CoreWeave signs as anchor tenant for eStruxture’s new Calgary AI data center

Calgary has spent years watching Toronto and Vancouver absorb most of Canada’s tech investment conversation. Recently, however, that dynamic is shifting, and a new data center deal offers a concrete signal of where things are heading.

eStruxture Data Centers this week confirmed that CoreWeave, the US-based AI cloud provider, has signed as the anchor tenant for Phase I of CAL-3, eStruxture’s new 90MW facility in Rocky View County, just outside Calgary. Scheduled to come online in the second half of 2026, the site will offer rack densities up to 125kW, which positions it firmly at the high-performance end of the market.

CoreWeave’s decision to anchor the facility carries weight beyond the contract itself. For context, the company currently serves customers including OpenAI, Microsoft, IBM, Nvidia, and Meta. It recently crossed 1GW of active data center capacity across nearly 50 facilities and is working toward 1.7GW by the end of 2026. Furthermore, the company has 3.5GW contracted for delivery by 2027 and as much as 8GW targeted by 2030. When an operator at that scale commits to a regional facility, it tends to signal something meaningful about where demand is actually moving.

Sachin Jain, chief operating officer at CoreWeave, pointed to Alberta‘s policy environment as part of the decision. Specifically, he noted that provincial support and Invest Alberta’s involvement shaped the company’s confidence in making a long-term infrastructure commitment there. For smaller regions competing for AI investment, that kind of institutional backing increasingly matters alongside the technical specs of the building itself.

For eStruxture, meanwhile, the deal marks another step in a growth trajectory that has accelerated since Fengate Asset Management acquired the company in 2024 for 1.8 billion Canadian dollars. Today, eStruxture operates 16 facilities across Canada, with CAL-3 representing its most ambitious Calgary project to date.

The broader pattern here is also worth noting. CoreWeave largely relies on third-party data center operators rather than building its own facilities. As a result, its tenant commitments function as a direct endorsement of both the operator and the market. In that context, anchoring CAL-3 puts Calgary alongside Ontario in CoreWeave’s Canadian footprint and confirms that western Canada is becoming a serious destination for AI infrastructure spending.

For the region, the ripple effects of large-scale AI infrastructure tend to compound meaningfully over time.
