Rigged Results: How Amazon's Search Engine Quietly Crushes Canadian Brands to Sell Its Own

When a Canadian shopper types a query into Amazon's search bar, they likely believe they are receiving an impartial list of relevant products. They are not. What they encounter is a carefully engineered ranking system — Amazon's proprietary A9 algorithm — designed not primarily to serve the shopper's interest, but to serve Amazon's bottom line. And for the thousands of independent Canadian sellers who depend on that search bar for their livelihoods, the consequences are devastating.

The Illusion of a Level Playing Field

Amazon has long marketed its marketplace as an open and democratic platform — a digital Main Street where any entrepreneur, from a family-run operation in Moncton to a craftsperson in Kelowna, can reach millions of customers. The pitch is seductive, and for a time, it worked. Canadian sellers poured resources into building their storefronts, optimising their listings, and accumulating the reviews that Amazon told them were the currency of success.

But the marketplace was never level. At the very moment a Canadian seller's product begins to gain traction — when reviews accumulate, when sales velocity climbs, when a product demonstrates genuine consumer demand — the algorithm takes notice. Not to reward the seller, but to study them. Amazon has faced extensive scrutiny, including from the U.S. House Judiciary Committee's antitrust subcommittee, for allegedly using third-party seller data to inform the development of its own competing private-label products. Once Amazon launches a competing product under one of its dozens of in-house brands, the original seller often finds their ranking inexplicably collapsed.

How the Algorithm Actually Works — and Who It Works For

A9, Amazon's search ranking system, weighs a complex matrix of signals: conversion rate, sales history, pricing competitiveness, and fulfilment method, among others. On paper, these criteria sound neutral. In practice, they function as a structural advantage for Amazon's own brands.

Consider fulfilment. Products shipped through Fulfilment by Amazon (FBA) receive a ranking boost — and Amazon's private-label products are, by definition, always fulfilled by Amazon. Consider pricing: Amazon can price its own brands at a loss or near-margin to undercut third-party competitors, then recover those losses through the fees it charges those very competitors for the privilege of selling on the platform. Consider the "Amazon's Choice" and "Best Seller" badges — coveted signals of credibility that Amazon awards according to its own opaque criteria, and which disproportionately appear on Amazon-owned or Amazon-affiliated listings.

The result is a search environment in which the referee is also a player — and has quietly rewritten the rules of the game.

Canadian Sellers Caught in the Crossfire

The human cost of this algorithmic manipulation is not abstract. Across Canada, small and medium-sized businesses have described the same arc: initial growth on the platform, followed by the sudden appearance of an Amazon-branded competitor, followed by a precipitous drop in search visibility that no amount of advertising spend could reverse.

For many of these sellers, Amazon was not merely one channel among many — it had become their primary or sole channel, a dependency Amazon's own onboarding process actively encouraged. When the algorithm turned against them, they had no fallback. Staff were let go. Inventory sat unsold. Years of brand-building evaporated because a single proprietary system decided, invisibly and without appeal, that an Amazon product deserved the top of the page instead.

This is not a market failure in the traditional sense. It is a market that was deliberately constructed to fail independent sellers at the moment of their greatest success.

The Regulatory Gap Amazon Exploits

Canada's Competition Bureau has broad authority to investigate anti-competitive conduct, but it has been slow to scrutinise Amazon's algorithmic practices with the same urgency that European regulators have brought to the issue. The European Commission opened formal proceedings against Amazon in 2020, specifically targeting the company's use of third-party seller data and its self-preferencing behaviour in search rankings. The EU's Digital Markets Act, which came into force in 2022, now explicitly prohibits large platform operators from ranking their own products more favourably than those of third-party sellers.

Canada has no equivalent framework. The 2024 amendments to the Competition Act represent meaningful progress — particularly the expanded merger review provisions and the new rules around drip pricing — but they do not yet squarely address algorithmic self-preferencing in digital marketplaces. Amazon, aware of this regulatory gap, continues to operate in Canada with a latitude that it would not be permitted in the European market.

This is not a technical oversight. It is a policy failure that demands political attention, and Canadian advocacy organisations, including the Canadian Federation of Independent Business, have begun to press for exactly that.

The Broader Stakes for Canadian Commerce

The A9 algorithm's preferencing of Amazon's own brands is not merely a competition law problem. It is a cultural and economic problem with distinctly Canadian dimensions. When an independent Canadian brand is buried beneath Amazon Basics or one of the company's dozens of private-label imprints — AmazonCommercial, Solimo, Pinzon, and scores of others — it is not simply a business that suffers. It is a community that loses a local employer, a tax base that loses a contributor, and a national economy that cedes ground to a foreign corporate giant that repatriates its profits south of the border.

Canadian consumers deserve to know that when they search for a product on Amazon, they are not seeing the best result. They are seeing the result Amazon has decided is most profitable for Amazon. The distinction matters enormously.

What You Can Do

Resisting algorithmic manipulation begins with awareness, but it cannot end there. Consumers who understand how Amazon's search engine operates have both the knowledge and the moral standing to take their business elsewhere. Canadian alternatives — from local retailers and regional e-commerce platforms to the growing ecosystem of direct-to-consumer Canadian brands — exist, thrive, and depend on exactly the kind of deliberate, values-driven purchasing decisions that Amazon's platform is engineered to pre-empt.

Search local. Buy direct. And the next time Amazon's search bar returns a tidy page of Amazon-branded results, remember: that page was not designed for you. It was designed for them.
