Mississauga Considers Data Centre Moratorium Amid Environmental and Community Concerns

City councillors in Mississauga have voted in favour of a proposed one-year moratorium on new data centre developments. This decision stems from growing concerns among councillors regarding the potential environmental and community impacts of these large-scale facilities. The moratorium will provide a dedicated period for the city to study the effects of data centres, establish appropriate regulatory frameworks, and engage in public and industry consultations.

Councillor Martin Reid put forward the motion, highlighting that the specifics of a major proposed data centre's usage and the company operating it remain undisclosed. This lack of transparency makes it difficult to assess potential impacts on water and energy consumption, noise levels, and local wildlife. Councillor Sue McFadden echoed these concerns, emphasizing the unknown environmental effects and the sheer scale of a proposed facility, described as being as large as three football fields.

While the building company, Prologis, has stated it provided technical information and followed notification procedures, including a public town hall, uncertainties persist for local officials and residents. Concerns were raised about public notification, as some residents living outside the 600-meter radius typically used for mandatory notice were unaware of the proposed development.

Mississauga's move reflects a broader trend in Ontario, where municipalities are grappling with the rapid growth of data centres. Toronto city council recently requested the provincial government to create a province-wide framework for data centres, though some advocates argue for local moratoriums. In contrast, Hamilton city councillors recently rejected a similar pause, citing potential risks to investment and research-oriented projects.

The debate has also entered the political arena within Mississauga, influencing local elections. Council is set to finalize the bylaw for the moratorium in September, with ongoing efforts to ensure community concerns are addressed and appropriate safeguards are implemented before further development proceeds.
