Ottawa's voluntary framework for data centre projects nearly doubled its backers in under three weeks — here is who joined, what they agreed to, and where the commitments stop.
Canada’s framework for responsible data centre development picked up 19 new corporate backers on September 22, 2026, when Innovation, Science and Economic Development Canada announced that the signatory list for Canada’s Responsible Data Centre Development Principles had grown to 42 organizations. The additions came from across the data centre, cloud, artificial intelligence and broader technology ecosystem, and included chipmakers, construction firms, energy companies and real estate investors.
The announcement, made from Ottawa, arrived less than three weeks after the principles were launched on September 3, 2026. Evan Solomon, Minister of Artificial Intelligence and Digital Innovation and Minister responsible for the Federal Economic Development Agency for Southern Ontario, presented the expansion as a signal that industry accepts a shared set of expectations at a moment when new data centre projects are drawing heavier public scrutiny over power, water and local impact.
Signatory Count Nearly Doubles From 23 to 42 in Under Three Weeks
The federal government’s own framing of the numbers is straightforward: the roster has “nearly doubled” from 23 organizations to 42. That growth rate matters more than the raw total, because it indicates that companies weighing large Canadian infrastructure decisions were willing to attach their names to a published set of conditions within weeks rather than months.
Ottawa did not announce any expansion of the principles themselves alongside the new signatures. The five expectations set out on September 3 remain unchanged; what changed on September 22 is the breadth of the industry sign-on, now spanning hardware manufacturers, IT services providers, energy developers and asset managers rather than operators alone.
The Five Expectations Every Signatory Is Endorsing
The principles function as a national reference point for how data centre projects should be planned and explained to the communities that host them. According to the government, projects are expected to meet five tests:
- Lasting local benefits: projects should leave measurable, durable value in the communities where they are built.
- Protection for electricity ratepayers: development should not shift costs onto households and other grid customers.
- Environmental responsibility: water use and broader environmental impacts should be minimized.
- Transparency: operators should be open about the local effects of a facility.
- Strategic value to Canada: the build should contribute to national capability, not merely occupy Canadian land and power.
The published material describes commitments rather than regulated obligations. No compliance mechanism, audit process, reporting cadence or penalty for non-adherence is specified in the announcement, and readers evaluating the framework should treat enforcement detail as not mentioned rather than assumed.
Chipmakers, Builders and Energy Firms on the New Signatory List
The 19 organizations added on September 22 cut across the full supply chain of an AI data centre — from silicon to substation to site construction.
| Category | New signatories |
|---|---|
| Semiconductors and computing hardware | AMD, Intel, NVIDIA, Lenovo, IBM |
| IT services and connectivity | Kyndryl, OnX, Global Relay |
| Data centre operators and platforms | STACK Infrastructure, Vantage Data Centers, Qu Data Centres |
| Energy, storage and thermal systems | Clearway Group of Companies, Energy Storage Canada, Enwave Energy Corporation, Potentia Renewables Inc., Red Jar Energy Partners, Schneider Electric |
| Construction and capital | EllisDon, Slate Asset Management |
The categories above group the names for readability; the government released them as a single alphabetical list without sector labels. The mix is notable for how much of it sits upstream and downstream of the server hall itself — an acknowledgement that power procurement, district energy, storage and construction practice determine whether a facility meets the ratepayer and environmental tests.
Solomon’s “If We Don’t Build It Here” Case for Domestic Compute
Solomon’s statement tied the framework directly to Canada’s compute sovereignty argument. He said the response to the principles had been “overwhelmingly positive” and that the industry was sending a clear message that Canada can build the digital infrastructure AI growth requires while protecting communities, supporting ratepayers and delivering lasting economic benefits.
The line the minister used to close the argument was blunt: if Canada does not build this capacity domestically, it will have to buy it from someone else. The principles, in his framing, are the mechanism that lets the country expand compute capacity “responsibly, transparently and in a way that earns Canadians’ trust” — a formulation that treats public confidence as a precondition for building, not an afterthought.
That emphasis on trust is consistent with the broader federal posture on artificial intelligence this year, which has paired investment announcements with governance messaging. Ottawa has been running a parallel track of digital transformation work announced by Prime Minister Carney, and the data centre principles slot into the same effort to make Canadian digital capacity a policy priority rather than a purely private build-out.
How the Principles Connect to AI for All and Sovereign Compute
The government states that the principles support its national AI strategy, AI for All, and its work to expand sovereign AI infrastructure and compute capacity within Canada. They also sit alongside the Canadian Sovereign AI Compute Strategy, which the announcement lists among its associated references.
The practical significance is that Ottawa is now attaching a behavioural expectation to the physical layer of that strategy. Compute capacity is not only a question of how many accelerators are installed; it is a question of where the electricity comes from, who absorbs the cost of new grid connections, how much water a cooling system draws, and what a municipality is told before a shovel goes in the ground.
For the investment community, the signatory list also functions as a soft market signal. Firms that manage capital and build facilities — Slate Asset Management and EllisDon among the new names — are indicating that alignment with the federal framework is compatible with their project economics, which is the kind of reassurance that tends to precede further announcements of the sort seen at the Canada Investment Summit’s capital commitments.
Why Ratepayers and Water Are the Pressure Points
General industry context, not drawn from the announcement: large-scale AI facilities are energy- and cooling-intensive by design, and in several jurisdictions the resulting debates have focused on who pays for new transmission and generation, and how much water evaporative cooling consumes in dry seasons. Provincial utilities and regulators, not the federal government, control most of the relevant approvals in Canada.
That division of powers helps explain why Ottawa chose a principles-based instrument. A voluntary national framework can set a common expectation across provinces without displacing provincial energy regulation — but it also means the specifics of ratepayer protection will still be settled case by case at utility hearings and municipal councils.
The transparency expectation is the one most likely to be tested first. Communities evaluating a proposal generally want load figures, water draw and construction timelines before approval, and signatories have now publicly accepted that disclosure is part of the deal. The announcement does not define what minimum disclosure looks like.
What Is Known About the Next Stage
The government did not announce a closing date for new signatures, a review point for the principles, or a schedule for reporting on how signatories are performing against the five expectations. Those details are not specified in the material released on September 22.
What is confirmed is the trajectory: a framework introduced on September 3 had 23 backers, and 19 days later it had 42. Whether that translates into changed project design — or remains a statement of intent — will be visible in the next round of Canadian data centre proposals and in how provincial regulators treat signatory status when applications reach them. Governance commitments of this kind are increasingly common across the AI sector, echoing the self-imposed guardrails seen in moves such as Anthropic’s tightened AI safeguards.
