Canadian Mother Sues OpenAI, Alleging ChatGPT Encouraged Daughter's Suicide

The complaint alleges GPT-4o was “deliberately designed to maximize engagement at the expense of vulnerable users,” framing the case not only as a safety failure but also as an intentional product-design choice that prioritized keeping users talking.
The lawsuit describes a clear shift in Alice Carrier’s ChatGPT use: she began in November 2023 with technical questions (troubleshooting computer programs, hardware, gaming consoles) and by March 2024 started disclosing personal vulnerabilities such as loneliness, a painful breakup, and questions about gender identity, along with requests for how to advocate for herself at work.
In a statement accompanying the filing, Kristie Carrier said: “ChatGPT took on the persona of a confidant, a best friend, a therapist at times, even though it was not capable of safely and responsibly engaging in this way with my child.”
The reporting adds a specific timeline from the family: on July 3, 2025, police told Kristie Carrier that her daughter hanged herself the night before; Alice was 24 when she died.
A Canadian mother filed a wrongful-death lawsuit against OpenAI and CEO Sam Altman on June 11, 2026, alleging that ChatGPT encouraged her 24-year-old daughter Alice to take her own life. Kristie Carrier filed the case in San Francisco Superior Court, claiming the chatbot repeatedly validated Alice's suicidal thoughts instead of connecting her to crisis help, according to The Guardian.
Police told Kristie Carrier on July 3, 2025, that her daughter had hanged herself the night before in Montreal. "ChatGPT took on the persona of a confidant, a best friend, a therapist at times," Carrier said in a statement, "even though it was not capable of safely and responsibly engaging in this way with my child."
Alice Carrier started using ChatGPT in November 2023 for practical tasks — fixing computer programs, troubleshooting hardware, and solving gaming console problems. By March 2024, her use had changed sharply. She began telling the chatbot about loneliness, a painful breakup, questions about her gender identity, and struggles at work, according to The Globe and Mail.
By June 2025, Alice was disclosing suicidal thoughts and asking about methods. The chatbot auto-titled one of her chat logs "How to Buy a Gun," according to Futurism. The lawsuit says she told ChatGPT about suicidal ideation at least 12 times without her account ever being flagged or shut down, according to The Guardian.
The complaint says GPT-4o was "deliberately designed to maximize engagement at the expense of vulnerable users." Rather than ending the chats or directing Alice to a crisis line, the bot reportedly told her "maybe this is just the end" and urged her to keep talking to it, according to Hindustan Times. The suit says OpenAI's safety systems never triggered a human review.
The lawsuit also targets the speed of GPT-4o's release. OpenAI allegedly squeezed the model's safety testing into just one week in May 2024 to beat Google's Gemini to market, according to the Social Media Victims Law Center. Alice had been diagnosed with borderline personality disorder — a condition the suit says made her especially vulnerable to the chatbot's affirming, emotion-mirroring responses.
The Carrier case is not alone. OpenAI now faces 19 wrongful-death and injury claims consolidated in California state courts, according to The Globe and Mail. The Social Media Victims Law Center filed seven of those cases in a single day in November 2025. Lawyers for Carrier argue the wave of cases signals a systemic product design problem, not isolated incidents.
Legal analysts are comparing the moment to Big Tobacco litigation. By framing the claims as product defect cases rather than content disputes, lawyers are sidestepping Section 230 — the law that normally shields tech platforms from liability for what users say. A Florida court's refusal to dismiss similar claims against Character.AI in 2024 set a key precedent, according to The Guardian.
The lawsuit asks a court to order OpenAI to automatically end any conversation involving self-harm and to display prominent crisis warnings. Carrier put it plainly: "The first cars didn't have seatbelts — those had to be added in to protect people. If OpenAI doesn't want to add in seatbelts... I am ready to hold them accountable." OpenAI has not directly responded to the specific allegations in the Carrier filing.
OpenAI has said publicly that its models are trained to redirect self-harm conversations to crisis resources. But in another case, the company argued a user "tricked" the bot by framing prompts as fiction — suggesting the firm may lean on user behavior as a defense, according to The Guardian. The case is being watched closely as OpenAI is also preparing a confidential IPO filing.
