The wait is finally over. After a 2 year hiatus, the TSA BASH—Toronto’s architectural community's biggest celebration—is back!
A long-established tradition, the Toronto Society of Architects' annual year-end BASH is an opportunity for the GTA’s architecture and design community to come together and celebrate in unique spaces across our city. No two years are alike, with a new featured venue chosen every year and the party tailored to reflect the design stories behind the building. Great food, delicious drinks, and beautiful architecture—there is no better way to celebrate our city and those who shape it!

This Year's Venue: John Street Roundhouse:
The return of a landmark party deserves a landmark venue. For 2022 we are excited to be bringing the party to a hub bridging our city’s past and future: John Street Roundhouse!
Built in 1929 by the Canadian Pacific Railway, this uniquely shaped facility once provided servicing and light repairs to passenger steam locomotives used at nearby Union Station. Divided into individual stalls, the roundhouse could serve 32 locomotives at any time which were moved in and out of the structure on a massive rotating turntable. Remaining largely empty for over a decade after its closure in 1986, this National Historic Site is now exemplary of adaptive reuse—the heritage structure carefully tuned to host a brewery, event space, restaurant, and a railway museum, while the surrounding yards have been converted into a new downtown park. The revitalization efforts were led by architect Donald J. Loucks employed as a Senior Associate of IBI Group.

Learn more about this building’s rehabilitation and reuse story directly from the architect in this short video hosted by the Toronto Railway Museum.

*What TSA event would be complete without a tour? Come for the first hour of the BASH and join us on a tour exploring the past and present of this year’s venue!
Our tours will start with a ride on the roundhouse’s massive 36.5m long rotating restored turntable which was used to position locomotives into their stalls. Volunteers of the Toronto Railway Museum will share with us the history behind this structure, its former use, and how it all works. After your ride, we’ll bridge the building’s past with its present as the tour continues with short walk with architect Donald J. Loucks, who led the revitalization efforts of the Roundhouse.

The tours will start at 6:00 PM, 6:30 PM, and 7:00 PM. Tours are open to all ticket holders but limited space is available. Spots will be filled up on a first come, first serve basis.
