Ontario AI Power Plan
Ontario implements higher electricity rates for large AI data centers, prioritizing local investment and data sovereignty.
Key Points
Ontario will establish a separate electricity rate class for large data centres (1 MW and above) that is higher than the existing industrial tariffs, while requiring developers to cover their own electricity costs and pursue on-site power generation.
Proposals must include plans to invest in electricity generation and transmission upgrades, and policy makers say there should be no impact on existing ratepayers as a result of data-centre development.
Decision-making over grid connections is centralized, with the province determining which large-load facilities can connect; the Minister of Energy and Mines has final authority.
Municipal moratoriums are being considered by several cities (e.g., Oakville’s one-year moratorium; Mississauga to vote on its own), but the playbook does not grant municipalities veto power over projects.
Ontario markets the framework as part of its AI strategy with projected economic benefits, including about $122 billion in economic growth by 2035 and roughly 17,000 jobs annually.
Ontario has unveiled a new framework for AI data centres that would force large facilities to pay higher electricity rates than other industrial users — and cover every dollar of their energy costs themselves. According to The Globe and Mail, any data centre above one megawatt will fall into a separate, higher-rate electricity class, with no burden passed on to existing ratepayers.
The province is marketing the move as a cornerstone of its AI strategy. Ontario projects the data centre sector could generate about $122 billion in economic growth by 2035 and support roughly 17,000 jobs annually, The Sudbury Star reported.
Higher Rates and No Subsidies for New Data Centres
Ontario's framework sets a clear rule: data centres pay their own way. Facilities over one megawatt will be placed in a new electricity rate class that charges more than existing industrial tariffs. The Globe and Mail reported that the province will offer no financial incentives to attract projects. Developers must instead show they can cover all electricity costs before connecting to the grid.
Proposals must also include plans to invest in electricity generation and transmission upgrades. The province says this ensures data centre growth does not raise bills for homes or businesses already on the grid. The Minister of Energy and Mines holds final authority over which large facilities can connect.
Province Keeps Control, Cities Kept on the Sidelines
Several Ontario cities are pushing back on the data centre boom. Oakville has already passed a one-year moratorium on new facilities. Mississauga is set to vote on its own. But the provincial playbook does not give municipalities veto power over projects, Northern News reported.
Decision-making stays with the province. The framework centralizes grid connection approvals so that local opposition cannot block a project outright. Cities can weigh in during a mandatory 30-day public consultation period, but the final call belongs to Queen's Park.
Build Your Own Power, Invest in Local Communities
Ontario wants data centres to generate their own electricity, not just buy it from the grid. The framework pushes developers to build on-site power sources and fund upgrades to local transmission lines. South Muskoka Doppler reported the policy also requires developers to invest in the communities where they set up shop.
The playbook rests on three pillars: economic development, data protection and digital sovereignty, and community investment. On sovereignty, the framework requires that data stay in Canada. The province frames this as a way to keep Canadians in control of their own information as AI use grows.
Sault Ste. Marie Moves to Write Its Own Rules
While Ontario sets the provincial baseline, some cities are not waiting. Sault Ste. Marie is drafting its own local framework to guide future data centre decisions, Cochrane Times Post reported. The city wants its own rules in place before any major proposals arrive.
The dual-track approach — province sets the floor, cities add local rules — shows how fast the data centre debate is moving across Ontario. The 30-day public consultation on the provincial playbook gives residents and councils a window to shape the final policy before it takes effect.
