Canada's Competition Bureau says it has opened an antitrust investigation into Amazon to determine if it hurts consumers and competition
Annie Palmer / CNBC :
Context & Ripple Effects
Canada's Competition Bureau has been here before with Big Tech — it closed out its earlier Google antitrust probe without action in 2016 — but its posture has hardened sharply since. By early 2024 the watchdog had expanded a four-year Google ad-tech probe toward predatory pricing questions, and by November it was suing Google outright and demanding divestiture of two ad tools.
Opening an Amazon investigation slots the retail giant into that same escalation pipeline, and mirrors what other regulators are doing: the UK's CMA had already launched its own probe into whether Amazon favors its retail arm and Prime-linked sellers.
First-order effects
- Amazon's Canadian marketplace practices — how it treats third-party sellers relative to its own retail business — come under formal regulatory examination, putting its seller policies and self-preferencing under documented scrutiny for the first time in Canada.
Second-order effects
- With the CMA running a parallel Amazon investigation in the UK, the Bureau's move adds a second major jurisdiction examining the same self-preferencing question, raising the compliance and disclosure burden on Amazon across its largest English-speaking markets.
Third-order effects
- If Amazon follows the path the Bureau laid out with Google — probe, expansion, then a suit seeking structural remedies like forced asset sales — platform regulators would be signaling that behavioral fixes no longer cap their ambitions, with marketplace separation on the table as an endgame.
The trend: Competition authorities in Canada and the UK are converging on big-platform marketplaces as targets, moving from exploratory probes to litigation backed by structural remedies.
