Dow Breweries was a brewery based in the province of Quebec, Canada. The company was founded by William Dow (1800–1868).[1] The Dow Brewery eventually came under the control of National Breweries of Quebec in the 1920s, which itself was bought out in 1952 by Canadian Breweries. After Canadian Breweries became Carling O'Keefe and merged with Molson Breweries, its brands were discontinued in 1997.
