The lawsuit, filed in US federal court on Monday, marks the first legal action by the Canadian province against OpenAI over the Tumbler Ridge shooting. The 18-year-old shooter, Jesse Van Rootselaar, killed five children and an education assistant at Tumbler Ridge Secondary School before taking their own life. Prior to the school attack, Van Rootselaar also shot their mother and half-brother, bringing the total death toll to eight.
Media reports revealed that OpenAI's safety team had flagged Van Rootselaar's ChatGPT activity for references to gun violence months before the shooting, but the company did not alert local authorities. In April, OpenAI CEO Sam Altman issued an open letter apologising to the families, writing: "I am deeply sorry that we did not alert law enforcement."
Families of the victims have already filed separate lawsuits against OpenAI over its failure to warn authorities. British Columbia's complaint goes further, detailing the extensive costs of the disaster response, including the demolition of the school. The province argues that OpenAI and Altman owe the community more than an apology — they must pay for rebuilding, recovery, and healing.
"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. She told reporters that the province had asked OpenAI to disclose the contents of the shooter's chats, but that the company had refused. "We should all be asking them: Why?" she said.
The lawsuit raises questions about the responsibilities of technology companies when they become aware of credible threats of serious violence. OpenAI has not yet responded to requests for comment regarding the new legal action.
