Ontario's proposed Data Centre Playbook establishes a two-part assessment framework for grid connections, requiring data centres to fund full electricity costs while meeting strategic priorities around economic development, digital sovereignty, and community investment. The policy positions grid access as a key lever for governing data centre development amid surging demand that could reach 40% of the province's peak electricity capacity.

According to the Ontario Ministry of Energy and Mines, data centre connection applications currently in Ontario’s pipeline could exceed 10,000 MW, roughly 40% of the province’s recent peak electricity demand. Against that background, on August 13, 2026, the Government of Ontario released its Data Centre Playbook (the “Playbook”), a proposed policy framework intended to inform government decisions regarding whether regulated data centres may connect to the provincial electricity grid. It follows the Protect Ontario by Securing Affordable Energy for Generations Act (the “Act”), which received Royal Assent on December 11, 2025, and gives the Ontario government final decision-making power over grid connections by large-load facilities, including data centres. While the Act established the government’s approval authority, the Playbook may foreshadow forthcoming regulations under the Act.

Government Of Canada Makes Significant Changes To Energy Project Approvals Process

On September 3, the Government of Canada published amendments removing seven types of energy projects from the Physical Activities Regulations (the Project List) under the Impact Assessment Act (IAA). As a result, these types of projects will no longer be subject to the IAA but will continue to be regulated by the Canada Energy Regulator Act (CER Act) or applicable provincial environmental assessment regimes.
