With nearly 60 years as a leading high voltage electrical service provider and electrical rubber goods supplier, LTL has successfully diversified and expanded to become one of the foremost distributors of quality industry-related products. Over the last ten years, LTL Utility Supply (“LTL”) has aggressively expanded its product distribution across Canada to include pole line equipment and electrical apparatus. This equipment includes, but is not limited to, anchors, cable brackets and supports, connectors, guy wire, grounding equipment, splices and terminations, insulators, standoff brackets, switches, fiberglass hardware, and wire and cable.
Distribution Centres are centrally located in Ontario and Alberta allowing for coast-to-coast coverage and timely deliveries to our customers. Conveniently located near Toronto Pearson International Airport, our 53,000 square feet Toronto Distribution Centre accommodates large equipment inventory and boasts five shipping and receiving bays. LTL’s recent move to a larger facility in Edmonton is testament to our ongoing expansion in the West.
LTL Utility Supply’s rapid growth is due in part to LTL’s commitment to reliability, exceptional customer service, extensive inventory and a strong team consisting of knowledgeable sales representatives. LTL’s team includes industry-experienced inside and outside sales product specialists – several of whom are certified journeymen-linemen by trade, degreed business personnel, electrical engineers and technologists, master electricians, laboratory technicians, and factory-authorized repair technicians.
LTL continues to gain market share. Our uniqueness is in our ability to respond quickly to our customer requests for both standard and hard to find products, doing whatever it takes to satisfy our customer requirements – not seen with larger, multi-national companies. LTL’s adeptness at building and maintaining business relationships has allowed us to purchase these products directly through a vast network of leading manufacturers. Because we partner with the manufacturers we represent and commit to inventory of their product, our customers benefit from readily-available product.
