Data centre developer Stack Infrastructure has delivered the first phase of its Toronto campus.

The inaugural phase contains an eight-megawatt data centre and 48 MW of additional power capacity, the U.S. company said in a news release.

The 20-acre campus is located about 12 kilometres from 151 Front Street, the city’s largest carrier hotel and primary Internet exchange point, according to Stack. (Carrier hotels are buildings that accommodate data centres and cloud services in downtown cores.)

Denver-based Stack partnered with Toronto-based commercial real estate developer First Gulf, which renovated an existing building to deliver the initial data centre. A 24-MW expansion is slated to be delivered in the second quarter of 2026, with Toronto Hydro providing power from three diverse substations using 100%-renewable energy sources.

The third phase will offer another 24 MW on a campus designed as a purpose-built solution for scalability in a market with limited power capacity, said Stack.
