Canadian news publishers sue Anthropic in Ontario court, alleging copyright infringement over the training of Claude
Postmedia, Torstar, The Globe and Mail and The Canadian Press filed a copyright lawsuit against Anthropic in an Ontario court, Global News, CBC News, The Globe and Mail, Radio-Canada and La Presse reported on 19 October. The publishers allege that Anthropic used their content to train its Claude chatbot without a licence, breached website terms of use and circumvented technological protection measures meant to restrict copying. The claim lists copyright infringement, breach of contract and unjust enrichment. The publishers seek statutory damages of up to $20,000 per infringed work and injunctions. Anthropic had not responded to requests for comment in the reports reviewed. The Canadian Press noted a similar suit against OpenAI was filed by a coalition of Canadian publishers in November 2024.
Canadian copyright law has not been tested on whether training a chatbot on news articles is infringement, and statutory damages per work could multiply quickly across a large archive. The case also asks whether paywalls and website terms can be enforced against automated collection, which affects how every publisher licenses its journalism.
If you read or work for Canadian news outlets, the case may shape whether licensing deals with AI companies become the norm. For general readers, nothing changes in how the chatbots work today, and a ruling is unlikely for a long time.
The publishers argue their reporting is costly to produce, protected by copyright and terms of use, and taken without payment, and they want damages and injunctions to force licensing. Their earlier suit against OpenAI follows the same logic.
AI developers have argued in other jurisdictions that training on public text is a transformative use that does not substitute for the original. Anthropic had not responded in the reports reviewed, and the allegations remain unproven in court.
Confirmed: the filing, the four named plaintiffs and the relief sought. Not confirmed: the date of any hearing, Anthropic's defence, and whether more publishers join. Watch for Anthropic's statement of defence, any jurisdiction challenge like the one in the OpenAI case and talk of licensing deals.
