Our History

Our humble beginnings stretch back to 1926. We started out as a single janitorial company in central Canada, but over time we expanded across the country from coast to coast and into the United States. We now have over 20,000 dedicated GDI employees servicing a variety of hotels, shopping centres, food plants, industrial facilities, airports, and other buildings, facilities, and establishments. While we now serve markets across North America and continue to grow and evolve as a company, we pride ourselves on remaining close to our clients. We combine national reach with a local touch to ensure you get the best value, dedicated attention, and a job done right the first time — every time.
