Communism. On
May 1, 1929, during her time in Berlin, Roback joined the
Communist Party of Germany. She felt seduced by the
socialists, but she believed they did not put their words into action, hence she shifted her support to
Marxism-Leninism. In her 1988 interview with Nicole Lacelle, Roback said that it was during that period that she gained genuine political consciousness. In the fall of 1932, with the
Nazi Party steadily gaining power, Roback, a Jew, foreigner, and communist, was left to return to Montreal on the advice of her professors, whereupon she joined the
Communist Party of Canada. In 1934, she spent a few months in the
Soviet Union with a lover. Returning for good to Montreal, she participated in the organization of the unemployed, which was led by
Norman Bethune. She also worked at the Young Women's Hebrew Association. In 1935, she established the first Marxist bookshop in Montreal, Modern Book Shop, on
Bleury Street. Roback helped unionize

Fred Rose's ultimately successful campaign in the
1943 Cartier by-election for the Communisy Party. After steadily distancing herself from the CPC, Roback left the party in 1958 after the
Soviet invasion of Hungary. In 1960, she became a member and played an active role in the organization "Voice of Women" (
La Voix des Femmes in Montreal) alongside

Saint-Henri to receive decent housing. At the age of 83 and in the pouring rain, she participated in the women's march for pay equity. In 1985, she became an honorary member of the Canadian Institute for Research on Women. She died in
