British Columbia filed a lawsuit against OpenAI in California, alleging the company failed to report threats made on ChatGPT before the mass shooting at Tumbler Ridge Secondary School on February 10, 2026, which killed eight people and injured 27. Internal reports show OpenAI's safety teams flagged the perpetrator's violent prompts months earlier, but leadership did not notify the RCMP or local authorities. The province seeks accountability and support for community rebuilding, including a new school.
