# Canada's largest news publishers (Postmedia, Torstar, Globe and Mail, Canadian Press) sue Anthropic in Ontario over Claude training and ongoing scraping

On Oct 6, 2026 a coalition of Canadian news publishers including Postmedia, Torstar, The Globe and Mail and The Canadian Press sued Anthropic in an Ontario court, alleging copyright infringement, breach of website terms, circumvention of technological protection measures and unjust enrichment from using their journalism to build Claude. The suit, first reported by Cartt, became public on Oct 19.

## Key facts
- Filed: Oct 6, 2026, Ontario court (statement of claim; first reported by Cartt.ca, then Global News and blogTO on Oct 19)
- Plaintiffs include Postmedia, Torstar, The Globe and Mail and The Canadian Press (blogTO: 'include', so the list may be longer)
- Claims: copyright infringement in developing Claude; breach of the sites' terms of service; circumvention of technological protection measures; unjust enrichment; ongoing scraping of their sites in response to user prompts, not only for training
- Quoted from the claim: Anthropic 'has capitalized on the commercial success of its AI models' ... 'without obtaining a valid licence from any of the News Media Companies'
- Remedies sought: not stated in the coverage we read. Anthropic had not commented; the allegations are unproven
- Context: the same publishers plus CBC/Radio-Canada sued OpenAI in Ontario in 2024; that case is not settled (Global News)

## What happened

Canadian publishers that have been in court with OpenAI since 2024 opened a second front against Anthropic. Besides training, the claim
targets Claude's live retrieval of their articles when users ask questions, and says Anthropic got around measures meant to block
copying. Coverage is based on the statement of claim; no court date has been reported.

## Why it matters

It adds a Canadian case to Anthropic's copyright exposure weeks before its planned IPO, and it attacks retrieval at answer time, which
licensing deals and fair-use defences built around training do not necessarily cover.
