Toronto Office

RDH Toronto is our newest, yet fastest growing office. Our project staff are active in eastern Canada and the US, specializing in façade engineering, construction document risk review, energy modeling, retrofits for historic masonry buildings, and other building enclosure related services.

New Construction

From concept through construction, our New Construction team has established relationships and a reputation for excellence with local architects and developers on unique residential, commercial, and mixed-use buildings. Our building enclosure consulting and façade engineering services ensure that new buildings are constructed to withstand their environment while maintaining the original architectural vision. We also contribute to Toronto’s goals of building more energy-efficient structures by providing airtightness testing, thermal + hygrothermal simulation, and energy modeling services.


With research facilities located at Building Science Laboratories (BSL) in Waterloo and Vancouver, our capabilities for building science research and testing are unmatched in Canada. The most current data and findings are not only published and presented, but are also put to practical use in all of our work across North America, informing our decisions and advancing the field of building science.

Existing Buildings

For homeowners and property managers, our goal is to deliver expert solutions and advice to help you avoid surprises, save you time and effort, and provide you with peace of mind. If your building is experiencing performance issues, our team of engineers and technologists can complete whole-building investigations and condition assessments to find the source of the problem and make recommendations.

We can provide repair, renewal, or rehabilitation services for all parts of the building enclosure, and offer a construction project management approach that ensures your project is completed to the highest standards, on time, and on budget.

Our Energy team can assess your building’s energy use and provide guidance on energy saving opportunities, while our Maintenance and Planning team can work with you to develop strategies to manage your assets and prepare for the long- and short-term needs of your building.

Upcoming LAB Events

Our Waterloo office hosts monthly LAB (Learning About Building Science) events designed for architects, engineers, and anyone with an interest in building science. Our goal is to take high-quality research and building science principles and make them fun!
