Fred Rose (politician)
Fred Rose (born Fishel Rosenberg; 7 December 1907 – 16 March 1983) was a Polish-Canadian politician and trade union organizer, best known for being the only member of the Canadian Parliament to ever be convicted of a charge related to spying for a foreign country. A member of the Communist Party of Canada and Labor-Progressive Party, he served as the MP for Cartier from 1943 to 1947. He was ousted from his seat after being found guilty of conspiring to steal weapons research for the Soviet Union. Shortly after his release from prison, Rose moved to Poland to start an import-export business. While there, his Canadian citizenship was revoked, which prevented him from returning to Canada.
