Steam Whistle Brewing is a Micro-brewery located in the historic John Street Roundhouse in the heart of downtown Toronto, south of the CN Tower and Rogers Center. The brewery is home to two versatile loft-style event spaces that can accommodate up to 750 people. The architectural highlights of our space include large multi-paned windows, 30-foot ceilings, Douglas fir pillars and exposed red brick. By virtue of being located in a brewery, our atmosphere is relaxed and very friendly whether hosting a community fundraiser or a corporate social. All of these elements come together to create an extraordinary venue for your event.
