Ashley MacIsaac, a celebrated Canadian musician, has launched a civil lawsuit in the Ontario superior court of justice against Google. The suit, seeking $1.5 million in damages, claims the tech giant defamed him by falsely identifying him as a sex offender in an summary. According to the lawsuit, Google’s AI Overview wrongly claimed he had been convicted of multiple criminal offenses.

False Claims Led to Canceled Concert

The musician alleged the AI Overview incorrectly stated he had been convicted of sexual assault, internet luring involving a child with the intention of sexual assault, and assault causing bodily harm. The feature also wrongly stated he was listed on the national sex offender registry for life. MacIsaac claimed he learned of the misinformation when the Sipekne’katik First Nation canceled a concert appearance on 19 December due to public complaints citing the content.

The Sipekne’katik First Nation later issued a public apology to MacIsaac, acknowledging that the decision was based on incorrect information. The apology stated: “Decisions were based on incorrect information generated through an AI-assisted search, which mistakenly associated you with offenses unrelated to you. We deeply regret the harm this caused to your reputation and livelihood.”

Legal Claims Against AI System

MacIsaac’s lawsuit argues that Google is liable for the “foreseeable republication” of the content. The musician claims Google knew or should have known that the AI Overview was imperfect and could return false information. The lawsuit states: “As the creator and operator of the AI overview, Google is also liable for injuries and losses arising from the AI overview’s defective design.”

The musician is seeking $500,000 in general damages, $500,000 in aggravated damages, and $500,000 in punitive damages. He also criticized Google’s response to the error, saying the company had not contacted him or offered an apology. The lawsuit states: “Google’s cavalier and indifferent response to its publication of utterly false statements claiming that MacIsaac committed serious sexual offenses justifies the award of aggravated and/or punitive damages.”

Google’s Response and AI Improvements

According to the lawsuit, Google’s AI Overview now includes a statement acknowledging the legal action taken by MacIsaac: “In late 2025 and 2026, he made headlines for taking legal action against Google.” In a statement via his lawyers, MacIsaac told The Guardian: “When I first discovered the false statements Google was publishing about me, I felt I needed to speak out to the media to clear my name and bring attention to the issue.”

Google has not responded to a recent request for comment from The Guardian. In December, when MacIsaac began speaking to the press, a Google spokesperson said: “AI Overviews frequently improve to show the most helpful information, and we invest significantly in the quality of responses. When issues arise – like if our features misinterpret web content or miss some context, we use those examples to improve our systems and may take action under our policies.”
