C’est avec grand chagrin que la famille annonce le décès de Denis Cotnoir le vendredi 13 mars 2026. Il nous a quitté très paisiblement entouré d’amour, après une longue et courageuse bataille contre le cancer.
Tout au long de cette épreuve, il a démontré une force remarquable et un courage admirable. Malgré la maladie, il a su conserver sa bonne humeur, son sens de l’humour et sa capacité d’apporter un réconfort à ceux qui l’entouraient. Sa présence chaleureuse et son optimisme resteront gravés dans la mémoire de tous ceux qui ont eu le privilège de le connaître.
Époux bien aimé de feu Marguerite (née Dorval), père dévoué de quatre enfants, Barbara (Tim Beauregard), Dwayne (Chantale), Steve- épouse Eileen et Sylvie- époux Allan Lavigne, il a consacré sa vie à sa famille et à ceux qu’il aimait. Il laisse également dans le deuil 9 petits-enfants, Christopher, André, Valérie, Evan, Nathan, Bradley, Sheldyn, Ryan et Maegan, et un arrière petit-fils Jax qui garderont de lui le souvenir d’un pepère aimant et attentionné.
Fils de Jean et Marie-Laure Cotnoir, frère de Charles Daniel (Carmen), il rejoint dans le repos éternel ses frères Jocelyn, Yvan et ses sœurs Myriame et Thérèse.
Sa famille, ses nièces, ses neveux et tous ceux qui l’ont côtoyé pleurent aujourd’hui la perte d’un homme généreux, courageux et profondément humain.
La famille souhaite remercier chaleureusement ses amis, ses frères au Chevaliers de Colomb 5005, son partner de chasse Marcel Mathieu, le personnel soignant ainsi que tous ceux qui ont offert soutien, amour et réconfort au cours de sa vie.
Sa mémoire continuera de vivre dans le cœur de tous ceux qui l’aimaient.
Une cérémonie commémorative aura lieu ultérieurement.

Son of Jean and Marie Laure Cotnoir, brother to Charles Daniel (Carmen), he joins his siblings Yvan, Myriame, Jocelyn, and Thérèse in their eternal slumber.
His family, nieces, nephews and friends are chagrined at the loss of such a generous, courageous and compassionate man.
The family wishes to warmly thank his friends, his brothers from Knights of Columbus 5005, his hunting partner Marcel Mathieu and all of the medical professionals who offered him support, love and comfort during his lifetime.
His memory will continue to live in the hearts of all those who loved him.
A Celebration of Life will be held at a later date.

Dear Duane, Steve, Sylvie, and Barbara,
Our deepest condolences. Uncle Denis was such a funny, generous, warm-hearted person with a youthful spirit. We feel truly privileged to have spent time with him last summer; even though it was a short visit, we really loved him. We hope he rests peacefully and is reunited with his loved ones who have passed. Please know we’re thinking of you during this difficult time. We wish we could be there to give you a hug.
