EllisDon: The Builder Behind Your Digital World

EllisDon is shaping the backbone of Canada’s digital economy, where advanced construction meets critical infrastructure.

Have you ever wondered where your digital life really lives?

Beyond the photos you save to the cloud or the passwords your phone remembers lies an entire digital ecosystem – the applications that power business and communication, the AI that drives automation and insight, and the data itself: banking details, health records, work files, private messages, and the most sensitive government and financial information.

All of it exists somewhere – stored securely, processed continuously, and made accessible only to those who are meant to see it.

The answer lies in one of the most essential yet least visible parts of our digital world: data centers. As Canada’s number one builder of data centers, EllisDon is at the forefront of constructing the facilities that keep our digital world running. With deep technical expertise, a national footprint, and a proven track record, we deliver data centers that meet the highest standards of performance, security, and scalability.

Whether for hyperscale providers, developers, enterprise clients, or government partners, EllisDon is trusted to build the physical foundation for the cloud, the applications that drive innovation, and the AI that is redefining what’s possible – the true backbone of Canada’s digital economy and beyond.

In-House Expertise

With over 140 professionals dedicated exclusively to this sector, EllisDon has developed the largest and most specialized data center team in Canada. These experts lead projects across the full lifecycle – from early design through commissioning and operations – responding to the demands of digital infrastructure with precision, speed, and foresight.

Through close coordination across disciplines, our team brings clarity and confidence to early budgets and schedules, enhances constructability, and ensures technical precision from the outset. With a fully integrated delivery model, EllisDon anticipates challenges before they arise, streamlines execution, and consistently delivers facilities that perform at the highest level.

Coast to Coast Leadership

EllisDon has been Canada’s data center builder of choice since the days when enterprises built their own facilities, and 10 MW of critical load was considered substantial. Over that time, we have delivered many of Canada’s largest and most complex data centers across the country, including:

• The first Canadian greenfield data center for a top three global provider of search, cloud, and AI services — Montreal, Quebec
• Ericsson’s first data center outside Sweden — Vaudreuil-Dorion, Quebec
• TD’s flagship data center — Barrie, Ontario
• Canada’s first wholesale data center for Digital Realty — Toronto, Ontario
• The first two Canadian greenfield data centers for the world’s largest provider of software, cloud computing, and AI solutions — Toronto, Ontario
• STACK’s Canadian data centers — Toronto and Calgary
• Key upgrades and expansions for Equinix — Kamloops, BC; Calgary, Alberta; and Toronto, Ontario

Together, these premier projects tell a story of trust, precision, and vision — a story we continue to build with every data center project that follows.

“EllisDon supports developments of any scale, in any province, while consistently achieving the lowest cost per megawatt in Canada. As the industry evolves—driven by AI and increasing demand for digital infrastructure—we are engaging earlier in the process, often at the developer level, to shape purpose-built facilities from the ground up. We’re not just building faster; we’re building smarter.”
