The Illuminating Engineering Society of North America (IES) is the recognized technical authority on illumination. For over 100 years; its objective has been to communicate information on all aspects of good lighting practice to its members, to the lighting community, and to consumers, through a variety of programs, publications, and services. IES is a forum for the exchange of ideas and information, and a vehicle for its members' professional development and recognition.

Through technical committees, with hundreds of qualified individuals from the lighting and user communities, IES correlates research, investigations, and discussions to guide lighting professionals and laypersons via consensus-based lighting recommendations. The Society publishes nearly 100 varied technical publications and works cooperatively with related organizations on a variety of programs and in the production of jointly published documents and standards. Local IES Sections and many lighting corporations offer formal educational programs on lighting, utilizing material developed by IES. Sections offer programs related to specific applications based on IES standards - seminars on sports and recreational lighting, lighting industrial facilities, roadway lighting, museum lighting, to name a few. Virtually every curriculum devoted to lighting - from beginner to advanced - includes IES educational materials.

The IES is almost 10,000 members strong. Its members work with lighting in a variety of capacities - lighting designers, architects, interior designers, government & utility personnel, engineers, contractors, manufacturers, distributors, researchers and educators - throughout the United States, Canada, Mexico - and around the world. They share a common interest in lighting, and a common desire to promote the use of the latest, most innovative lighting technologies, with a focus on judicious use of energy in all lighting applications.

The Ottawa Section received its charter from the Society in 1943.

It began during the height of World War II. Even amidst the turmoil of the conflict, a group of dedicated lighting practitioners felt a need to meet to share best practices and stay on top of the many developments of emerging lighting technologies. At that time, Linear fluorescents were a new product, having been introduced to the world at the 1939 World's Fair in New York. 

As for lighting in Ottawa, our local Section has provided our members and others interested in lighting quality a forum to share ideas through guest speaker presentations and the delivery of lighting education. Our member enjoy opportunities to meet and network with like-minded individuals with whom they share best practices and lessons learned.

Since Warren (Monty) Montabone served as the first president of our Section he has been succeeded by 54 others, all of whom have contributed to shaping the local lighting landscape. View the  list of past presidents
