During the 1930s and 1940s, the Toronto Police under Chief Constable Dennis "Deny" Draper, a retired brigadier general and former Conservative candidate, returned to its function as an agency to suppress political dissent. Its notorious "Red Squad" brutally dispersed demonstrations by labour unions and by unemployed and homeless people during the Great Depression of the 1930s. Suspicious of "foreigners", the police lobbied the city of Toronto to pass legislation banning public speeches in languages other than English, curtailing union organization among Toronto's vast immigrant populations working in sweat shops.
