Fred Rose (born Fishel Rosenberg;[1] 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.

[2] One of the six children in the family, he attended the "Gymnase Humaniste de Lublin," a Jewish high school in which he learned to speak French.

[vague] In his view, the Communist Party of Canada was to "lead the Canadian workers to establish a system similar to that of the Soviet Union.

He was a close associate of Norman Bethune, a doctor who had aided antifascist and communist fighters first in Spain during the Spanish Civil War and later in China.

In the early stages of World War II, the Communist Party of Canada was formally banned, and many of its leaders interned[clarification needed] by the Padlock Law.

[2] He won with 30% of the vote in a tight four-way race, beating David Lewis of the social democratic Co-operative Commonwealth Federation (CCF) and two others.

Most of the riding's immigrant Jewish population voted for Rose, who benefitted from the perception that the Soviet Union was the main hope for saving Europe's Jews from Hitler.

Rather than return home, Gouzenko defected with documents in September 1945 and claimed to have evidence of a massive Soviet spy ring operating in Canada and the United States.

Rose was alleged to lead the ring of up to 20 Soviet spies, which were targeting primarily atomic weapon research from the Manhattan Project.

Rose was ultimately found guilty of conspiring to turn over information about the explosive RDX to the Soviets,[7] and was sentenced to six years in prison, a term just one day longer than was required to deprive him of his elected seat in the House of Commons.
