KITCHENER, ON | OCTOBER 6, 2025 — J-AAR Limited, a family-owned construction company with locations in London and Cambridge, Ontario, has acquired the heavy civil road construction operations of The Seegmiller Group of Companies. This transition allows Seegmiller’s construction employees to continue their work under J-AAR’s leadership, contribute to ongoing regional projects, and benefit from the shared strengths, experience, and future collaboration opportunities between the two organizations. “We are excited to welcome the Seegmiller’s road building operations into J-AAR and continue delivering important infrastructure projects to the communities we serve,” said Ryan Aarts, CEO of J-AAR. “Like Seegmiller, we are a family-owned business with a commitment to our people and local communities. We look forward to building on their legacy and collaborating together in ways that strengthen our industry and communities.” J-AAR is actively managing several infrastructure projects in Waterloo Region, including the new Dundee Roundabout, the Frederick Street reconstruction, and the new Cowan Recreation Centre on Huron Road. “We have seen a lot of change in the industry in the last decade, and this transition positions the Seegmiller Group to align its businesses with opportunities that we see ahead,” said Nora Seegmiller, President of the Seegmiller Group of Companies. “My dad, Tim, has always believed that our people are our most valuable assets. We are proud to share our team with a company as vibrant as J-AAR and feel this step helps ensure a strong, successful future for the teams and communities we serve.” Founded nearly a century ago, The Seegmiller Group is a fourth-generation, family-owned and led business that has been serving Ontario’s construction and aggregate industries since 1927. While E&E Seegmiller is known as one of the region’s most experienced full-service private construction companies, The Seegmiller Group will focus on new opportunities outside the civil road reconstruction industry, including aggregate supply, land development and specialized equipment repair. “My family and I will continue to support J-AAR and are fully invested in the success of the civil construction operations now under their leadership,” said Seegmiller. “We look forward to seeing the team thrive and continuing the legacy of excellence they’ve built in the communities we all serve.” The transaction is effective October 3, 2025, marking a new chapter for J-AAR as it takes on Seegmiller’s civil construction operations, and for Seegmiller as it focuses on new opportunities. Both companies remain guided by family-led leadership and a shared commitment to people, projects, and communities.

J-AAR is proud to continue its partnership with LiUNA Local 1059 through their Charity Partnership Program, making a meaningful difference in the community with a $5,000 donation to the Children’s Health Foundation. This initiative is part of a three-year commitment where LiUNA donates $5,000 annually on behalf of J-AAR to a local charity of our choice. Last year, the funds supported Youth Opportunities Unlimited (YOU), helping empower youth in our region with critical resources and programs. This year, we are honoured to direct the support to the Children’s Health Foundation, where the funds will help provide life-saving equipment, state-of-the-art care, and vital support programs for children and families across Southwestern Ontario. The cheque presentation took place on September 30, with representatives from LiUNA 1059, J-AAR, and the Children’s Health Foundation in attendance. It was an opportunity to celebrate the power of collaboration between industry and community, and to highlight the shared commitment to giving back. At J-AAR, our work extends beyond construction. We believe in building stronger communities by supporting the organizations that provide essential care and opportunities for the people of Southwestern Ontario.

The J-AAR team, together with project partners and community leaders, officially broke ground on Phase 1 of the Timber Ridge subdivision on September 18.

A Milestone for the Community The morning ceremony gathered representatives from Timber Ridge Developments, local officials, home builders and J-AAR employees who will bring the vision to life. Guests viewed the first preparations for underground servicing and road construction, which will pave the way for new homes and community amenities. About Phase 1 Phase 1 includes essential site servicing and infrastructure for the initial group of residential lots, with work now underway on grading, utilities, and roadwork. This first phase sets the foundation for a multi-phase project designed to grow alongside the needs of Lucan’s expanding population. Partnership and Vision J-AAR is proud to work alongside owners Mike Radcliffe and Barry Gilmour of Gilrad Developments, whose vision for a high-quality, welcoming subdivision has guided every step of planning. The partnership underscores a shared commitment to craftsmanship, sustainability, and community growth.

Future phases will follow as the new neighborhood rises, creating a vibrant, family-oriented community in the heart of Middlesex County.

J-AAR is proud to support Defeat Duchenne, Canada’s leading charity dedicated solely to funding research into Duchenne muscular dystrophy (DMD). This year, our efforts included a company-wide Brown Bag Lunch Fundraiser, and thanks to the incredible generosity and teamwork of our staff, we raised an impressive $2,750 for the cause. Spearheaded by our Business Intelligence team, the event was a true example of collaboration across divisions. Volunteers stayed after work to thoughtfully prepare each brown bag lunch, while others visited various J-AAR sites to distribute and sell them throughout the day. We want to give a huge thank you to: - Our BI team for organizing and leading the initiative - All the volunteers who stayed late to assemble the lunches - Everyone who took time to travel to our sites and sell them - And of course, the entire J-AAR team for purchasing, donating, and supporting this meaningful cause Your efforts made a real difference and helped advance the mission of Defeat Duchenne, funding the research that will lead to better treatments and, one day, a cure for Duchenne.

J-AAR is proud to announce the successful pour of the 30th and final floor of Centro Tower Two, marking a major construction milestone for this landmark downtown development. After years of coordinated effort, tight timelines, and precision execution, the final concrete pour took place earlier this month, bringing the second tower at Centro to its full height. This achievement represents not only the structural completion of Tower Two, but also a significant step forward in reshaping London’s skyline. J-AAR’s Structural Division has been leading the vertical construction on this tower from day one, working closely with Old Oak and the broader project team to deliver on schedule while maintaining the high standards of quality and safety that define every J-AAR build. Centro Tower Two is the second phase of the highly anticipated Centro development, offering a mix of modern residential units and amenity spaces in the heart of London. The tower’s contemporary design, expansive city views, and walkable location make it a standout addition to the downtown core. What's Next? With the structure now topped out, the focus shifts to envelope, interior finishes, and systems installation. Our team will remain on-site to support the next phase of construction and ensure a seamless transition from structure to occupancy. We’d like to thank everyone involved in helping us reach this milestone, from our field crews and engineers to our partners and suppliers. We’re proud to play a role in building the future of downtown London, one floor at a time.
