British Columbia sues OpenAI and Sam Altman over ChatGPT and the Tumbler Ridge school shooting
On Sept 21, 2026 the Canadian province of British Columbia sued OpenAI and CEO Sam Altman in US federal court in San Francisco, alleging negligence for not alerting police after OpenAI's safety team flagged the ChatGPT activity of the person who killed eight people in Tumbler Ridge, B.C., on Feb 10, 2026. It is the first suit of its kind by a government; B.C. seeks costs and a court-ordered overhaul of how OpenAI handles violent threats in conversations.

What happened
British Columbia's government filed suit in San Francisco against OpenAI and Altman over the February 2026 Tumbler Ridge shooting. The claim centres on OpenAI's decision not to notify police after its internal safety team flagged the shooter's ChatGPT conversations about gun violence and banned the account in mid-2025. Tom's Hardware reports the suit also seeks money toward a new school and frames the claim as "aiding and abetting".
Why it matters
It moves liability for chatbot conversations from private plaintiffs to a government, and targets a lab's duty to report credible threats. It was filed in the same week that OpenAI's agent incidents dominated coverage, adding to legal pressure on the company (see the Florida AG motion).
Caveat: the WSJ original is paywalled; details come from Al Jazeera, Tom's Hardware and the National Observer. The "aiding and abetting" framing and the new-school request come from Tom's Hardware's headline and were not checked against the complaint.
