Quebec publisher Les Éditions du Boréal terminated its relationship with author Thélyson Orélien on October 21, 2026, citing new evidence of artificial intelligence use in the writing process of his prize-winning novel 'C’était ça ou mourir'. The publisher stated new information confirmed AI was used, despite Orélien's repeated assurances to the contrary.

This decision impacts the integrity of literary awards and publishing trust at a time when artificial intelligence's role in creative works is a growing concern for authors and publishers. Publishers are grappling with how to address AI use, while authors face scrutiny and potential career consequences.

What the records show

Les Éditions du Boréal announced on October 21, 2026, it would not reprint Orélien's novel and would not publish any other books by him. The publisher's statement revealed that "New information, confirmed in recent days, indicates that artificial intelligence was used in the writing process" of 'C’était ça ou mourir'. This evidence included "traces of AI tags in the metadata of some documents". Earlier analyses by an anonymous X account and Le Monde using the AI content detector tool Pangram had suggested significant AI involvement, with one report indicating over 95% of the text was AI-produced with a "high confidence level".

The timeline

Allegations first emerged in September on an anonymous X account, "Balance ton Claude," shortly after Orélien received the Prix du Roman Fnac. On September 25, the Académie Goncourt removed 'C’était ça ou mourir' from the longlist for France's top literary prize, citing "convergent result of several analyses" showing the novel was "in all likelihood very largely the product of an artificial intelligence". Orélien announced last week that he would no longer gather evidence to support his denial. This past Wednesday, his publisher, Les Éditions du Boréal, confirmed their decision to drop the author.

What changed and for whom

Les Éditions du Boréal had initially supported Orélien, stating they lacked elements to confirm AI use, but an external deep analysis of "all working versions of the novel" led to the change. The publisher recognized that their decision would have "long-term consequences for the operation of Boréal, for our fellow publishers and for the book industry in general". For Orélien, the dropping by his publisher follows his removal from the Prix Goncourt longlist.

What the subject has said publicly

Orélien has consistently denied using AI for the core creation of his novel. In a statement to Agence France-Presse earlier this month, he called the allegations "slander and heresy". He admitted to using AI tools "here and there" for research, specifically for foreign idioms and "historical research" in the "creative process". He maintained that "not a single sentence in this book was created by a machine, nor the meaning or the structure of a story that comes from my gut". On October 13, in a press release, Orélien wrote that attributing his text to a machine challenged his identity as a writer and his humanity. He did not respond to The Canadian Press' request for comment.

What we could not confirm

The exact extent to which AI was used in the creation of 'C’était ça ou mourir' remains unknown to the publisher, and they believe "we will probably never have a definitive answer in this regard".
