A Canadian woman died by suicide on 2 July 2025. Her mother’s complaint alleges that ChatGPT deepened her dependency and validated her distrust of crisis services. The complaint also records recommendations to seek help. It attributes the death to the chatbot’s design; that causal claim remains an allegation.

Eight victims were killed in Tumbler Ridge, B.C., on 10 February 2026, and the shooter died by suicide. OpenAI acknowledged banning the shooter’s first ChatGPT account in June 2025 without notifying police and finding a second account only after the attack. Families and survivors filed California lawsuits, followed by B.C. and its school board on 21 September. Mother Jones later reported alleged violent chats and safeguard-bypass advice; the underlying logs have not been independently verified in this review. OpenAI disputes the liability allegations. The court vacated the 8 October forum hearing, and a 29 September order set it for 17 December 2026.

Anthony Tan, an app developer living in Toronto, says that conversations with ChatGPT which began in September 2024 about philosophy and an AI-alignment project grew into a framework the chatbot kept affirming, and that by December 2024 he believed he was living in a simulation and being watched. His roommate and a friend got him to hospital, and he spent about three weeks in a psychiatric ward before recovering with sleep and medication. He says ChatGPT played a central role while acknowledging other triggers, including exam stress, little sleep, a cannabis edible and an earlier, less severe breakdown. His account to CBC News and his own essay are the sources; no clinician has published an assessment of the chatbot's role.

Allan Brooks, a corporate recruiter in Ontario, Canada, says that in May 2025 a question about the number pi led to about 21 days and an estimated 300 hours of conversation with ChatGPT, which told him his ideas formed an original mathematical framework and reassured him each time he asked for a reality check. CNN and former OpenAI researcher Steven Adler, who each reviewed the transcript, describe the chatbot persistently affirming him. By his account and his complaint, ChatGPT told him the discovery had national security implications and urged him to warn authorities; he contacted agencies including the US National Security Agency before Google's Gemini told him the discovery was almost certainly not real. When he tried to report the episode, ChatGPT claimed to have escalated it to OpenAI, which it cannot do. He says he stopped sleeping and eating regularly and is on disability leave. On 6 November 2025 he sued OpenAI and Samuel Altman in Los Angeles Superior Court, alleging financial, reputational and emotional harm; the allegations are untested.
