The Calgary Flames announced on Sunday that co-owner Clay Riddell passed away at the age of 81.
Riddell, who joined the ownership group in 2003, was the founder of Paramount Resources in 1974 and a well-known philanthropist. He was named an Officer of the Order of Canada in 2008, due in part to his philanthropic work with Canadian universities.
"We mourn the passing of a great man of industry, sports, philanthropy and human decency along with our City, Province and Country," Flames vice chairman and CEO Ken King said in a statement the team released. "His legacies to all of us are immeasurable. To his family our gratitude, respect and deepest sympathy."

Incredibly sad. Clay was a titan of our community—in industry, philanthropy, sport, and education. Calgarians feel his legacy now, and we will feel it for many years to come. My heart goes out his family and friends in this difficult time. Know that we all mourn with you today. https://t.co/3Z1d1VMtUz
