Competition Bureau’s abuse of dominance litigation against Google continues 


March 4, 2026 – GATINEAU (Québec), Competition Bureau 


Acting Commissioner of Competition, Jeanne Pratt, issued a statement following the Competition Tribunal’s ruling to dismiss Google’s constitutional challenge. 


“We welcome the Competition Tribunal’s decision on this matter, which dismissed Google’s allegation that a constitutional right was breached. 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. We continue to stand by our investigative findings that, through its anti-competitive conduct, Google has been able to entrench its dominance, prevent rivals from competing, inhibit innovation, inflate advertising costs and reduce publishers’ revenues. The final decision in this matter, including any penalties, rests with the Competition Tribunal.”

In November 2024, the Bureau filed an application to sue Google for anti-competitive conduct in online advertising in Canada. Our investigation found that Google abused its dominant position as the largest provider of ad tech tools across the Canadian supply chain.

Competition Tribunal Rejects Google's Constitutional Challenge

On March 4, 2026, Acting Commissioner of Competition, Jeanne Pratt, announced that the Competition Tribunal dismissed Google's constitutional challenge regarding the Bureau's ongoing litigation against the company.

The Tribunal's ruling reinforces its authority to impose administrative monetary penalties aimed at ensuring compliance and deterring anti-competitive behavior. The Bureau's case against Google, which alleges abuse of dominance in the online advertising sector, continues to move forward.

In November 2024, the Competition Bureau initiated legal action against Google, citing its dominant position in ad tech tools across Canada as a barrier to competition. Following this, Google filed a constitutional question in February 2025, which the Bureau sought to strike in June 2025.
