From the introduction: Canada and the United States have a history that is deeply intertwined and very long a shared border. Some readers may be unaware that the then Dominion of Canada in the 1920s also had prohibition laws and that much of the country was actually dry. During the years of prohibition enforcement in both Canada and the United states an unintentional consequence of prohibition legislation in both countries was that liquor was smuggled across the border from Canada into the United States. Neither country were able to successfully check the demand for illegal liquor or its smuggling. Moreover, prohibition’s illegal profits soon provided the money to fuel the start of organized crime.
