Canadian news publishers sue Anthropic in Ontario over alleged copyright infringement

According to a Canadian Press report published on CP24 on 19 October 2026, a coalition of publishers made up of Postmedia, Torstar, The Globe and Mail and The Canadian Press sued AI company Anthropic in Ontario. The claim was filed on 6 October 2026 and first reported by Cartt.ca.

• The publishers allege that Anthropic infringed their copyright and was unjustly enriched by using their content to develop the Claude model.
• According to the claim, Anthropic scrapes large amounts of text and keeps doing so when it answers user prompts.
• The publishers also allege breaches of their websites' terms of service and the circumvention of technical measures meant to restrict copying.
• Anthropic did not respond to a request for comment; the allegations have not been proven in court.

Why it matters

The same publishers, together with CBC/Radio-Canada, sued OpenAI in 2024, and that case has not been settled. The report adds that publishers want the federal government to state its position on AI systems' use of copyrighted material, and say its national AI strategy left that question open. The case shows that AI companies can face legal claims not only over training data but also over ongoing content collection when answering user prompts. Turkish companies worried about unauthorised copying of their content may want to review their website terms of use and bot access rules.
