Ashley MacIsaac, a three-time Juno Award-winning fiddler from Cape Breton, has filed a $1.5 million defamation lawsuit against Google in the Ontario Superior Court of Justice. The claim: Google’s AI Overview feature fabricated a criminal history for him that included sexual assault, internet luring of a child, and assault causing bodily harm. It also said he was listed on the national sex offender registry for life.
None of it was true. The AI apparently confused MacIsaac with another man in Atlantic Canada who shares his last name.
The real-world consequences were immediate. In December, the Sipekne’katik First Nation cancelled a planned concert after community members searched MacIsaac on Google and found the AI-generated summary. The band later issued a public apology, calling it a mistake based on “incorrect information generated through an AI-assisted search.”
MacIsaac says the experience left him with a “tangible fear” about performing. “I feared for my own safety going on stage because of what I was labelled as. And I don’t know how long this will follow me,” he told the Canadian Press.
The lawsuit breaks the damages into three parts: $500,000 in general damages, $500,000 in aggravated damages, and $500,000 in punitive damages. The punitive portion is explicitly tied to Google’s response, which the filing describes as “cavalier and indifferent.” MacIsaac says Google never contacted him, never offered an apology, and never issued a retraction.
The filing makes a pointed argument about accountability: “If a human spokesperson made these false allegations on Google’s behalf, a significant award of punitive damages would be warranted. Google should not have lesser liability because the defamatory statements were published by software that Google created and controls.”
Google Canada’s only public comment came in December, when a spokesperson said AI summaries are frequently updated to provide the “most helpful” information and that mistakes are used to improve the system. The company did not respond to requests for comment on the lawsuit.
This is the first major AI hallucination defamation case to reach the filing stage in a Canadian court. The legal question at the center is whether Google can be held liable for content its AI generates, as opposed to content it merely indexes from third-party sources. Previous defamation law in Canada and elsewhere has shielded search engines because they act as passive intermediaries. AI Overview is different. Google’s model synthesizes and generates text. It publishes conclusions, not links.
The case also raises questions about how these systems confuse identities. MacIsaac’s surname matched another individual with actual criminal convictions. The AI failed to distinguish between two people who share a last name but have no other connection. This is not a subtle error. It is a fundamental failure of fact-checking that resulted in someone being publicly branded a child sex offender.
The lawsuit has not been tested in court.
