About Us

Serving your Residential and Commercial Engineering needs since 2008.


Edison was founded in 2008 by Jason Truman, a family descendent of the famous inventor and entrepreneur Thomas Edison, for whom the firm is named. It is not well known in Canada that the Edison family, lead by Thomas’ grandfather, settled in Ontario south of London after the War of 1812. The Truman family patriarch also settled in same area in 1818, and by circa 1843 a Truman and an Edison had married.

Our first office was located in the historic town of Dundas, Ontario. In 2013 Edison welcomed its first partner, Stéphan Trépanier, and opened an office in Unionville, Ontario. The partnership with Stephan strengthened Edison’s leadership and engineering expertise and allowed us to improve service to our growing client base in the Greater Toronto Area.

Our focus was on the repair and restoration of the building structure and envelope. Building performance issues, such as operating costs and resident comfort, are affected by the interplay of the building envelope and mechanical systems. To provide Owners and Managers with a more holistic approach Edison created a Mechanical, Electrical and Energy (MEE) business unit in 2014. Our Clients leverage this in-house expertise to help them make informed decisions to optimize building performance and assess their energy systems.

In 2014 Edison also expanded its service to include a Special Structural Repairs and Renovations business unit. Structural services allows Edison to efficiently support our Restoration projects and provides our clients with a resource for unique Structural projects on existing buildings.

In addition to offices in Hamilton and Toronto, we began serving a growing client base in southwestern Ontario from offices in Windsor (2014), lead by Stefan Nespoli, and in London (2016) lead by Raj Jain. The addition of Raj strengthens our team’s leadership and expertise.

At Edison Engineers we strive to exemplify the foundation of hard work and creativity for which the great Thomas A. Edison was renowned. We pride ourselves on educating engaging and empowering our clients in their projects!


We are committed to delivering customized and pragmatic engineering services. We develop and sustain long term relationships built on trust and reliability, we adapt our services and solutions to the objectives and financial constraints of our clients, and we strive to create a rewarding workplace for our team to help us in delivering the best quality service!


We proactively educate, engage, and empower our clients in their projects to help them develop and deliver informed strategies for their building assets. We actively drive projects to successful completion on time and within budget, we demand quality from contractors, and we consistently and clearly communicate with our clients and all project stakeholders.


Professional Engineers, Deep Client Partnerships

Edison offers a deep knowledge of building assessment and repair expertise to the challenges our clients face. We help building owners leverage our expertise by presenting complex problems in easily understood formats and by introducing many available options for consideration. Our clients are well informed, educated and feel confident when making important decisions that impact their buildings or the buildings they manage.

Edison enjoys working in deep partnership with our clients, viewing their success as our own. Working together, we create better results than either of us could alone.



Integrity is defined as “uprightness of character; honesty”. This quality is the foundation of all we do and of how we deliver services to our clients. We are guided by a long term perspective and present advice and recommendations that we can openly defend and support. We share our objective findings with clients—even those that may be unpopular—in a manner that is both candid and respectful.

We carry out our services in accordance with our statutory duties as engineers under the Professional Engineers Act. We serve and protect our client’s interest where engineering is concerned. We are rigorously educated, experienced and committed to a Code of Ethics that puts our clients first. We observe appropriate confidentiality of client information. We do not misrepresent our purposes in seeking information. We only make promises we can keep.

Clients Come First

We measure our success by our clients' success. We make all our resources available to our clients and commit ourselves wholeheartedly to their success. We seek to identify our clients' real needs, not just deliver good work. In tradeoffs between Edison’s and a client's interest, the client comes first.

Valuable Solutions

We are problem solvers. We are committed to creating valuable solutions to our client’s building problems. At Edison, we design pragmatic solutions based on a deep understanding of our client’s goals and financial objectives or investment strategies, not simply presenting solutions we “think” are right.

We set our standard for creating valuable solutions extremely high. Creating valuable solutions to our client’s issues requires a depth of engineering knowledge and expertise and an ability to present the information simply and clearly. Our work must lead directly to our clients understanding the issues so they can confidently take action and execute projects to improve their properties.

We hold ourselves accountable to providing valuable solutions by engaging candidly with clients about the quality of our work.

Our Team

Put our highly energized and engaged Team to work on your projects. Working together we can accomplish more than we can individually.
