The claim was filed in B.C. Supreme Court on Monday on behalf of Gebala by her mother, Cia Edmonds.

It alleges that the company designed its chat tool, ChatGPT, in such a way that there were risks users "would become psychologically and socially dependent" upon it.

The lawsuit states that the company "had specific knowledge of the shooter's long-range planning of a mass casualty event," but "took no steps to act upon this knowledge."

CBC News has reached out to OpenAI for a response to the lawsuit. None of the claims have been proven in court.
