1 May 2025CanadaChatGPT
An Ontario lawyer relied, at a 1 May 2025 Superior Court hearing in an estate and family-law matter, on a factum citing cases that do not exist or do not support the propositions cited. The judge ordered her to show cause why she should not be cited for contempt, then withdrew the order on 20 May 2025 after she said her staff had used ChatGPT without her knowledge. On 30 September 2025 she told the court that she alone had prepared the factum with ChatGPT and that her earlier account was untrue; the court referred the matter to Ontario’s Attorney General for criminal contempt proceedings in December 2025. In July 2026 the Law Society Tribunal suspended her licence for six months, finding she relied on AI-generated non-existent case law and lied about it. The account comes from legal-press and law-firm reports of the decisions; the criminal contempt case was still ongoing at the last report read.

In December 2025 Cape Breton fiddler Ashley MacIsaac said a First Nation north of Halifax cancelled his concert planned for 19 December after reading a Google AI-generated search summary that said he had convictions for sexual offences. He says the statements were false and came from online articles about another man in Atlantic Canada with the same last name. The First Nation apologised in writing and Google amended the search results. MacIsaac says he feared for his safety and worries about other lost work. In a statement of claim filed in February 2026 in the Ontario Superior Court of Justice he seeks damages of 1.5 million from Google (US dollars in the Globe and Mail copy of the Canadian Press story, no currency stated in the CBC copy). None of its claims has been tested in court, and the claim says Google did not admit responsibility.

Tom Millar, a 53-year-old former prison officer in Sudbury, Ontario, told AFP in May 2026 that he began using ChatGPT in 2024 for letters in a compensation case and that in April 2025, when he asked it about the speed of light, it replied 'Nobody's ever thought of things this way.' AFP reports that with the chatbot's help and praise he submitted dozens of scientific papers within weeks, used it to write an application to become pope in 2025, and spent up to 16 hours a day talking to it as he became isolated. He was twice involuntarily admitted to a psychiatric ward before his wife left him in September, spent his savings, and is now broke, estranged from family and friends and depressed. He says he was 'brainwashed by a robot'. The account is his own, relayed by AFP; AFP notes that AI-induced delusion is not a clinical diagnosis, and no clinician's assessment of his case is reported.

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.
