In 1955, Columbia’s founder Len Corcoran set out to manufacture the best skylights for the Canadian market. Today, we continue to fulfill his dream, as the largest manufacturer in Canada – due to our tradition of advanced engineering, product innovation, quality craftsmanship, and prompt, courteous service.
Columbia manufactures a wide range of fixed and venting skylights, in glass and acrylic, standard or custom sizes. Including the widest range of ENERGY STAR® certified models.
Columbia offers an extensive range of residential and commercial Sun Tubes. Ideal for bringing natural light into smaller areas in your home, or a commercial building.
Slimlite is part of the Columbia Group of Companies, manufacturing exceptional commercial and residential skylights.
Columbia is the exclusive Canadian distributor of premium European FAKRO Skylights, Roof Windows, & Flat Roof Skylights.
Columbia has grown to become one of North America’s leading producers of commercial and residential skylight systems.
Over 1 million Columbia skylights have been installed on North American homes and businesses since 1955.
We have proudly distributed our skylights around the globe – from North America, to Europe, to Asia.
Columbia is dedicated to manufacturing high quality energy efficient skylights, with the industry’s most complete product line, at the most competitive price, while offering a superior level of service to our valued customers.
Use the finest quality raw materials and partner with the top suppliers in the industry to ensure that each skylight we produce meets the highest standards.

A unique set of values has directed us since we started the business. They are our North Star, guiding us every day to pursue excellence. They are as important to us today as they were the day we opened for business.
We deliver our high quality products to our customers with confidence, knowing they will serve them well for decades to come. Nothing fills us with more pride than seeing our products on a Canadian home or business.
We never sit still and are always looking for the best solution.
This drives us to embrace new technologies, processes and operational efficiencies in order to deliver better products and services to our customers.
From the manufacturing processes, the materials we use, and the suppliers we partner with – the highest level of quality is essential.
Our industry leading warranty is our commitment behind our high standards.
You can never have enough passion for what you do.
We infuse this energy inwardly through our engaging and rewarding work environment and then externally to our retail and professional partners, and customers.

We are proud to participate in LEED certified projects, reducing our waste and environmental footprint, as well as being good stewards and supporters of environmentally focused initiatives.
We thank our team who work hard every day to make Columbia better. Without the experience, dedication and commitment of our employees Columbia would not be able to produce the high performance quality skylights it is known for.
Columbia has always been a family. It has been our goal to treat our employees with respect and gratitude. Many of our employees have been with us for decades, some spending their entire career with us.
Our culture is one of integrity, and inclusiveness. We work as a team, embracing innovative ideas that have come directly from the manufacturing floor.
