Established in 1887, the Toronto Society of Architects (TSA) is a non-profit volunteer-led organization dedicated to bringing people together to discuss, learn and explore around our shared passion for the built environment.

We are committed to the betterment of our city and have played an important advocacy role throughout Toronto’s history. We do this through a wide range of programs which foster welcoming and inclusive forums for debate and the exchange of ideas, stimulating critical thinking about the design and building issues of our time.

Our public programming is complemented by initiatives supporting the personal growth and professional development of over 2500 TSA members. Membership is open to everyone and welcomes design professionals, students and the general public.

The TSA is a Society of the Ontario Association of Architects (OAA), which is the licensing and regulatory body that governs the practice of architecture in Ontario.


Shaped by the needs and priorities of our community and urban region, the TSA offers a wide variety of year-round events and programs including lectures, networking events, tours, and workshops. Each initiative is unique and made possible thanks to the dedication of over 200 volunteers. Underlying all these events is our commitment to providing accessible, affordable and timely opportunities for both industry professionals and the public to engage with the architectural and urban issues of our time, build community, and raise awareness about our built environment.  Many of our events are done in partnership with like-minded organizations, and we often work with other groups and individuals to help develop their own ideas and initiatives.

What We Believe

We believe that city-building is a collaborative process strengthened by a diversity of voices, open debate of ideas, and an informed citizenship. Our work exists at the intersection of public and professional discourse, creating common ground for discussion. We believe in life-long learning, helping our members deliver better work for their communities and promoting civic literacy on architecture and design through engaging and accessible programming. We are committed to constantly evaluating our offerings to ensure their continued relevance, responding to changing needs and priorities.

We actively work to create an inclusive and welcoming Society, removing barriers to participation and supporting members throughout their careers. We believe in the importance of diverse viewpoints, emerging voices and untold stories. We work together towards common goals, providing platforms for the sharing of knowledge, experience and ideas.
