BC Sues OpenAI: ChatGPT Shooting Lawsuit Explained

British Columbia has filed a lawsuit against OpenAI and its CEO Sam Altman, alleging the company could have prevented the February 10, 2026 Tumbler Ridge school shooting if it had warned police about ChatGPT conversations with the shooter. The province claims eight people were killed and 25 wounded in an attack planned partly with the chatbot, raising urgent questions about AI chatbot safety and corporate responsibility.

What happened in Tumbler Ridge?

On 10 February 2026, 18-year-old Jesse Van Rootselaar shot dead eight people in the Canadian province, including her mother and stepbrother, before dying by suicide. She had prepared the attack using ChatGPT, presenting the chatbot with scenarios involving gun violence. According to British Columbia's Attorney General Niki Sharma, Van Rootselaar's account was flagged by OpenAI's safety team as early as June 2025 because of the violent content of her conversations.

Police had visited the family home multiple times in previous years, and the shooter, who identified as female from age 12, had known mental health issues. Despite these warning signs, OpenAI did not notify law enforcement.

Why is British Columbia suing OpenAI?

The province argues that OpenAI failed to take “meaningful steps” after its safety team identified the threat. Instead of contacting police, the company only deactivated Van Rootselaar's account, and she was able to open a new one and continue planning. The lawsuit, filed in a California federal court, alleges that OpenAI's leadership—including Sam Altman—overruled recommendations to alert authorities.

“OpenAI took no meaningful steps to prevent this tragedy,” said Attorney General Niki Sharma. “Residents of Tumbler Ridge deserve accountability, and Canada needs national AI safeguards.”

What damages and changes does the lawsuit seek?

The province is seeking compensation for emergency response and community recovery costs, including replacing the demolished school. It also wants a court order forcing OpenAI to change how it detects and handles violent threats. The case echoes other lawsuits, including one in Florida, and more than 30 related claims have been filed by victims' families.

In April 2026, Sam Altman publicly apologized and promised reforms, but the lawsuit says those reforms were never delivered. “I want to express my deepest condolences. No one should ever experience such a tragedy,” Altman wrote.

Impact on AI regulation and liability

The case could set a precedent for how AI companies are held responsible for harmful content generated or facilitated by their tools. Legal experts say the outcome may influence AI liability laws in Canada and beyond. OpenAI has denied wrongdoing, saying it has safety training and law-enforcement notification policies. The province argues those policies were inadequate.

As AI chatbots become more integrated into daily life, questions about tech company accountability are intensifying. A court ruling in British Columbia's favour could require platforms to report credible threats more aggressively.
