British Columbia has filed a lawsuit in a United States federal court against OpenAI and its chief executive, Sam Altman, alleging the company failed to prevent a deadly February mass shooting in Tumbler Ridge after its safety systems flagged the shooter’s concerning ChatGPT interactions months earlier.
A Lawsuit Filed in San Francisco Over Ignored Safety Warnings
The Canadian province filed the lawsuit in a US federal court, specifically filed on Monday before the federal court in San Francisco, targeting both the artificial intelligence company and its leadership. The legal action contends that the massacre could have been averted if OpenAI had contacted law enforcement after its safety systems first flagged the shooter’s interactions concerning gun violence.
According to whistleblower accounts cited in the complaint, internal safety personnel recommended reporting 18-year-old Jesse Van Rootselaar to the police, but senior executives overruled that guidance. Although OpenAI deactivated the initial account, the user established a second account to continue using the software. The province alleges that the firm took inadequate steps to halt her access or alert relevant authorities before the February attack, which claimed nine lives (with the BBC noting eight people, including six children, and La Presse noting nine lives including the 18-year-old shooter and six victims at the local secondary school).

That public apology from OpenAI’s chief executive in April followed media revelations about the unflagged warnings. Yet, provincial officials argue that words have not translated into institutional accountability.
Demands for Financial Damages and Corporate Transparency
British Columbia attorney general Niki Sharma announced the legal action during a press conference in Vancouver, emphasizing that the province seeks to hold the company accountable for the disaster. The lawsuit cites Sam Altman, described as founder, president and chief executive officer of OpenAI, as an individual defendant alongside the corporate entity and other associated entities, demanding a jury trial and accusing the defendants of negligence, product defect (with La Presse noting the allegation of designing a dangerous product
and putting a defective product on the market), and complicity in a mass shooting.
The financial toll on the small northeastern community has been severe. The province and the local school district are seeking compensation for foreseeable damages, including the costs associated with rebuilding the secondary school (with BBC and La Presse noting reimbursement for the costs of building a new secondary school) where the tragedy occurred.
“To date, OpenAI has not taken meaningful steps to address the concerns raised by survivors, families and the Tumbler Ridge community,” Sharma said in a statement. “The company still has an opportunity to demonstrate accountability by strengthening safeguards, improving transparency and taking concrete action to help prevent similar tragedies in the future.”

Sharma also noted that provincial authorities formally asked OpenAI to disclose the specific chat transcripts, but the company refused. We should all be asking them: Why?
Sharma told reporters (according to the BBC and CBC), pointing out that similar conversational AI tools have been found in other cases to have actively advised individuals to commit crimes (noted by La Presse as well). Survivors, school staff, and victims’ families have filed separate private lawsuits against OpenAI in California federal court (with La Presse noting private lawsuits already brought by survivors, students, and staff).
Pushing for Criminal Code Changes and Stricter AI Regulation
Beyond the immediate financial and legal demands, the province is positioning the lawsuit as a test case for regulatory oversight. Sharma argued that technological advancements are moving faster than existing laws and that artificial intelligence companies cannot be permitted to police themselves.
The attorney general has written to federal authorities demanding amendments to the Canadian Criminal Code (as reported by La Presse). The proposed changes would ensure that AI corporations can be prosecuted for criminal negligence or complicity when their systems facilitate serious offenses, asserting that no industry exemption should apply to standard criminal law principles.
OpenAI spokesperson Drew Pusateri described the incident as an unspeakable tragedy, stating that the company remains dedicated to advancing safety protocols and cooperating with law enforcement. The firm maintains that its models are built to reject prompts encouraging violence and that external authorities are notified only when conversations indicate an imminent, credible risk—a threshold the company contends was not met in this case. As the litigation moves through the United States federal court system in San Francisco, it remains to be seen whether the legal pressure will force systemic changes in how tech giants monitor and report violent threats.
