ATIS Group is one of the leading windows and doors manufacturers, distributors and retailers in Canada.

Over the past 70 years, we have acquired a solid reputation due to the excellence of our products and service. In 2020, the Group is launching the ATIS banner, bringing together all its stores and the majority of its products under the same name.


We believe the doors and windows purchasing process can be simple, user-friendly and efficient. This approach is applied in all the projects we undertake, whether with individuals, construction contractors or real estate developers. Several recognized corporate buyers have chosen our products for large-scale mandates, including hotels, highrise housing projects and commercial buildings.
