American ex-pat Hiram Walker built the Walkerville Distillery in Windsor Ontario in 1858 and began selling his 'Hiram Walker's Club Whisky' in the finer Detroit Gentlemen's Clubs shortly thereafter. The popularity of his whisky angered American producers - who banded together and forced the US government to pass a law requiring the country of origin be placed on the labels of all non-American whiskies. Hence the name 'Canadian Club' was born.
