The viceregal couple also played host at Quebec City to prime minister Mackenzie King, as well as Churchill and United States president Franklin D. Roosevelt, who all gathered to take part in what would become known as the Quebec Conferences, with the first taking place between 17 and 24 August 1943 at the viceregal residence in La Citadelle, and the second occurring from 12 to 16 September 1944 at the Château Frontenac. Photos of the Earl with Roosevelt, Churchill and Mackenzie King on the ramparts of the Citadel during the Quebec Conference were widely published at the time.
