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).
In December 1917 Congress adopted and submitted to the states the Eighteenth Amendment, known as the Prohibition amendment, which prohibited the manufacture, sale, or transportation of intoxicating liquors.. Ratified by the states in January 1919, it went into effect on January 20, 1920.
