We are proud to serve a long-standing client base that includes private clients, municipalities, school boards, post-secondary institutions, and cultural organizations.

Our approach is collaborative, transparent, and driven by a passion for meaningful architecture that responds to place, history, and purpose.

With recognized leadership in BIM, ecological design, and building envelope technologies, we create spaces that are not only beautiful and accessible but resilient for future generations. At ATA, architecture is not just about buildings—it’s about shaping enduring environments where people can Aspire, Transform and Achieve.
