Oakville has implemented a one-year pause on new data centres, marking the first Ontario municipality to take this action amid concerns over the proliferation of facilities supporting artificial intelligence.
Local officials in Oakville have also instructed staff to review existing regulations to address potential issues such as noise, vibration, emissions, and broader land-use implications related to data centres. Mayor Rob Burton emphasized that the decision was made proactively and not in response to any specific application.
This move by Oakville comes as neighboring Mississauga prepares to vote on a similar pause, while other Ontario municipalities are exploring ways to regulate the development of data centres.
Although there are no formal data centre applications in Oakville, Hive Digital Technologies announced plans for a 320-megawatt AI facility in the Greater Toronto Area by the latter half of 2027. Records show that a Hive subsidiary acquired land in Oakville shortly before the announcement.
Councillor Tom Adams, representing the area where the property is situated, expressed support for Oakville’s moratorium, emphasizing the need for a comprehensive understanding of how data centres impact various infrastructures and residents’ well-being.
In response to the moratorium, a spokesperson for Hive stated that the company respects Oakville’s decision to establish a planning framework for data centre development and remains committed to transparency and community engagement.
The surge in demand for data centres, driven by competition among tech giants like OpenAI, Anthropic, Microsoft, and Google, has led to the proliferation of these energy-intensive facilities in Canada. While Canada currently has a limited number of large hyperscale data centres, numerous projects are in the pipeline, including Meta’s announcement of a one-gigawatt data centre in Alberta.
Various municipalities, including Hamilton, Mississauga, Waterloo Region, and Toronto, are exploring moratoriums or regulatory frameworks to manage the growth of data centres and their associated impacts on the environment and communities.
