Telehouse is deploying liquid cooling in its Canadian data centers in Toronto.

KDDI’s Telehouse Canada this week announced it has introduced direct liquid‑to‑chip technology at its downtown Toronto data center environments.

Full details haven’t been shared, but the deployment supports organizations wanting to deploy AI infrastructure, offering densities of up to 120kW per rack. The company said the deployment is the first of its kind in Canadian carrier hotels.

“As demand for AI continues to grow, organizations need data center infrastructure that can support increasingly complex workloads at scale,” said Atsushi Kubo, president and CEO of Telehouse Canada. “This upgrade strengthens our ability to meet those needs while continuing to deliver the performance and reliability our customers expect.”

The excess heat from liquid-cooled equipment is set to be transferred to Enwave’s closed-loop district energy system, where it is captured and repurposed through a fully isolated process to help heat Toronto’s municipal drinking water.

Established in 1988 and owned by Japanese telco KDDI, Telehouse operates in 15 cities globally, including the US, UK, Canada, France, Germany, China, Singapore, Vietnam, and Japan.

Telehouse launched in Canada in 2024 after acquiring three data centers in Toronto from Allied Properties REIT.

151 Front St. West totals 205,000 sq ft (19,045 sqm) of IT space and 20MW, 250 Front St. West totals 82,000 sq ft (7,620 sqm) and 10MW, and 905 King St. totals 69,000 sq ft (6,410 sqm) and 10MW. Customers across the three sites include Digital Realty, Equinix, and Cologix.

The 151 and 250 Front St. data centers are cooled primarily through a Deep Lake Water Cooling System (DLWC) from Enwave. The system harnesses the cold temperature at the bottom of Lake Ontario to cool nearby 190 buildings, including hospitals, data centers, educational campuses, and more.
