War Measures Act
The party alternated between legality and illegality during the 1920s and 1930s. Because of the War Measures Act in effect at its time of creation, the party operated as the "Workers' Party of Canada" in February 1922 as its public face, and in March began publication of a newspaper, "The Worker". When Parliament allowed the War Measures Act to lapse in 1924, the underground organization was dissolved and the party's name was changed to the Communist Party of Canada.
