    20 YEARS: 20 GREATEST PROJECTS 13/20 The Norbec Manufacturing Facility in Strathroy represents a major investment in Ontario’s industrial capacity, expanding local production of insulated metal wall panels and strengthening Canada’s building materials supply chain. Our team provided full mechanical and electrical design services, developing systems that support reliable, efficient production across both the plant and the two-storey office. Each system was designed for durability, maintainability, and flexibility to meet the needs of a growing operation. Take a closer look at how engineering contributed to a key addition to Southwestern Ontario’s manufacturing landscape: 🔗 https://callidus.ca/callidus-engineering-turns-20/norbec-manufacturing/ #EngineeringExcellence #Strathroy #IndustrialEngineering ...

    What makes growth possible isn’t just the projects. It’s the people around you.In this clip, Electrical EIT Colter Roughley talks about the value of having a team that’s open, patient, and willing to teach. That kind of environment turns tough assignments into opportunities to learn something new. It builds confidence, trust, and real skill.That’s the kind of workplace we work hard to protect. A place where curiosity is welcome, and support is never out of reach.#EngineeringExcellence #LDNont #KWAwesome #YGK ...

    Walk into our London office on Tuesday this week and you would have found balloons, photos plastered everywhere, and even a life-size cut-out guarding one door. All of it for one reason: celebrating Callidus Engineering's founding principal, Grant Hall’s 40th anniversary as a professional engineer. Grant’s story is inseparable from ours. From starting J.E.D. Engineering at his own kitchen table to helping build Callidus Engineering into a team that now stretches across three Ontario cities, his fingerprints are on every chapter of our history. And as Callidus Engineering marks its 20th anniversary this year, the timing of Grant’s 40th makes the celebration all the more special, with both milestones arriving together in the same year. The messages from our staff paint a clear picture: a mentor who never hesitates to share knowledge, a leader who makes time for everyone, and a colleague who somehow blends technical precision with genuine kindness. The jokes and stories say a lot too, because you don’t end up with four decades of engineering memories without a few legendary moments along the way. Forty years is a milestone worth more than balloons and laughter, though we’ve had plenty of those this week. It is about recognizing the dedication, leadership, and generosity that brought Callidus Engineering to where it is today, and that continue to guide the next generation forward.
