Canada’s costly climate gamble on food needs to end
For years, Canadians were told that catastrophic climate scenarios justified virtually any policy imposed in the name of emissions reductions. In agriculture and food, this translated into mounting costs across the supply chain, escalating industrial carbon pricing, and a policy environment increasingly disconnected from affordability and competitiveness.
Now, quietly, the scientific conversation is evolving.
A recent paper published in Geoscientific Model Development, tied directly to the next generation of UN-backed climate modeling for the IPCC’s upcoming assessment cycle, suggests that some of the most extreme warming scenarios used for years are no longer considered plausible. The infamous SSP5-8.5 pathway, often portrayed publicly as a “business-as-usual” future, assumed an explosion in coal consumption, extraordinarily high fossil fuel dependence, and emissions trajectories that increasingly diverged from economic and technological realities.
In plain English: some of the world’s leading climate scientists are now acknowledging that humanity is unlikely to follow the catastrophic path that dominated climate communication for much of the last decade.
Yet Canadian policy, especially in agri-food, still behaves as though we are one harvest away from Mad Max.
This matters because few sectors absorb policy costs more directly than food.
Even after Ottawa effectively zeroed out the consumer carbon levy on fuels in 2025, the industrial carbon pricing regime remains firmly in place and continues to rise, reaching $110 per tonne this year. These costs ripple through virtually every segment of the food economy: fertilizer production, trucking, warehousing, refrigeration, food processing, packaging, greenhouse operations, grain drying, and cold-chain logistics.
Food systems are extraordinarily energy intensive. Unlike many sectors, food has no pause button. Products perish. Refrigeration cannot stop. Trucks must move. Grain must dry. Livestock must eat.
And while government officials often insist the carbon price has only a “minimal” effect on grocery bills, that argument misses the broader economic picture entirely. The real issue is not simply retail pass-through. It is competitiveness.
Canada’s agri-food sector competes globally. When domestic costs rise faster than those faced by competitors in the United States or elsewhere, investment shifts. Processing capacity weakens. Domestic production becomes less attractive. Imports increase. Over time, consumers pay the price through weaker food sovereignty and higher structural costs.
This is not theoretical anymore.
Canadians are already visiting grocery stores more frequently in search of deals. Restaurant bankruptcies are accelerating. Food affordability remains the number one concern for households according to repeated national surveys conducted by Dalhousie University’s Agri-Food Analytics Lab. Families are adapting, trading down, and increasingly prioritizing price over virtually every other food value.
Meanwhile, policymakers continue layering costs onto the supply chain as though affordability were a secondary concern.
The irony is that the climate science itself is becoming more nuanced while public policy remains rigid.
To be clear, none of this means climate change is fake, harmless, or irrelevant to agriculture. Canadian farmers still face drought risks, floods, extreme weather volatility, and shifting growing conditions. Agriculture has always been vulnerable to nature. It always will be.

But policy should be proportional to realistic risks, not permanently anchored to worst-case scenarios that scientists themselves are now reassessing.
Canada’s food strategy needs recalibration.
Instead of obsessing over punitive cost mechanisms, Ottawa should focus on resilience and productivity: modernizing transportation infrastructure, investing in irrigation and water systems, accelerating precision agriculture, supporting genetics research, strengthening domestic processing capacity, improving trade logistics, and encouraging technological innovation throughout the food chain.
Innovation reduces emissions. Efficiency reduces waste. Productivity strengthens food security.
Punishing domestic production does not.
The danger now is not climate denial. It is policy inertia.
Governments built much of today’s climate framework around assumptions that are quietly being revised by the scientific community itself. Yet admitting that some assumptions may have been overstated has become politically difficult because too many institutions, activists, and even media organizations spent years presenting worst-case scenarios as inevitabilities rather than possibilities.
The result is a dangerous disconnect between economic reality and policy ambition.
Canada needs climate policy rooted in pragmatism, not ideology. Especially in food.
Because in the end, no country can claim to care about sustainability while simultaneously making food less affordable, weakening domestic production, and eroding its own supply chains.
