The Calder Group markets and manages industrial real estate offerings in Southwestern Ontario, with a focus on large warehouse/industrial space and industrial land arrangements. The company’s website positions its availability and leasing approach around an “all-inclusive” package model and highlights activity in the Kitchener–Cambridge–Guelph area. A public contact listing identifies Mike Claydon as a primary point of contact and provides an office phone number and Cambridge address. Public business-directory references associate The Calder Group with the legal name D5D Enterprises and place headquarters at the same Cambridge location. A founding year and public ticker are not indicated in the sources reviewed; based on the absence of public-market references, the company appears to be privately held.
