Oakville has implemented a one-year pause on new data centre constructions, marking the first instance in Ontario where a municipality has taken such action in response to concerns surrounding the proliferation of facilities supporting artificial intelligence.
Local officials have also tasked staff with examining whether existing town regulations need revisions to address potential issues like noise, vibration, emissions from data centres, and broader land-use implications.
Mayor Rob Burton emphasized that the decision was made proactively and not in response to any specific application, highlighting the council’s responsibility to stay vigilant and take necessary actions.
The move by Oakville comes as neighboring Mississauga prepares for a vote next month on a similar temporary halt, while other Ontario municipalities are exploring ways to regulate these new developments.
Although Oakville has not received any formal data centre proposals, developer Hive Digital Technologies announced plans in May for a 320-megawatt AI facility in the Greater Toronto Area scheduled for late 2027, with records showing a Hive subsidiary acquiring property in Oakville shortly before the announcement.
Coun. Tom Adams, representing the area where the property is located, expressed support for Oakville’s moratorium, emphasizing the need for a thorough understanding of how data centres impact various aspects of the town’s infrastructure and residents’ well-being.
In response to the moratorium, a spokesperson for Hive stated the company’s respect for Oakville’s decision to establish a planning framework for data centre development and reiterated their commitment to transparency with the community.
The surge in demand for data centres, driven by competition among tech giants like OpenAI, Anthropic, Microsoft, and Google, has prompted a heightened interest in regulating these energy-intensive facilities. While Canada currently has a limited number of large hyperscale data centres, numerous others are in the pipeline, including Meta’s proposed one-gigawatt data centre in Alberta.
Various municipalities, including Hamilton and Waterloo Region, are exploring measures to assess and manage data centre developments, with Toronto city council recently passing a motion in this regard.
As the discussion on data centre regulation unfolds across Ontario, it is evident that local governments are actively considering the implications of these facilities on their communities and infrastructure.
