Steam Whistle Brewing

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 bought out. The company produces only one style of its own beer, a Premium Pilsner. The company also produces New Belgium Brewing Company brands for the Canadian market.

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.

The company operates the annual Steam Whistle's Roundhouse Winter Craft Beer Festival (RHCBF).

The brewery was the first customer of renewable energy project, the Deep Lake Water Cooling System.
