Ontario Bill 40 Introduces Grid Connection Screening That Could Reshape Toronto Data Center Development
Ontario's proposed Bill 40 legislation will fundamentally alter how large data centers access grid connections by requiring ministerial approval for projects above certain MW thresholds, creating new barriers based on size, location, and economic value assessments. The legislation establishes a three-tier screening process evaluating MW capacity, geographic placement in constrained versus surplus grid areas, and strategic economic contribution to the province. As a result, Toronto's balanced 7% vacancy rate may tighten as developers accelerate preapproval activities for planned projects. Operators are adapting to the regulatory shift by prioritizing sites in grid surplus areas and strengthening economic impact proposals, particularly for AI and cloud infrastructure that demonstrates higher strategic value. While Toronto has historically attracted development through proximity to financial districts and enterprise customers, future growth will increasingly depend on navigating ministerial approval processes and demonstrating alignment with provincial energy priorities.
The screening framework signals Ontario's intent to manage data center growth strategically rather than reactively. For the broader Canadian market, Bill 40 establishes a regulatory model that other provinces may adopt as data center demand intensifies, making early regulatory compliance and site selection increasingly critical for competitive positioning.
