The Dominion Alliance for the Total Suppression of the Liquor Traffic was an organization established in 1877 in Canada that lobbied for prohibition of alcohol.

The Dominion Alliance faced passive resistance from politicians concerned about the views of their constituents, particularly in Quebec, but had some success at the local level.

The council met in Ottawa in 1876 and decided to found the Dominion Alliance for the Total Suppression of the Liquor Traffic, which was established the next year.

[3] In 1901 the Privy Council ruled that federal legislation applied to manufacture and import of intoxicating liquor, but the retail trade was regulated provincially.

[4] Members included mainly English-speaking Protestant organizations such as WCTU and YMCA branches, Salvation Army Corps and Baptist Young People's Unions.

[6] The Dominion alliance produced books, pamphlets and flyers, organized meetings and backed temperance laws at all levels of government.

[7] In 1902 George William Ross, a member of the Dominion Alliance and premier of Ontario, passed legislation banning sale of alcohol subject to ratification by a large majority in a referendum.

Spence helped direct initiatives at the local level in Ontario, gaining support for the prohibitionist policies of Ross's successor James Whitney.

[7] In 1915 the Dominion Alliance began working with the federal and Ontario governments to treat prohibition as a part of the war effort.
