British Columbia sues OpenAI over Tumbler Ridge shooting, seeking damages and safety changes
British Columbia has sued OpenAI and CEO Sam Altman in U.S. federal court in California, seeking recovery of public costs after the school shooting and an order changing how ChatGPT handles conversations that could lead to violence. Multiple outlets confirmed the filing; the province's allegations have not been adjudicated.
Why it matters
The case puts before a court whether an AI provider must alert law enforcement after detecting a potential violent threat, how it should prevent banned users from returning, and whether governments can recover public-response costs. The outcome could shape AI-safety and product-liability policy in Canada and the United States.
Full report
Reuters, the Financial Times and The Wall Street Journal independently reported that British Columbia filed the lawsuit against OpenAI and Sam Altman in San Francisco federal court on September 21. The filing, defendants and principal remedies are confirmed; causation, negligence and product-liability claims in the complaint remain allegations and have not been decided by a court.
The complaint seeks damages for costs the province says it has incurred and will incur, including a replacement school, mental-health care and other public expenses. It also asks for a court order changing how OpenAI handles ChatGPT conversations that could lead to violence. The amount recoverable and availability of the requested remedies remain for the litigation process.
The province alleges that OpenAI's safety team flagged the shooter's account after gun-violence conversations and that staff recommended contacting police, but law enforcement was not alerted. It further alleges that after the account was disabled, the user obtained another account. These are complaint allegations and cited materials, not facts established by a judgment.
The February 10, 2026 attack in Tumbler Ridge killed eight victims; the shooter then died by suicide, and more than 25 people were injured. An OpenAI spokesperson called the attack an unspeakable tragedy and said the company remains committed to working with government and law-enforcement officials and to advancing safety work. OpenAI has previously said it reports conversations when they show an imminent and credible risk of harm to others.
