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.
