55H has announced a phased expansion of its data center capacity in Brampton, Ontario.

At the 55 Hereford Street site, the expansion will deliver 20MW of IT capacity in three stages to meet the growing demands of AI clients.

Phase I is immediately available, providing 2.5MW for lease. Phase II and Phase III will deliver a further 2.5MW and 15MW in summer 2025 and 2026, respectively.

The expansion is in partnership with Core Data Centers.

The facility spans 215,000 sq ft and is located just outside Toronto. 55H said it can support up to 130kW per rack with liquid cooling solutions.

55H was formed in a joint venture between investment firms Grain Management and StratCap in June 2023, when the companies acquired the property at 55 Hereford Street.

The site was formerly an enterprise facility operated by Canadian food retailer Loblaw Companies Limited. It is adjacent to a Loblaw office building, and the company has an Uptime Certificate for a Tier III facility in Brampton.

“Our commitment to supporting the AI industry is demonstrated through this significant investment in our infrastructure,” said Bryan Marsh, CEO of 55H. “By providing scalable and robust power solutions, we enable our clients to focus on innovation without the concern of capacity constraints.”

Core Data Centers has one other data center in Markham, also in Ontario.

Toronto, in the province of Ontario, is home to the likes of Digital Realty, Hut 8, Cologix, Telehouse, Centersquare, EdgeConneX, Coloware, Cogent, Ascent, Stack, Microsoft, Compass, Exa Infrastructure, and Equinix.
