On September 22, 2026, ISED announced 19 additional signatories to Canada’s Responsible Data Centre Development Principles, bringing the total to 42. The principles were launched September 3. Signing expresses support for the framework; the count does not demonstrate that 42 projects have been built or independently audited.
Five expectations, different kinds of evidence
ISED summarizes the principles around local benefits, electricity affordability, water and environmental impacts, transparency and strategic Canadian value. The principles page provides the framework behind the signatory announcement. These are related government sources, not an independent impact assessment.
A useful community review translates each expectation into a question that can be answered for a proposed site. Who receives the benefits? Who bears infrastructure costs? Which resource estimates can be checked? What will be reported after operations begin? The signatory total cannot answer those questions for an individual project.

Ask for the full electricity and water picture
Our suggested evidence checklist starts with expected power demand, the timeline for connecting to the grid and responsibility for related upgrades. Separate the facility’s operating consumption from a proposal for future expansion. Ask which figures are estimates and which are based on measured operations.
For water, ask how use varies with cooling design, seasonal conditions and drought restrictions. An annual number can hide a period of high local demand. A clear explanation should identify the reporting boundary and describe how changes will be communicated. These questions are an analytical checklist, not claims about any signatory’s conduct.
Make local benefits specific enough to track
A construction job, a continuing operations role and a research partnership are different benefits. A proposal should distinguish them and date the assumptions. Communities can ask whether training, procurement and access arrangements have named partners and milestones.
For strategic value, ask who can actually use the capacity and on what terms. Canadian researchers and smaller firms may care about access, scheduling, pricing and technical support as much as the facility’s location. A statement about national value becomes more informative when it identifies the users and the work it will enable.
Follow the project after the signature
A practical public record would compare promised and actual resource use and benefits over time, explain changes and identify who is accountable for the reporting. An independent review should state what it inspected. Endorsement, a permit, an investment announcement and a commissioned facility are separate milestones.
This September update is significant as growing support for a national framework. Evidence of delivery must come from individual projects. Readers should keep both facts visible: the signatory list has grown, and the environmental and community outcomes still need to be demonstrated.

We use the linked original statements and reports to distinguish documented facts from our analysis. Company announcements describe their authors’ plans and claims; they are not independent verification of future outcomes. This article is dated and will be revised if material evidence changes.
