J-AAR Supports Defeat Duchenne with Brown Bag Lunch Fundraiser

By Nick Wilton • July 28, 2025
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 Pours the Final Floor at Centro Tower Two

By Nick Wilton • July 22, 2025
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.

J-AAR Breaks Ground on Phase 3 of Yarmouth Yards at PowerCo Site

By Nick Wilton • July 22, 2025
We’re excited to share that J-AAR has officially broken ground on Phase 3 of the Yarmouth Yards project at the PowerCo site. This milestone marks the next chapter in a multi-phase build that has quickly become a standout collaboration between J-AAR and the City of St. Thomas. With phases one and two successfully delivered, Phase 3 is already shaping up to be another ambitious step forward. Last week, our team gathered alongside key stakeholders and project partners for a ground-breaking ceremony to celebrate the launch of this next stage. The event served as both a reflection on the progress we’ve made and a moment to look ahead at what’s still to come. So, what’s happening in Phase 3? This phase includes major site servicing, road construction, and additional civil infrastructure needed to support the City of St. Thomas' growing operations. Our crews are already mobilized, and activity on site is picking up quickly. As always, safety, efficiency, and craftsmanship remain our top priorities. The Yarmouth Yards project has already had a meaningful impact on the surrounding area. With each phase, we’re helping the City of St. Thomas push their long-term vision forward while creating jobs, strengthening infrastructure, and investing in future-ready spaces. We’re incredibly proud of the work done so far and even more excited about what’s ahead. Thanks to everyone who made this milestone possible. We’ll be sharing more updates as the build progresses, so be sure to follow along!
