Sleeman Breweries is a Japanese-owned Canadian brewery founded by John Warren Sleeman in 1988 in Guelph, Ontario. The company is the third-largest brewing company in Canada. Along with its own Sleeman brands, the company produces under licence the Stroh's family of brands, Maclays Ale and Sapporo Premium beers for sale in Canada. The company's parent Sapporo owns 4.2 per cent of Ontario's primary beer retailer The Beer Store. The company is the re-establishment of a line of brewing companies owned by the Sleeman family dating back to the 1830s. The original Sleeman Breweries was established in the 1850s and operated until it lost its licence due to smuggling and tax evasion, for 50 years, in 1933. John W. Sleeman re-established the brewery in the 1980s using the original company recipes. In 2006, Sleeman Breweries was purchased by Sapporo Brewery for million. John W. Sleeman remained as CEO until 2010 when he relinquished that role and was made Chairman of the company. History John H.

He and his family moved to Guelph in 1847 where they operated a series of breweries including the Hodgert’s Brewery, and the Silver Creek Brewery, which he opened in 1851. His son George Sleeman joined the company in 1859 as general manager and was named a partner in 1865. John H. died in 1893. By 1890, George Sleeman had achieved great success with Silver Creek Brewery which had sales in Ontario and Quebec. He incorporated it into the Sleeman Brewing and Malting Company Limited with members of his immediate family. Due to excessive investments in his Guelph Street Railway Company, he lost the businesses to the banks in 1905; he then opened the Springbank Brewery. A year later the banks sold the brewery back to Sleeman. The family subsequently operated breweries in Guelph, often with success, until 1933. Prohibition in Canada had an effect on the business. In Ontario, prohibition started in 1916 with the passing of the Ontario Temperance Act by the Government of Ontario. While that eliminated the domestic market, the law allowed for brewing for export, so the Sleemans continued to do so, shipping their products to the US. This was perfectly legal until 1920 when the Volstead Act led
