The Great Depression greatly disturbed Scott and he and other intellectuals formed the League for Social Reconstruction to advocate socialist solutions in a Canadian context. Through the LSR, Scott became an influential figure in the Canadian socialist movement and a founding member of the Co-operative Commonwealth Federation and a contributor to the Regina Manifesto. He went on to serve as national chairman of the CCF from 1942 until 1950.
During the 1950s, Scott was an active opponent of the Duplessis regime in Quebec and went to court to fight the Padlock Law. He also represented one of Jehovah's Witnesses, one Frank Roncarrelli, in Roncarelli v. Duplessis all the way to the Supreme Court of Canada a battle that Maurice Duplessis lost.
On his passing in 1985, Frank Scott was interred in Mount Royal Cemetery in Montreal.
Scott is the subject of a number of critical works, as well as a major biography, The Politics of the Imagination: A Life of F. R. Scott by Sandra Djwa.
