About Us
Reshaping how buildings get built
At Moses Structural Engineers, we bring together deep experience across mass timber, hybrid systems, prefabrication, and net-zero design—then combine the practices to engineer smarter structures. Our breadth of knowledge is rare, and it has led to groundbreaking design and multiple Canadian firsts.
We approach every project as an opportunity to design better—from geometry and materials to code and constructability. This thinking has unearthed new approaches, cleaner details, and groundbreaking designs that continue to move the industry forward.
One of our core values is lasting impact. We take pride in ushering Canada toward smarter, lower-carbon construction while ensuring every client feels supported along the way. You have our time, our attention, and our respect. And we don’t just deliver drawings—we help navigate what’s possible, permitted, and proven to perform.

We’re on a mission
We are educators and advocates for the future of building. We lead research with universities, contribute to national guidelines, speak at conferences and mentor the next generation through TimberFever. We do this because building smarter means sharing what we know.
Meet Our Team
Our leadership team brings deep experience across structural systems, project types, and delivery models. From tall wood towers to modular housing prototypes, we’ve helped lead Canada’s shift toward smarter, faster, lower-carbon construction. As engineers, collaborators, and mentors, we stay personally involved in the work—bringing technical clarity, code insight, and continuity from concept to completion.
David Moses | PhD, PEng, PE, LEED®APPrincipal (416) 255-3337 ext. 2000David is one of Canada’s foremost leaders in timber structures, heavy timber, glulam and CLT, and an advocate for advances in structural engineering and industry standards. His extensive portfolio includes the first Canadian CLT and passive house buildings and the Art Gallery of Ontario renovation—at the time one of the most sophisticated wood structure in North America, as well as three prestigious professional awards. The firm’s genuine nature, passion for projects and attention to detail are driven by David.

"Having a PhD makes one very aware of all the things we don’t know. This means we’re always searching for new answers, new solutions. As a result, our work is always fresh.”
