At mcCallumSather, our purpose is clear – the design of a more resilient world through the advancement of sustainable design intelligence.
As an integrated team of sustainable design professionals, we embrace an inclusive approach to design that encourages curiosity and invention. As a result, each project reflects our commitment to design excellence and sustainable design solutions, coupled with a relentless focus on our client’s goals. Led by this spirit of innovation, we continuously strive to communicate better, design more efficiently and deliver improved experiences.
We recognize the strength of an integrated team. It led to our decision to offer in-house mechanical engineering and interior design services, in addition to our architecture offerings. We did this to facilitate comprehensive service on small renovation projects and improve coordination and system integration on larger projects. LEED Facilitation, Laboratory Design and Heritage Consultation strengthen our service and help us deliver specialized, tailored solutions.

Transforming design to create a more resilient world
Where we've come from
Joanne McCallum and Greg Sather founded mcCallumSather in 1996. Now, with over twenty years of experience, our firm has achieved an impressive record of significant industry firsts. Our portfolio includes an exciting mix of award-winning work throughout Southern Ontario, from heritage to new construction, small community initiatives to multi-million-dollar, one-of-a-kind projects.
Amongst our accomplishments, we designed the first LEED Gold Certified project under the CaGBC, the Region of Waterloo EMS Facility; the first building in Canada to gain CaGBC Zero Carbon Building Standard Certification in both design and performance categories, the Joyce Centre for Partnership & Innovation; the largest LiveLab of its kind and one-of-a-kind research facility designed for the study of how music and movement impact our health, McMaster Institute for Music and the Mind; and design of the only open-access full scale press and manufacturing equipment of its kind to be installed in North America, Western University’s Fraunhofer Centre.
The communities we call home
We design engaging environments that transform communities. Therefore, it’s important to us that we are involved in Hamilton and Kincardine, including many initiatives that strengthen our neighbourhoods and our profession. Learn More
