Montreal publisher Boréal has cut ties with Haitian-Canadian author Thelyson Orelien, saying artificial intelligence was used to write his best-selling debut novel. In a statement on Wednesday, 21 October 2026, the publisher said new information "confirmed over the past few days" showed AI had been part of the writing of C'était ça ou mourir (It Was Either That or Die), a novel about migration that had already been dropped from the shortlist of France's top literary prize, the Prix Goncourt. Orelien, 38, denies the accusation.
What the publisher found
Boréal opened an inquiry after allegations about the book surfaced in September. It reviewed working versions of the manuscript and hired an outside specialist to analyse the draft files.
| Item | Detail |
|---|---|
| Author | Thelyson Orelien, 38, Haitian-Canadian |
| Novel | C'était ça ou mourir (It Was Either That or Die) |
| Publisher | Boréal (Montreal) |
| Decision | Professional relationship ended, 21 October 2026 |
| Evidence cited | AI-related tags in the metadata of some draft documents |
| Sales | About 65,000 copies in France in the first six weeks |
| Translations | Planned in more than 20 countries; deals now stalled or cancelled |
| Prize | Removed from the Prix Goncourt shortlist |
The review found "traces" of AI tags in the metadata of certain documents. Boréal admitted it cannot establish how much of the text was produced by AI and may never have a definitive answer. It said Orelien had stopped providing information to its inquiry. Only a week earlier, the publisher had publicly supported him.
Background
The novel was one of the surprise literary hits of the year in France. It sold about 65,000 copies in six weeks and was picked for the Goncourt shortlist, the most influential prize in French-language literature. The Goncourt jury removed it after the AI-detection tool Pangram indicated a 100% probability that it contained computer-generated text.
AI-detection tools are controversial. Critics say they can flag human writing by mistake, especially by authors writing in a second language. That is one reason the case has divided readers and writers in France and Quebec.
Orelien's response
Orelien has rejected the accusations from the start, calling them "slander and heresy". He says he used digital tools only for research — in particular to check idioms in foreign languages — and that no sentence in the book was written by a machine. In a newspaper interview on Wednesday he said he had used AI for historical research during the creative process. He says he began writing the book in late 2017, years before tools like ChatGPT were widely available, and when the allegations first emerged he suggested that racism was behind some of the criticism.
Why it matters
The case is one of the first in which a major publisher has dropped a prize-listed author over AI use. It raises hard questions for the book world: how much AI help is acceptable, whether authors must disclose it, and whether detection tools are reliable enough to end a career. Literary prizes and publishers in many countries are now writing rules on AI, and contracts increasingly require writers to declare any use of it.
For readers, the dispute is also about trust. A literary prize is meant to reward a writer's own voice and craft, and a best-seller about migration carries extra weight when readers believe it comes from lived experience. If the publisher's findings hold, it will strengthen calls for clear labelling of AI-assisted books; if Orelien is right, the case will be held up as a warning about relying on detection software to judge a human author.
What happens next
With Boréal out, the future of the novel's translations and further printings is uncertain. Orelien has not said whether he will take legal action or seek a new publisher. The Prix Goncourt will be awarded in early November without his book on the list.
