Dominion Police
The Dominion Police, although the federal police of Canada, was mainly active in the Eastern Canada region, while the Royal Northwest Mounted Police handled the expansive and sparsely populated Northwest Territories of Western Canada. In May 1918, the 969-member Dominion Police was reassigned under the Department of Militia and Defence and became a civilian wing of the Canadian Military Police Corps (CMPC). In the early 1900s, the Royal Northwest Mounted Police had declined as the Northwest Territories was divided into new provinces and territories, and due to the general unpopularity of the force for conduct during industrial disputes such as the Winnipeg General Strike. On 1 February 1920, the civilian members of the CMPC, including the Dominion Police, were merged with the Royal Northwest Mounted Police to form the Royal Canadian Mounted Police as the new federal police force of Canada, and the CMPC was disbanded on 1 December 1920.
The Royal Canadian Mounted Police in Quebec
RCMP participation was required in numerous events of major importance that took place in the Province of Quebec, as the responsibilities of the Force include protecting VIPs during their visits to Canada and providing assistance to other police departments in the province during major events. 
In 1943, as the Second World War was raging in Europe, US and Canadian troops joined their European allies on the front lines. Since 1939, the two heads of state have held five conferences for the purpose of developing strategies to defeat the enemy’s devastating offensive. They chose Québec City for their sixth conference. So from August 17 to 24, 1943, US President Franklin Delano Roosevelt and British Prime Minister Winston Churchill met within the walls of this fortified town for the Québec Conference, hosted by Canadian Prime Minister William Lyon Mackenzie King. Along with high-ranking officers of their respective armies, they planned military operations that led to the Allied victory over Axis forces.
