In June 1940, the government adopted conscription for home service in "The National Resources Mobilization Act, 1940" (NRMA), which allowed the government to register men and women and move them into jobs considered necessary for wartime production. The act also allowed for conscription for the defence of Canada, but did not allow conscripts to be deployed for overseas service. The French-Canadian nationalist mayor of Montreal Camillien Houde in a speech urged all French-Canadian men not to register under the NRMA, which led the Dominion government to use the suspension of "habeas corpus" under the War Measures Act to send the RCMP in to arrest Houde, who was held without charge until 1944. From 1940 onward, the Defence Minister James Ralston and the Navy minister Angus MacDonald were seen as the advocates of the armed forces in the cabinet, favouring winning the war even at the price of domestic disunity vs. King who argued that domestic unity could not be fractured as the price for victory.
