The news
On September 21, 2026, British Columbia filed a Tumbler Ridge lawsuit against OpenAI and CEO Sam Altman in U.S. federal court in San Francisco, alleging the ChatGPT maker failed to alert police to threats made on its platform before the February 10 school shooting.
In a statement that day, Attorney General Niki Sharma said the province was suing over OpenAI's failure to notify law enforcement and was working with the board of education for School District 59 Peace River South. Tom's Hardware reported that the province and the district seek emergency response costs and the cost of a replacement school and wellness center, plus punitive and compensatory damages, across eight counts including negligence. They also want safety changes to ChatGPT and the shooter's chat logs.
According to the complaint, as described by Tom's Hardware, OpenAI flagged the shooter's account as early as June 2025 over discussions of gun-violence scenarios. Reviewers judged the user a credible risk and recommended a referral to authorities, but company leaders declined, saying the case did not meet their threshold for a credible and imminent threat. OpenAI banned the account, and the shooter opened a second one, CTV News reported. "One telephone call to the RCMP could have prevented the tragedy," the filing says, referring to the Royal Canadian Mounted Police. None of the allegations have been tested in court.
On February 10, 2026, the 18-year-old shooter killed her mother and half-brother at home, then five students and an education assistant at Tumbler Ridge Secondary School, before dying by suicide, Al Jazeera and Tom's Hardware reported. Al Jazeera reported that Altman published a letter in April saying he was deeply sorry OpenAI had not contacted law enforcement.
An OpenAI spokesperson told CTV News that the company's thoughts remained with the victims and that it was committed to working with government and law enforcement officials and to its ongoing safety work. Sharma said OpenAI had refused to give the province the shooter's chat history.
The province filed in California, where OpenAI is based and where dozens of suits by victims' families and survivors are pending. CTV News reported that the week before, OpenAI moved to dismiss dozens of those claims, arguing they belong in British Columbia. Sharma said the decision not to report was made in the United States.

Why CEOs should care
For general counsel, CISOs and trust-and-safety leaders at any company running a chatbot, this case asks whether a provider that spots a credible threat of violence must tell police. The complaint's core allegation is that front-line reviewers recommended escalation and leadership said no. Companies should write down who decides whether to report a threat, what threshold applies, how fast the call must be made and how the decision is recorded, then check that their privacy policy allows the disclosure. Tom's Hardware noted OpenAI's policy permitted sharing data with authorities to protect the public but did not require it.
For buyers deploying AI assistants to customers or staff, the same questions now belong in vendor due diligence. Ask how the vendor detects threats of violence or self-harm, whether it would notify you, law enforcement or both, and how it stops banned users from simply opening new accounts, as the complaint says happened here. Put incident notification duties in the contract.
For boards and CFOs, the suit shows a government acting as plaintiff to recover public costs and naming the chief executive personally. That raises questions about litigation reserves, insurance coverage for AI-related harms and directors' and officers' exposure when safety decisions are escalated to executives.
The bigger picture
Sharma placed the case alongside British Columbia's earlier suits against tobacco, opioid and vaping companies, and said she had written to federal ministers proposing Criminal Code changes to create a path to human accountability for harms caused by AI. The province's suit adds a public plaintiff to private litigation that has so far been led by families, and raises what Sharma called serious questions about technology companies' responsibilities when they learn of credible threats of violence.
What happened next
On September 24, 2026, Tom's Hardware reported that OpenAI had not yet responded to the province's complaint. The next milestones are OpenAI's formal answer and the court's ruling on OpenAI's motions to dismiss the families' suits in favor of British Columbia courts, which could shape where the province's case is heard. Also watch whether the court orders the shooter's chat logs produced.
