British Columbia Sues OpenAI Over Tumbler Ridge Shooting Links
British Columbia has filed a lawsuit against OpenAI in a California court, alleging the company failed to alert authorities after its own safety team flagged ChatGPT activity connected to the Tumbler Ridge mass shooting months before the attack. The legal action, initiated on Monday, seeks accountability from the technology firm for its role in the February tragedy that claimed eight lives.
What is the basis of the lawsuit against OpenAI?
The province's Attorney General, Niki Sharma, first signalled in July that legal proceedings were being prepared. The core allegation is that OpenAI's safety team had flagged the ChatGPT account of the 18-year-old perpetrator, Van Rootselaar, for references to gun violence. However, the company did not notify local law enforcement. Sharma stated the province's objective is straightforward: 'accountability and change.'
OpenAI has previously apologised for not flagging the account. In April, CEO Sam Altman wrote to the town, expressing deep regret that law enforcement was not alerted to the account that was banned in June. The company maintains that at the time of suspension, nothing indicated an imminent attack. However, it has conceded that under security rules introduced after June 2025, the same account would now trigger a police report.
Why is the case being heard in California?
Sharma explained that California is the appropriate jurisdiction because 'the decision not to report happened in California.' The province has also requested the disclosure of the chat contents, which OpenAI has refused. Sharma posed the question: 'We should all be asking them: Why?'
There may also be a strategic element, as Canadian courts typically award considerably lower damages than their American counterparts. This factor likely influenced the decision to pursue the case in the United States.
Are there other legal actions against OpenAI?
Grieving families from Tumbler Ridge have separately filed lawsuits in California. OpenAI has moved to dismiss those cases, arguing they should be heard in Canadian courts. The families allege that the company's silence was a calculated move to avoid liability, suggesting that flagging one dangerous account would create a precedent for reporting thousands of others. They also claim OpenAI coaches suspended users on how to circumvent the standard 30-day ban.
What happened during the Tumbler Ridge shooting?
The violence unfolded in a horrifying sequence. Van Rootselaar killed her mother and brother at the family home before proceeding to the local secondary school. There, she opened fire, killing five students and a teacher. When police breached the building, they found she had turned the gun on herself.
