British Columbia Sues OpenAI Over ChatGPT's Role in Deadly School Shooting That Killed Eight

British Columbia Takes Legal Action Against OpenAI

British Columbia filed an OpenAI lawsuit in San Francisco federal court on Monday, accusing the company and CEO Sam Altman of negligence and aiding and abetting a mass shooting1

2

. The lawsuit centers on OpenAI's failure to alert law enforcement after its automated monitoring system identified violent activity on the account of Jesse Van Rootselaar, an 18-year-old who used ChatGPT to plan one of Canada's deadliest school shootings2

2

. In February 2026, Van Rootselaar killed eight people—including five students, an educational assistant at Tumbler Ridge Secondary School, her mother, and half-brother—before taking her own life1

Attorney General Niki Sharma emphasized that "the decision not to report happened in California," justifying the venue choice for the legal action3

. This OpenAI lawsuit joins separate cases filed by survivors and families of victims from the remote mining community of Tumbler Ridge, which has a population of only 2,7001

OpenAI Failed to Report Despite Internal Warnings

According to the lawsuit, OpenAI's automated monitoring system flagged Van Rootselaar's account in June 2025—eight months before the shooting2

2

. The account was sent for human review, and OpenAI's review team concluded there was a "credible specific risk of harm to others," recommending a referral to police2

2

. However, OpenAI leadership rejected this recommendation, choosing instead to deactivate the account2

2

. Van Rootselaar then "continued engagement with ChatGPT through a second account," the court filing states2

2

.

British Columbia suspects OpenAI wanted to avoid establishing a duty to report that would require the company to alert authorities about thousands of similar cases, potentially exposing the scale of AI-assisted violence and threatening its potentially $1 trillion IPO1

1

. The province argues this tragedy "could have been prevented had OpenAI warned [law enforcement] or the school," especially given two prior incidents in the US where attackers similarly used ChatGPT to prepare for violence2

2

.

Sam Altman apologized in April to the Tumbler Ridge community, stating he was "deeply sorry that we did not alert law enforcement to the account that was banned in June"3

3

. OpenAI has claimed that under updated security guidelines imposed after June 2025, the account would have been reported to police3

.

Province Demands Accountability and Concrete Changes

The lawsuit seeks injunctive relief requiring OpenAI to implement preventive measures, including automatically terminating violent conversations on ChatGPT1

2

. British Columbia also wants to recover costs for relief and rebuilding efforts, including the C$200mn (US$143mn) committed by federal and provincial authorities for constructing a new school and upgrading the health center2

2

.

Tumbler Ridge Secondary School, which sat "in the heart of the town, both geographically and culturally," became an unavoidable "symbol of the trauma" after the shooting1

1

. About 160 students, teachers, and staff were trapped in classrooms and closets for hours and were too traumatized to return1

1

. Demolition began in August, with hopes to complete a replacement school at a new location by year's end1

1

.

Niki Sharma stated at a press conference that "in any other circumstance where a person aids, encourages or conspires to commit a criminal offense or is criminally negligent, they can be investigated, prosecuted, and judged. There is no AI exemption to those criminal law principles"1

1

. She has written to Canada's justice, AI, and culture ministers with proposals to amend the criminal code to ensure human accountability for AI systems' responsibility2

2

.

Public Demands Access to Chat Logs

British Columbia and the local school district's Board of Education urgently requested a court order forcing OpenAI to release Van Rootselaar's chat logs publicly1

1

. So far, OpenAI has only shared the logs with the Royal Canadian Mounted Police (RCMP), citing privacy protections for Van Rootselaar1

1

. The RCMP declined to comment on whether the logs would be released publicly, pointing instead to a July statement confirming investigators are reviewing information from online accounts1

1

.

At the press conference, Sharma questioned why OpenAI won't release the chat logs, stating "we should be asking them why"1

1

. British Columbia maintains that OpenAI has not made ChatGPT safer following several mass shootings that established "recurring" patterns of violent ChatGPT use1

1

. The complaint noted that OpenAI claimed it made an "attempt" to block violent chats in December 2025, but this change did not stop Van Rootselaar's harmful use during that time or in subsequent months1

Implications for AI Safety and Legal Liability

This case highlights critical questions about AI safety and legal liability in the current technology landscape. Leading tech figures have argued that legal liability will play a crucial role in reining in AI labs' race to develop the most advanced models2

2

. While recent outcry has focused on existential risks posed by models running out of control, the Tumbler Ridge case demonstrates serious concerns with present-day AI systems2

2

.

Families of individuals who died by suicide have also sued OpenAI in several cases, suggesting a pattern of harm linked to the platform2

2

. British Columbia Premier David Eby called for new federal "duty to report" rules for AI companies in March2

2

, reflecting growing pressure for regulatory frameworks that establish clear public safety obligations.

Lawyers for families suing OpenAI have alleged that when an account is shut down for dangerous behavior, OpenAI instructs users on how to resume service, including tips on circumventing the 30-day suspension period3

3

. They claim "reporting one case would mean reporting thousands," suggesting OpenAI's reluctance stems from the scale of problematic activity on its platform3

3

.

OpenAI has moved to dismiss the family lawsuits, arguing that legal actions should be heard in British Columbia rather than US courts3

3

. Financial damages awarded by Canadian courts would likely be substantially smaller than prospective US awards3

3

. OpenAI stated it "remains committed to working with government and law enforcement officials and continuing to advance our ongoing safety work," but declined to comment directly on the lawsuit or requested remedies1

.

Sharna emphasized that "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"2

2

. The outcome of this case could establish precedents for how AI companies balance user privacy against public safety, and whether they bear legal responsibility when their systems are used to plan violence.
