About the TSA

Established in 1887, the Toronto Society of Architects (TSA) is a non-profit volunteer-based organization comprised of architects, professionals from sister organizations, and members of the community interested in architecture and urban issues. The TSA is the local Chapter of the Ontario Association of Architects (OAA), which is the licensing and regulatory body that governs the practice of architecture in Ontario.

The TSA plays an advocacy role in the City, ensuring that architecture and design are key considerations in public discussions and in processes that have an impact on our built environment. The TSA has effectively lobbied civic governments, participated in civic improvement roundtables, hosted public forums on current city planning issues, and initiated discourse on urban and architectural concerns in the city.

The TSA organizes and sponsors a wide variety of initiatives including forums, exhibitions, publications, competitions, film series and celebrations that engage the architectural profession, its sister disciplines, and the public. The TSA Executive, comprised of volunteers, undertakes and directs these initiatives throughout the year. We strive to promote and advance the role of architecture and design in Toronto’s dynamic community.
