Born in Mont-Laurier on 28 May 1963, Claer wrote his first poems after reading Mary Ingalls in Échos Vedettes [fr]. At the age of 20, he submitted his first poems to Alain Stanké, who rejected them. Assigned female at birth, he transitioned in the 1990s.[3] He earned a Bachelor of Arts in communications from the University of Ottawa.[4]
While living in Gatineau, Claer had his first novel, Nue, un dimanche de pluie, published in 2001.[5] In the 2010s, he returned to poetry, publishing works such as Squatteur d'imaginaire and Mordre jusqu'au sang dans le rouge à lèvres.[6] In 2018, he participated in SlamOutaouais.[7] In 2021, he was a finalist for the Prix du Conseil des arts et des lettres du Québec.[8] In 2023, his work La Papesse woke was selected by the jury of Projet 3e œil.[9]
In addition to his writing, Claer took part in an Opération Gareautrain campaign for suicide prevention and discussed the suicidal thoughts that haunted him prior to his transition.[10] He also expressed his sexuality in many of his works.[8]
Claer died on 4 January 2025, at the age of 61.[11]
