe it is fair. The study is a useful case study for jurisdictions still considering carbon pricing.
