Mississauga Approves One-Year Moratorium on AI Data Centers Amid Resident Concerns

Mississauga, Ontario, has placed a one-year moratorium on the development of artificial intelligence data centers, a move that diverges from a growing trend in the province. The city council unanimously approved the measure on Wednesday.

This decision marks a significant departure from the pattern seen in other Ontario municipalities. Hamilton's city council recently rejected a similar moratorium, while Vaughan has already approved a hyperscale AI data center, which is nearing completion. The approved moratorium in Mississauga raises questions about the future of such projects in the city, particularly a planned 50-100 megawatt facility near a residential neighborhood.

Concerns surrounding the significant power consumption, potential for heat islands, noise pollution, and water usage associated with hyperscale data centers were central to the council's decision. City councilor Alvin Tedjo highlighted the absence of current regulations, stating, "Right now there are no regulations. There’s no guardrails that would ensure what we’re looking for is what we get." Residents echoed these concerns, with some wearing anti-AI buttons to voice their opposition.

Dr. Mili Roy, a physician advocate from the University of Toronto, raised further environmental concerns. She noted that increased power demand could lead to greater reliance on gas-fired electricity, contributing to environmental issues. Additionally, research suggests data center water demands can exacerbate local water insecurity and drinking water contamination. One resident living near the proposed site emphasized that the potential benefits of the data center do not outweigh the health risks to residents.

Right now there are no regulations. There’s no guardrails that would ensure what we’re looking for is what we get. There’s a lot of concerns around power consumption, how that creates heat islands, the noise attenuation that’s going to be happening. We want to make sure there are safeguards so that the quality of life of residents isn’t affected by this in a negative way.
