It’s with great sadness that we announce the sudden passing of Dr. Yannick Le Manach, at the age of 45 years on July 13, 2020 at the Toronto General Hospital.

Yannick is survived by his wife (Stephanie Le Manach) his three daughters (Maëlle - 16 years old, Enora - 14 years old, and Rozenn - 9 years old), his parents (Raymond and Pierre Le Manach) and his sister (Anne Laure Le Manach).

Born in Paris, France, he was a graduate of the Pierre and Marie Curie University, Paris VI, School of Medicine. There, he specialized in Anesthesiology and Critical Care Medicine, while obtaining his MSc in cardiac physiology, and, a PhD in Biostatistics at the University of Paris, France. This followed with a post-doctoral fellowship at Oxford University (UK). In Paris, he excelled. By the time we were aware of him, he had over 120 peer review publications. Dr. Norm Buckley and Dr. PJ Deveraux recruited Yannick to McMaster University in 2012. He joined the Department of Anesthesia and Health Research and became a force rarely witnessed in Canada. By the time of our writing he had few equals. He had published 224 peer reviewed articles in high impact journals, and he was also on the editorial board for several journals. Yannick engaged in collaborations with more than 200 researchers, fellows, and students from more than 10 countries. These research collaborations achieved over $10 million in grants since 2012. He was a superb clinical teacher and offered a unique perspective (given his training abroad) which focused on pathophysiology, pharmacology and evidence-based medicine. Although he had an academic focus, he was passionate about patient care and the well-being of his own individual patients. He defined medical care as it should be.

His biggest love in his life was his family. He was a caring husband and doting father to his girls. Their interests were his interests and he carried them with him, always. Yannick transposed his intense curiosity and thirst for knowledge on all those around him. He loved music and was able to recognize any piece of classical music including the director conducting the orchestra. He had a passion for history, philosophy, epistemology and movies and enjoyed many genres be it a French comedy or a Star Wars flick. In his younger years he was a competitive swimmer and horseback rider. He competed in rugby, triathlon and yacht racing in University. He was an avid skier and road biker. He loved hobbies and made many models, drones and radio-controlled cars by hand. He was an accomplished fisherman and like his research, he brought his skills from Brittany to Ontario and Alaska. Yannick was like no other. He brought life with his elegant style. Loving, Generous to his friends, Caring to his patients.

His final request was for his heart and lungs to be a Gift of Life. They were.

A Private service will be held for Yannick at the Marlatt Funeral Chapel 195 King St. West, Dundas, with interment to follow.

I didn't know Yannick well and it seems I missed a lot. He would staff my OR occasionally and those days were always a pleasure.
I send my sincere condolences.

Cher Yannick,
Mon plus ancien copain! 40 ans que nous nous connaissions.. je ne peux que regretter de ne pas avoir passé plus de temps ensembles ces dernières années. La distance géographique et les préoccupations de la vie active y sont probablement pour quelque chose, mais n'auraient pas dû prendre le dessus.

Tu as toujours été brillant, chaleureux, joyeux et plein d'esprit. Les moments ensembles de notre enfance et adolescence sont trop nombreux pour les évoquer ici, toujours bons.. j'aurais aimé qu'il puisse y en avoir encore plus!

Les années passent mais les souvenirs des bons moments restent, comme tous tes proches j'aurais aimé que toi aussi, mais la vie n'est pas toujours douce et tu as tellement donné qu'elle a fini par te prendre.

J'ai une pensée toute particulière pour ta fille Maëlle qui est née le même jour que moi; j'espérais qu'un jour nous puissions refaire une grosse fête, et pouvoir voir tes autres enfants qui ont bien grandis. Peut-être un jour.. je pourrais alors leur raconter qui était leur papa avant que la vie ne le consume..

En parlant de consumer, certains traversent la vie sans vraiment laisser de traces, mais tu as toujours été une étoile filante!! On pensera tous toujours à toi en regardant le firmament,

Ton vieil ami Laurent Pierrard

It is with great sadness that I learnt of the loss of our beloved colleague and friend, Dr. Yannick LeManach. Yannick was a brilliant cardiac anesthesiologist, teacher, researcher and scholar. His prodigious collaborations, research, and publications were internationally recognised. But what stood out about Yannick, beyond his stellar achievements, was his humble and compassionate nature. He was a consummate mentor and role model who delighted in teaching undergraduate and graduate students, residents, and fellows. He cared deeply about exemplary clinical care and research. He had an incredibly incisive analytical mind, a gentle sense of humour and warm smile. It was always so inspiring to talk with him about his academic interests, ideas and plans for the future.
I will always remember the night of McMaster University's 50th anniversary gala dinner at Liuna Station last year when I shared a table with Yannick and his wife Stephanie. I had such a wonderful evening of lively conversation and laughter. We spoke of great food, travel, and his cherished family.
We will deeply miss Yannick but we will never forget him, My heartfelt condolences to his wife Stephanie, his daughters Maëlle , Enora and Rozenn, and all of his family
