On June 5, 2026, Canada's Competition Tribunal ordered Google to pay more than C$358,000 in costs to the Competition Commissioner — a relatively modest sum by the standards of Big Tech litigation, but one that closes the last major procedural escape route before a liability hearing that could force the company to divest two of its most strategically vital advertising products.
The costs award settles the bill from Google's failed constitutional challenge, a legal gambit that sought to neutralize the Bureau's penalty arsenal before a single finding of liability had been made. Its dismissal in March was consequential. Its costs order in June is definitive: the path now runs directly to the merits.
What Google Was Attempting
To understand the stakes, start with the money. When the Competition Bureau filed its abuse-of-dominance case against Google on November 28, 2024 under section 79 of the Competition Act, it brought with it a statutory penalty formula that — applied to Google's global scale — produced a theoretical ceiling of C$91 billion. Under the Act, administrative monetary penalties (AMPs) may equal either three times the benefit derived from anti-competitive conduct or three percent of worldwide gross revenues, whichever is larger.
Google's legal team argued that an AMP of that magnitude would constitute a "true penal consequence" — language borrowed from constitutional criminal law — which would trigger Charter of Rights and Freedoms protections normally reserved for accused persons in criminal proceedings. The logic was structural: if a sanction is punitive enough in effect, the constitutional constraints on punishment must follow, regardless of how legislators label the tool.
The argument was not frivolous. Canada's Supreme Court has recognized that regulatory penalties can cross into criminal territory if they are primarily punitive in character and effect. Google's lawyers were threading a genuine doctrinal needle.
But on March 4, 2026, Justice Andrew D. Little of the Competition Tribunal rejected it. The tribunal held that the AMPs under the Competition Act are regulatory rather than penal in purpose — they exist to promote compliance and deter anti-competitive conduct, not to punish wrongdoers — and therefore the constitutional protections Google invoked do not attach. The challenge was dismissed, and both parties were directed to submit arguments on cost allocation. Three months later, the tribunal issued its answer: C$277,600 in expert fees, C$54,000 in legal fees, and C$26,600 in transcripts and printing, all payable by Google.
Acting Commissioner Jeanne Pratt welcomed the result with characteristic directness: "The Tribunal's decision reinforces its clear authority to order administrative monetary penalties to promote compliance and deter anti-competitive behaviour. Our case against Google continues."
The Underlying Abuse-of-Dominance Case
The main proceeding, when the liability hearing begins, will be considerably more consequential than the procedural sideshow it took to clear away.
The Bureau's allegations describe a vertically integrated chokehold across the online advertising supply chain. According to the Bureau's November 2024 filing, Google controls an estimated 90 percent of the publisher ad server market, approximately 70 percent of advertiser networks, 60 percent of demand-side platforms, and 50 percent of ad exchanges in Canada. Those positions, the Bureau contends, were not merely accumulated through competition on the merits — they were actively reinforced through a series of deliberate foreclosure strategies.
The specific conduct alleged includes: making Google's advertiser network available exclusively through its own ad exchange, requiring publishers to use its ad server (DoubleClick for Publishers, or DFP) to access real-time bids from that exchange, and distorting auction dynamics by giving its own exchange preferential access to ad inventory — including, in some instances, deliberately accepting negative margins to disadvantage competing exchanges.
The remedies sought go further than a fine. The Bureau is asking the tribunal to order the forced sale of DFP and AdX outright. If granted, Google would be required to divest the two products that form the spine of its advertising infrastructure and generate the bulk of its non-search revenue.
Steelmanning the Defense
Before reaching a verdict on the merits of forced divestiture, the strongest version of Google's case deserves fair consideration. Vertical integration across the ad tech stack is not inherently anti-competitive; companies that build end-to-end tools may do so because integrated products lower transaction costs and improve performance for both advertisers and publishers. Google has maintained consistently that its market position reflects superior product quality and that advertisers and publishers retain meaningful alternatives.
That argument is not without force. Forced structural remedies carry real costs: divestiture disrupts engineering teams, may degrade the quality of products that have been co-developed over years, and creates regulatory uncertainty that could chill investment across the broader ad tech sector. The European Commission, when it settled its parallel ad tech investigation, ultimately pursued behavioral rather than structural remedies — a signal that conduct-based interventions may accomplish competitive objectives without the collateral damage of a break-up.
The difference, however, lies in what the Bureau's investigation documented. Taking negative margins specifically to undercut rival exchanges is not a by-product of efficiency — it is a deliberate foreclosure strategy that cannot be explained by any neutral account of competitive behavior. The constitutional challenge, by seeking to cap penalty exposure before liability was established, implicitly acknowledged that the conduct the Bureau documented was serious enough to warrant advance legal protection.
Three Jurisdictions, One Architecture
Canada is not pursuing this in isolation. A US federal district court found Google liable for monopolizing the ad tech market in November 2024, with remedies proceedings — including potential AdX divestiture — now underway. The European Commission has also examined Google's ad tech conduct under the Digital Markets Act framework. Canada's case, if it proceeds to a liability finding, would add a third major jurisdiction demanding structural reform of the same underlying product architecture.
For publishers who have seen revenue eroded by opaque auction dynamics, for smaller ad tech firms unable to access inventory on equal terms, and for advertisers uncertain whether competition is real or simulated, the coordinated international pressure represents something larger than any single regulatory proceeding. It is a test of whether antitrust enforcement — applied simultaneously across multiple sovereign jurisdictions — can actually reshape a dominant platform's commercial structure.
The tribunal's June 5 costs order is, in the scheme of things, a small number. But it closes the door on procedural delay and opens the one that leads to the only question that has ever mattered in this case: did Google abuse its dominance, and if so, what must it give up?
