The issue is a complex one because the 'Dunkin Act' of 1864, and later Canada Temperance Act of 1878, allowed for municipalities to hold referendums and prohibit the local sale of liquor (although liquor could still legally be mail-ordered or prescribed by doctors). 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). For the peoples of the First Nations and those legally labeled as "Indians" they were barred from alcohol under various legislation -- but again an exact date for the start of prohibition for all of Ontario is difficult to obtain.
