In mid-August 1943, Winston Churchill came to Canada to attend the Quebec Conference, a then-secret meeting in Quebec City to discuss a strategy for the invasion of France during World War II (which would come to be known as D-Day). Prior to the conference, he met with William Lyon Mackenzie King several times. Between the meetings and conference, Churchill visited Niagara Falls and was driven along the Niagara Parkway, after which he described it as "the prettiest Sunday afternoon drive in the world."
