A sports fan, Athanase David was president of the Montreal Canadiens ice hockey club from 1930 to 1935.
In 1928 he partnered with Montreal stockbroker Ernest Savard and American baseball executive George Stallings to revive the Montreal Royals baseball franchise as part of the International League and to build Delorimier Stadium.
