Calgary Flames assistant general manager Chris Snow died Saturday of a “catastrophic brain injury” after suffering cardiac arrest earlier this week, his wife said.

He was 42.

“Today we hugged Chris for the last time and said goodbye as he went to give four people the gift of life by donating his kidneys, liver and lungs,” Kelsie Snow posted on X.

“We are deeply broken and deeply proud. In life and in death, Chris never stopped giving. We walk forward with his light guiding us.”

Snow, who had battled ALS since 2019, was on life support following the cardiac arrest.

In a statement, the Flames said, “We, along with the entire hockey community, are mourning the passing of Chris Snow. Even while battling ALS, Chris dedicated his life to helping others and he changed the lives of so many.”

Kelsie Snow said on social media her husband went into cardiac arrest Tuesday caused by a catastrophic brain injury from a lack of oxygen, which doctors did not expect him to wake up from.

Flames GM Craig Conroy told the Associated Press that Snow never complained or showed he had a bad day, continuing to perform his job at a high standard.

“Through his journey, Chris became a true inspiration for all who knew him and an incredible advocate for everyone affected by ALS,” Conroy said. “We will never replace a person like Chris. We simply pay tribute to him by moving forward with the same passion that he brought to his life each day.”

NHL Commissioner Gary Bettman called Snow a “remarkable man whose courageous and relentless battle with ALS has been an inspiration to so many.”

“An innovative student of our game with an expertise in data analysis, Chris supervised the creation and build out of the Flames’ analytics department and was influential in all facets of the Club’s Hockey Operations decision-making,” Bettman said. “First and foremost, however, he was a beloved husband to Kelsie, a devoted dad to Cohen and Willa, and a friend to everyone in hockey fortunate enough to have met him. The Snows’ willingness to share the trials and triumphs of Chris’s lengthy ALS journey has inspired so many and profoundly increased awareness of the need to find a cure for this debilitating disease.”

Before Friday’s Flames’ preseason game, he was honored with a video tribute.

Snow joined the organization in 2011 and worked his way up the ladder to assistant GM.

Toronto Maple Leafs GM Brad Treliving, who worked with Snow in Calgary, said he was devastated by the news about his friend and colleague.

“ ‘Snowy’ was a true example of strength, courage, grit and compassion,” Treliving said. “He was a cherished friend who deeply impacted our lives. … Chris inspired us all as he faced his relentless battle with ALS head on, refusing to let it define him or derail his spirit.”

Before joining the Flames, Snow was director of hockey operations for the Minnesota Wild from 2006-10.
