In Ontario, the Ontario Temperance Act of 1916 enacted prohibition as of that year and an Order in Council by the Government of Canada made the manufacture of spirits anywhere in the Dominion illegal in March 1918 (however this only lasted twenty-one months, ending in December 1919).
Prohibition in the United States was a nationwide constitutional ban on the sale, production, importation, and transportation of alcoholic beverages that remained in place from 1920 to 1933.
