The Canadian publishing house Éditions du Boréal officially ended its professional relationship with Haitian-Canadian author Thélyson Orélien on October 21, 2026, after confirming the use of artificial intelligence in his debut novel, 'C'était ça ou mourir'. This decision followed an external analysis that revealed "traces of AI tags in the metadata of certain documents" related to the novel.

This incident adds to ongoing discussions within the literary world regarding authenticity, trust, and the ethical boundaries of AI tools in creative writing.

What the records show

Éditions du Boréal stated it had gathered all working versions of the novel and hired an external party to analyze various drafts. The results, obtained the week of October 21, 2026, showed "traces of AI tags in the metadata of certain documents". Despite this finding, the publisher indicated that it does not know the full extent to which AI was used and may never have a definitive answer. The publisher’s statement on Wednesday confirmed that new evidence indicated AI use, contrary to Orélien's previous assurances. Boréal emphasized that the fundamental issue was the relationship of trust between authors and publishers.

The timeline

Allegations of AI use in Orélien's novel, 'C'était ça ou mourir', first surfaced on social media in September 2026, initiated by an anonymous X account. This account claimed an AI detector flagged the book as "almost entirely" written by AI. Following these accusations, the novel was removed from prestigious award shortlists, including the Prix Goncourt, in September 2026. Promotional activities for the book were also suspended by Éditions du Boréal in September, initially citing concerns for the author's well-being. The publisher had previously tried to work with Orélien to gather evidence to refute the allegations. However, after Orélien reportedly stopped providing further material, Boréal commissioned an in-depth external analysis. The publisher announced the termination of its relationship on October 21, 2026.

What changed and for whom

As a direct consequence of the verified AI use, Éditions du Boréal announced it would not reprint 'C'était ça ou mourir' and would not publish any future works by Thélyson Orélien. The novel had previously won multiple literary awards and was slated for translation into several languages.

What the author said

Thélyson Orélien had repeatedly denied using artificial intelligence to write his debut novel. However, he did acknowledge instances of past plagiarism in earlier works, for which he issued an apology, describing them as "unacceptable mistakes in his youth". Orélien did not provide a comment to The Canadian Press regarding the termination of his publishing contract.

What we could not confirm

We could not confirm the exact extent to which AI was used in the creation of Thélyson Orélien's novel, 'C'était ça ou mourir'.
