ECI strengthens capabilities via acquisition
ECI Technology Group Acquires Questek, Significantly Expanding Capabilities and Production Capacity
ECI Technology Group Inc. has acquired Questek Manufacturing Corp., a 40-year-old maker of wire harness assemblies and electronic components based in Elgin, Illinois, AP News reported on June 30, 2026. The deal expands ECI's footprint into the U.S. Midwest and gives it immediate access to Questek's client base, which includes names like Navistar, Winnebago, and Sony.
ECI CEO Jash Patel called the move "an exciting and natural step forward," saying both companies would work together to "deliver more value" to customers worldwide, according to National Post. Questek's roughly 60,000-square-foot Elgin facility will keep running under the Questek brand name, and all current Questek employees are expected to stay on.
What Questek Brings to the Table
Questek was founded in 1987 and has spent nearly four decades solving what it calls "complex electronic problems," according to Montreal Gazette. The company makes wire and harness assemblies, control boxes, panels, and electromechanical parts. It moved into its current Elgin facility in 2000. That building can expand from 60,000 to 110,000 square feet, leaving room to grow.
Questek's clients span several industries — commercial trucks, recreational vehicles, office equipment, and industrial lighting. That customer mix gives ECI a ready-made foothold in markets it did not previously serve at scale, according to Edmonton Sun.
ECI Builds a Bridge Between Canada, the U.S., and Mexico
Before this deal, ECI ran facilities in Ontario — including sites in Tillsonburg and Burlington — and in Mexico, in the cities of Juarez and Chihuahua. Adding the Elgin, Illinois location creates what analysts describe as a "Midwest hub" linking those two halves of ECI's North American network, according to Sault Star.
The move fits a broader industry trend. North American manufacturers have been buying local plants to keep supply chains close to home and away from global disruptions. Questek's specialized, high-mix production model — meaning it handles many different product types in moderate volumes — made it a strong match for ECI's own design-through-production service model, according to Owen Sound Sun Times.
Questek's President Promises Stability for Staff and Clients
Questek President Dale Krueger said employees, customers, and partners "will benefit from the combined experience and expanded opportunities that this partnership brings," according to Goderich Signal Star. Krueger is expected to stay involved through the transition period. Retaining all current staff was a stated priority for both sides of the deal.
Keeping the Questek brand alive is a deliberate choice. ECI is treating Questek as a separate brand within its larger group — a strategy companies use when they want to protect a name that already carries weight with key clients. Dissolving the Questek name could have spooked long-standing customers who have worked with the company for decades, according to The Observer.
Combined Team Covers Design, Prototyping, and Full Production
ECI has long marketed itself as a "one-stop" electronics maker, guiding products from early design and prototyping all the way to high-volume manufacturing. Questek adds skills in CNC machining and over-molding — a process that seals wire connections in protective material — that complement ECI's existing capabilities, according to Whitecourt Star.
Together, the two companies now cover a wider range of technical challenges for customers. ECI's new product introduction team and Questek's precision assembly expertise create a stronger end-to-end pipeline, from the first sketch of a product to full-scale production runs, according to Seaforth Huron Expositor.
