eStruxture Data Centers is a Canadian colocation provider operating 16 data centers across four metro areas — Montreal, Toronto, Calgary, and Vancouver — with a fifth Calgary-area facility (CAL-3) under construction as of 2026. It bills itself as the largest Canadian-owned data center platform, with over 760,000 square feet of combined space and more than 130MW of power as of 2024, and it both builds and operates its own facilities rather than purely reselling third-party space. eStruxture’s clearest recent differentiator is its move into AI-scale infrastructure: in May 2026 it announced that CoreWeave, the Nasdaq-listed AI cloud provider, signed as anchor tenant for Phase 1 of CAL-3, a 90MW, Tier III-designed facility in Rocky View County outside Calgary built specifically for high-density AI/GPU workloads with rack densities up to 125kW. The company grew largely through acquisition — buying a Calgary facility from Shaw Communications in 2019 and, in a landmark 2021 deal, acquiring all eight Canadian data centers of Aptum Technologies (formerly Cogeco Peer 1), which added its Toronto and additional Montreal and Vancouver locations. In 2024, Fengate Asset Management led a CA$1.8 billion recapitalization of the company, described as the largest data center transaction in Canadian history.
