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.
