Canadian publishers have accused OpenAI of breaching copyright law by using millions of articles to train ChatGPT, launching a lawsuit in Ontario Superior Court. Plaintiffs include Torstar, Postmedia, The Globe and Mail, CBC/Radio-Canada, and The Canadian Press, which allege unauthorized use of more than ten million works since 2015.
They seek damages up to $20,000 per work, plus profits and an injunction. OpenAI contends the case belongs under U.S. copyright law, arguing its activities occur outside Ontario. The hearing begins today, marking Canada’s first major AI copyright suit.
