Canadian publishers sue Anthropic over copyright in Claude training

Postmedia, Torstar, The Globe and Mail and The Canadian Press filed a lawsuit against Anthropic in an Ontario court on October 6. The publishers allege the company used their content to train Claude without a licence and circumvented copy protections. The same publishers and CBC sued OpenAI in 2024, and that case remains unresolved.
