High food prices are a major threat to food security for many Canadians. (Ian Mutto/Flickr), CC BY-SA
Unfortunately, consensus on why food price are so high is in short supply. Explanations given in reports like Canada’s Food Price Report and the news media range widely, from the war in Ukraine to supply chain issues to the carbon tax.
Each year it seems the key drivers change, and if the growing consumer boycott of Loblaw’s is any indication, consumers want better answers.
So, we completed a rigorous analysis of the most prominent reports that shape the narratives around food prices in Canada, including twelve years of Canada’s Food Price Reports and 39 reports from Statistics Canada. Our findings, which are peer reviewed and soon to be published in Canadian Food Studies, were both insightful and concerning.
Lacking scientific rigour
Our analysis found that most claims about food prices in these reports lack scientific rigour. Nearly two-thirds of the explanations for price changes given are not backed by evidence. Arguments about the causes of food inflation are frequently incomplete, neglecting to connect the dots between cause and effect.
For instance, reports may identify the influence of unfavourable weather, climate change or changing retail demand, but fail to elaborate how these translate into actual price increases at the till.
British philosopher Stephen E. Toulmin published a simple approach for evaluating the quality of scientific arguments in 1958. In a nutshell, for a scientific argument to be complete, it needs to have three components: a claim, verifiable observations or data that provide grounds for that claim, and an explicit theory or assumption that links the data logically to the claim.
For scientific arguments to be rigorous, they should also back up the strength of their assumptions and qualify their claims by exploring reasonable counterarguments. However, most of the arguments in these reports fall short of this, failing even to provide basic evidence in support of their claims.
These reports are not scientific publications, but rather qualify as “grey literature” — information produced outside traditional academic publishing channels.
Nevertheless, they are published under the logos of academic institutions and government agencies. Given their prominence in Canadian media and policy, we believe it is important for the public to know that the arguments presented in these reports do not live up to scientific standards.
Overlooking key issues
While the reports do identify potential drivers of food prices, they have some noteworthy gaps.
While extreme weather events and climate change are sometimes offered as abstract reasons for food price increases, some major environmental issues, like biodiversity loss and collapsing fish stocks, do not appear in reports, despite a widespread understanding that they will impact food price and availability.
These reports also rarely consider the decisions that grocers and other private sector entities have on food prices. Increased consolidation and concentration in the grocery sector is a structural issue that deserves scrutiny.
The bread price-fixing scandal a few years ago showed how a lack of competition enables price manipulation and hurts consumers. Canada’s Competition Bureau recently announced they are launching an investigation into the owners of Loblaws and Sobeys for alleged anti-competitive conduct.
In the United States, there is also strong evidence that the private sector has been profiteering on supply chain issues and inflation. The U.S. Federal Trade Commission likewise recently found that big grocers used the pandemic as a smokescreen to pad their profits at the public’s expense.
With grocer profits expanding in Canada, too, it is fair to ask tough questions about how much grocers’ decisions are contributing to the pain at the till.
In our analysis, only three per cent of the over 200 explanations for food price changes point to grocer actions or other agency in the private sector as driving price increases. This reflects a tendency to portray food prices as erratic and overwhelmingly opaque.
Other issues — such as the over-reliance on fossil fuels across the supply chain — also go unmentioned.
A new approach is needed
Without rigorous and transparent analysis, we’re left with an incomplete picture of why food is so expensive and what we can do about it.
What we need is a new approach. Food is a human right, but a unique one in that we rely on the private sector to provision it. We should expect a higher standard than with other consumer goods, and the private sector has arguably not earned the benefit of the doubt given their history of price fixing.
One positive step towards generating trustworthy evidence about food prices would be to incorporate transparency measures into the code of conduct the Canadian government is developing with grocers. This could include third-party audits, open data-sharing and a clear breakdown of what’s driving price changes — from the farm to the shelf.
Peer review of research is a critical aspect of responsible science. In our paper, we highlight the process that the Canadian Science Advisory Secretariat provides for federal fisheries science, as one possible model for government-based food price reports.
For something as essential as food, Canadians deserve the full story. For decades, policy and markets have been designed to keep food cheap, but at the expense of workers and the environment.
If food prices are rising because they are starting to reflect the true social and ecological costs of production, we will need to enter a broader conversation about economic and livelihood reform to ensure that everyone can afford food. But without a clear picture of the actual drivers, we lack the necessary information for developing policies that protect the rights and well-being of Canadians.

Capital in the Twenty-First Century
by Thomas Piketty. (Translated by Arthur Goldhammer)
In Capital in the Twenty-First Century, Thomas Piketty analyzes a unique collection of data from twenty countries, ranging as far back as the eighteenth century, to uncover key economic and social patterns. But economic trends are not acts of God. Political action has curbed dangerous inequalities in the past, says Thomas Piketty, and may do so again. A work of extraordinary ambition, originality, and rigor, Capital in the Twenty-First Century reorients our understanding of economic history and confronts us with sobering lessons for today. His findings will transform debate and set the agenda for the next generation of thought about wealth and inequality.

Nature's Fortune: How Business and Society Thrive by Investing in Nature
by Mark R. Tercek and Jonathan S. Adams.
What is nature worth? The answer to this question—which traditionally has been framed in environmental terms—is revolutionizing the way we do business. In Nature’s Fortune, Mark Tercek, CEO of The Nature Conservancy and former investment banker, and science writer Jonathan Adams argue that nature is not only the foundation of human well-being, but also the smartest commercial investment any business or government can make. The forests, floodplains, and oyster reefs often seen simply as raw materials or as obstacles to be cleared in the name of progress are, in fact as important to our future prosperity as technology or law or business innovation. Nature’s Fortune offers an essential guide to the world’s economic—and environmental—well-being.

Beyond Outrage: What has gone wrong with our economy and our democracy, and how to fix it -- by Robert B. Reich
In this timely book, Robert B. Reich argues that nothing good happens in Washington unless citizens are energized and organized to make sure Washington acts in the public good. The first step is to see the big picture. Beyond Outrage connects the dots, showing why the increasing share of income and wealth going to the top has hobbled jobs and growth for everyone else, undermining our democracy; caused Americans to become increasingly cynical about public life; and turned many Americans against one another. He also explains why the proposals of the “regressive right” are dead wrong and provides a clear roadmap of what must be done instead. Here’s a plan for action for everyone who cares about the future of America.

This Changes Everything: Occupy Wall Street and the 99% Movement
by Sarah van Gelder and staff of YES! Magazine.
This Changes Everything shows how the Occupy movement is shifting the way people view themselves and the world, the kind of society they believe is possible, and their own involvement in creating a society that works for the 99% rather than just the 1%. Attempts to pigeonhole this decentralized, fast-evolving movement have led to confusion and misperception. In this volume, the editors of YES! Magazine bring together voices from inside and outside the protests to convey the issues, possibilities, and personalities associated with the Occupy Wall Street movement. This book features contributions from Naomi Klein, David Korten, Rebecca Solnit, Ralph Nader, and others, as well as Occupy activists who were there from the beginning.
