Our Team
Charles Marshall Partner, Engineer, Toronto Studio Chair BASc | MBA | PEng | LEED® AP Toronto

Charles joined our team a decade ago and immediately started pushing the limits of our sustainability and building performance work. Leading project teams across Canada, he has set ambitious targets and exceeded project goals for environmental sustainability and community wellbeing. With a background in mechanical engineering, Charles always stays grounded in the technical details of his project work. He encourages his teams to innovate and explore new ways of reducing energy use and carbon emissions. Charles has been a core contributor to some of our most exciting sustainability projects, breaking through barriers in net-zero energy and carbon-neutral design. 

Charles is a firm believer that the transition to a low-carbon economy requires design thinking as well as solutions to inherent social, economic, and financial challenges. The conviction that development with a purpose is essential to delivering the highest returns and sustainable performance drives his work. Charles is always ready to help our clients approach problems from a business and financial mindset, so the right questions are asked, and the best solutions are uncovered.  As someone who brings dedication, openness, and a can-do attitude to his design and advocacy work, he is committed to finding solutions to climate change and environmental issues that also increase the health and wellbeing of our communities. 

What’s your favourite DIALOG initiative?
I have to say that it’s our AIA 2030 Commitment to drive all of our project work to a carbon-neutral level of performance. I love that we have taken this stance and are demonstrating action in the face of climate change issues. It energizes me to think about how we will advocate to our clients to design their buildings to carbon neutral in sectors where this is far from the norm.
