Ontario releases rule framework for data centre development

Key Takeaways:

• The proposed playbook states that data centres must pay higher electricity rates and cover all power costs so standard ratepayers bear no financial burden.
• Facilities must also meet strict water and noise standards with preference given to closed-loop systems that use virtually no water.
• Approvals will depend on generating significant community benefits including investments in local infrastructure, training, and supply chains.

The Whole Story:

The Ontario government has launched a framework for a new “Data Centre Playbook” aimed at attracting technology investments while requiring operators to cover the full cost of their electricity consumption.

The proposed framework establishes rules for how large-scale data facilities will connect to the province’s power grid. Under the proposal, facilities exceeding one megawatt in size will be subject to a separate, higher electricity rate than standard industrial users, and projects that generate their own power will be prioritized.

Premier Doug Ford said the strategy is designed to build the province’s artificial intelligence infrastructure while ensuring costs are not passed on to residential energy users.

“Ontario has a choice: we can build the economy of the future and ensure Canadians’ data remains in Canada, or we can get left behind and risk Canadians’ data being sent to the U.S. and elsewhere,” Ford said in a release. “Any data centre investment will need to invest significantly in local communities and pay more for electricity so no energy costs are passed on to hardworking families.”

The initiative falls under recent authority granted through the Protect Ontario by Securing Affordable Energy for Generations Act, which gives the Minister of Energy and Mines final approval over grid connections for large-load facilities.

Energy and Mines Minister Stephen Lecce emphasized that the province will only offer non-financial incentives to prospective developers.

“We have designed a system that protects families and ensures data centres pay for complete cost of power — every single cent,” Lecce said. “To make this point, Ontario will be introducing a new higher electricity rate for data centres, in addition to prioritization for projects that generate their own power.”

The framework rests on three main criteria for project approval: economic development and supply chain support, digital sovereignty to keep Canadian data within national borders, and direct community investment. Environmental requirements will also require projects to meet standards regarding noise and water usage, with preference given to closed-loop cooling systems.

Economic Development Minister Vic Fedeli said the playbook will serve as an evaluation tool as demand for digital infrastructure grows, helping lay the groundwork for a broader provincial AI strategy. According to government estimates, expanding the AI sector could generate $122 billion in economic growth by 2035.

“As demand for digital infrastructure continues to grow at an unprecedented pace, our government is taking bold action to ensure Ontario’s interests remain protected and prioritized,” Fedeli said.

The province has opened a 30-day public consultation period on the framework through the Environmental Registry of Ontario and the Ontario Regulatory Registry, running through mid-September.

Growth in Ontario’s data centre pipeline is already accelerating, driven by major industrial and tech sector investments across the province. Major tech firms, including Microsoft, have committed billions toward regional cloud and artificial intelligence infrastructure, with new high-density facilities slated to come online through 2026. Developers are also aggressively assembling large parcels of land in key industrial corridors like Milton and northern GTA municipalities, while federal initiatives actively solicit proposals for sovereign AI data centres exceeding 100 megawatts.
