Grandor Lumber is Ottawa's division of the Alpa Lumber Group, drawing on more than 50 years of Ontario manufacturing experience to supply the capital's home builders, contractors and renovators from its Bank Street yard. We carry framing and dimensional lumber, engineered wood products like LVL and I-joists, doors, and roof trusses designed and manufactured within our own local facilities rather than outsourced, so your structural package and framing stock come from one accountable source. Professional sales and technical staff work from your plans to spec the right materials for the job, and we focus on the residential new-construction market that drives Ottawa's growth. Backed by the scale and engineering of a vertically integrated lumber group but operating as your local Ottawa yard, Grandor pairs big-supplier capability with hands-on service. For builders who want lumber, engineered wood and trusses from one established Ottawa source, Grandor delivers.
