We invite you to call or visit a Watson location today.


From our humble beginnings in 1968 at a single location in Concord, Ontario, Watson Building Supplies has grown to 5 locations with over 220 dedicated employees and a fleet of over 70 commercial delivery trucks. As the industry leader in the markets we serve, we continually strive to exceed our customers' expectations with unparalleled service, quality, safety, and the widest product offerings in our business.

In 2009 Watson joined forces with Shoemaker Drywall in western Canada and EB Beauchesne in Quebec and eastern Ontario to form WSB Titan. In doing so, we established Canada's largest privately owned and operated drywall, steel framing and insulation supplier. Through WSB Titan we'll continue to offer our customers new product lines and services and partner with Canada's top product manufacturers to provide the best brands in the industry.

At Watson we value our relationships with our customers and suppliers and are proud of our
National Strength and a Local Commitment.
