Hiram Walker-Gooderham & Worts Limited

In 1837, William Gooderham (1790-1881) established Toronto’s first permanent distillery at the mouth of the Don River, using surplus grain from the milling business he had started with business partner James Worts (ca. 1792-1834).

The Gooderham family's expertise making beer and whiskey made them the wealthiest family in Ontario. The five-storey, limestone mill and distillery, designed by David Roberts Sr, opened in early 1861, increasing production capacity from 80 000 to two million gallons per year (303 000 litres to 7.6 megalitres). Roberts and his son would go on to design nearly all of the distillery buildings, one of the major reasons for the harmony of the site, as well as the distinctive Gooderham flatiron building and the family mansion.

Whiskey distilling was interrupted during the First World War for the production of acetone, and the business was sold to Hiram Walker in 1926.
