Steam Whistle Brewing is an independent brewery in Toronto, Ontario, Canada. It was founded in 2000 by three former employees of Upper Canada Brewing Company after that company was acquired by a larger corporation.[1] Steam Whistle is best known for producing a single flagship beer, Steam Whistle Pilsner,[2] which has become one of Canada's most recognized independent beers. The company also produces New Belgium Brewing Company brands for the Canadian market.[2]
The brewery occupies Bays 1–14 in the John Street Roundhouse building at Roundhouse Park. Built in 1929, it was previously the home of a Canadian Pacific Railway steam locomotive repair facility and operated as such until May 13, 1988. The John Street Roundhouse is designated a National Historic Site and is owned by the City of Toronto.
