Northern Breweries was a brewing company with facilities throughout Northern Ontario. The company was established in Sudbury in 1907 as Sudbury Brewing and Malting Co. by J. J. Doran, a hotelier. On August 31, 1971 the company was purchased by Canadian Breweries, but it continued to operate under the name Doran's Northern Breweries. In the late seventies employees purchased the company back from Canadian Breweries, and Northern became the first employee owned brewing co-operative in North America. After ownership changes in 2004 the company announced a major rebranding effort, retiring many of its old products in favour of more modern brews and brand identities. In 2006 the company was $7 million in debt and ceased production at the Sudbury facility.
The company's facility in Sudbury was acquired in 2010 by Sookram Bus Lines.
