Ontario Writes The Playbook: A New Framework For Data Centre Grid Connections

On August 13, Ontario released long-awaited details on how the province will regulate the connection of data centres to its electricity grid¹. Titled the Data Centre Playbook (the Playbook), the proposed framework outlines how the province plans to evaluate large-scale data centres against the government’s objectives of driving economic growth, keeping Canadians’ data in Canada, and delivering benefits to local communities². In addition to the Playbook, Ontario is also exploring a separate Global Adjustment (GA) rate class for new data centres. With consultation open until September 12, 2026, investors and other interested parties have the opportunity to provide feedback to shape the final regulatory regime.
