A voucher is a bond of the redeemable transaction type which is worth a certain monetary value and which may be spent only for specific reasons or on specific goods. Examples include (but are not limited to) housing, travel, and food vouchers.
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 was a period of nearly 14 years of U.S. history (1920 to 1933) in which the manufacture, sale, and transportation of intoxicating liquor was made illegal. It was a time characterized by speakeasies, glamor, and gangsters and a period of time in which even the average citizen broke the law.
