What we do

Founded in 1889, the Ontario Association of Architects (OAA) is an independent regulatory body that serves and protects the public interest by overseeing the architectural profession in Ontario, as mandated by the Architects Act. The Association licenses Architects and Licensed Technologists (OAA members), establishes and enforces standards for professional practice and ethics, and ensures ongoing education to maintain competency. By upholding stringent qualification standards and supporting continuous professional development, the OAA helps ensure its members create safe, accessible, and functional buildings that meet the needs of a diverse society.

Through the accountability the OAA requires and the guidance it provides to its members, the Ontario Association of Architects helps shape sustainable, vibrant, and resilient communities across the province. In its commitment to fairness, responsive regulation, and the protection of the public interest, the OAA inspires excellence in architecture that serves society.

At the end of 2023, there were 4,924 Architects and 1,961 practices in Ontario. Additionally, 1,991 Intern Architects, 624 Student Associates, and 236 Retired Members held status with the OAA.
