Ontario Cities Seek Regulations for AI Data Centres

Municipalities across Ontario are pushing for a province-wide regulatory framework for AI data centres to address concerns regarding noise pollution, water depletion, and energy consumption. In Mississauga, city council voted unanimously for a one-year moratorium to conduct an impact review, while Toronto city council requested that the province establish rules by the first quarter of 2027. Green Party Leader Mike Schreiner has called for a broader moratorium on all new construction until protections for communities and the environment are in place.

In Sault Ste. Marie, city council is considering an interim control bylaw to prohibit data centre development. This move directly impacts a proposed project by the Missanabie Cree First Nation, which plans to build a 5 MW secure computing facility and workforce training centre on Yates Avenue. Chief Jason Gauthier has defended the project as a small, community-scale facility distinct from massive hyperscale centres, emphasizing its role in protecting domestic sensitive information and creating 200 jobs.

The government of Ontario has already implemented legislation requiring data centres to obtain government approval before connecting to the energy grid to prevent electricity costs from rising for residents. Energy Minister Stephen Lecce stated that no project will proceed unless it contributes to the local economy and the company pays the full cost of energy.
