 During the early 1940s—when bars in Ontario closed at 1 am and bars in Quebec closed at 3 am—residents of Ontario continued to take advantage of Quebec's more liberal policies on alcohol control.An official inquiry in the 1940s found that gambling houses and illegal bars in Hull were receiving protection from corrupt local politicians, who also encouraged police not to arrest prostitutes.During World War II, Hull, along with various other regions within Canada, such as the Saguenay, Lac Saint-Jean, and Île Sainte-Hélène, had Prisoner-of-war camps.
