Between the two world wars a range of extreme right-wing groups sprang up across Canada. In this study Martin Robin explores the roots and development of these groups in the 1920s and 1930s.

He begins with the Ku Klux Klan, discussing their origins, rise, and decline, and then considers other right-wing extremist political groups. Some were nativist, most notably Adrien Arcand's National Social Christian Party. Robin provides a detailed account of Arcand's organization, its origins, and ideology. He then turns his attention to Fascist influence and organization in Canada's Italian and German communities during the depression decade. He concludes with a discussion of the decline and suppression of Fascist groups following Canada's entry into the Second World War.
