Great Northern Insulation Relocates Woodstock Location to London, Ontario to Enhance Customer Service and Sustainability

London, ON – May 27, 2025 – Great Northern Insulation (GNI), a leading provider of insulation solutions in Canada, is proud to announce the relocation of its Woodstock branch to a new, state-of-the-art facility at 2485 Innovation Drive, London, Ontario. 

This move marks a significant milestone in GNI’s 40+ year history and reflects the company’s ongoing commitment to delivering exceptional service across Southwestern Ontario. The new London location will serve as the Southwestern Ontario hub for both office and production operations, with no changes to GNI’s service territory, including continued full service to Oxford County and surrounding communities. 

“We’re excited about what this new facility means for our customers and our team,” said Bill Maginas, CEO of Great Northern Insulation. “Being closer to more of our customer base allows us to respond faster, reduce travel times, and lower our environmental impact — all while continuing to deliver the high-quality service GNI is known for.” 

The new London facility is strategically located to improve operational efficiency and environmental performance. With a larger footprint and improved infrastructure, the facility is better equipped to support GNI’s growing operations. 

“This new location is not only physically larger, but it’s also better suited to our fleet and logistics,” said Rick Bartel, General Manager of Southwestern Ontario. “We’re able to dispatch more efficiently and reduce commute times to job sites, which means faster service for our customers and lower greenhouse gas emissions. It’s a win-win that aligns perfectly with our core value of Do The Right Thing.” 

While the Woodstock location at 935 Keyes Drive has been a foundational part of GNI’s legacy since 1980, the company remains deeply connected to the community and will continue to serve the region with the same expert level of service.
