EllisDon

EllisDon builds things at scale - buildings, healthcare facilities, mixed-use and cultural projects, education, government and judicial work, civil infrastructure, industrial sites - and increasingly it builds them as data. The company runs Virtual Design and Construction (3D modelling, reality capture, drone imaging, digital asset solutions) alongside a Data & Digital Engineering team it describes as unique in the industry, tasked with making complex project delivery more efficient across any scale or phase. That means the sensitive surface isn't just corporate email: it's federated models, drone-captured site imagery, reality-capture point clouds, and digital asset records that flow between offices, jobsites, subcontractors, and clients from sketch to skyline.

The threat model follows the workload. EllisDon delivers on a full-service, Cradle-to-Grave basis - pre-construction, construction, post-construction, and capital financing for non-profit and government groups - so data crosses organizational boundaries and long project timelines, in a vertical mix that includes healthcare, government and judicial, and education. Headquarters sits in Mississauga, Ontario, with work across Canada and internationally. Field tooling (drones, reality capture, mobile capture on active sites) and digital asset solutions widen the perimeter in ways a standard office network never does.

EllisDon's own framing is a diverse team of cross-phase professionals operating as a single partner across the lifecycle, with an explicit emphasis on digital innovation and efficiency. Security work in that environment is inherently cross-domain: IT and field operations, design data and financial arrangements, corporate infrastructure and project-specific collaboration. The company has not published specifics on its security organization, tooling, or team size - candidates should ask directly.
