With deep sadness, we share the passing of Alexander (Alex) Temporale, Principal Emeritus of ATA Architects Inc. Alex was a leader within our firm and a devoted advocate for architecture, heritage conservation, and community building across Ontario.
Over his distinguished career spanning over 50 years, Alex combined his passion for design with an unwavering commitment to preserving our shared history. As a founding partner of Stark Temporale Architects in 1974, and later through ATA, he guided countless heritage studies, restoration projects, and revitalization initiatives. His work was instrumental in the creation of Ontario’s first Heritage Conservation District in Meadowvale Village and in the rehabilitation of several landmark buildings.
Alex was recognized with numerous awards, including the Lieutenant Governor’s Ontario Heritage Trust Award for Excellence in Conservation, the Heritage Canada Foundation Cornerstone Award, and distinctions from the Town of Oakville and the City of Mississauga. In 2007, he was named a Fellow of the Royal Architectural Institute of Canada—one of the profession’s highest honours.
Beyond his professional achievements, Alex was a generous mentor, lecturer, and volunteer. He gave his time to organizations including the Ontario Historical Society, Heritage Canada, Mississauga Heritage Foundation, and the Ontario Association of Architects’ Perspectives (now Right Angle) journal. Mayors and community leaders from across the province recognized his dedication to heritage preservation, describing him as both a gifted architect and an inspiring advocate for cultural heritage.
Alex will be remembered for his professional excellence and his warmth, generosity, and vision. His influence can be seen in the many buildings, districts, and communities that are richer for his care. Alex’s memory will forever be held in the heart of our firm and in the hearts of those of us who had the honour to know him.
We extend our heartfelt condolences to Alex’s family, friends, and all who had the privilege of knowing him. His legacy endures in the places he helped protect, the people he mentored, and the profession to which he gave so much.
