Hamilton City Council Rejects Moratorium on New AI Data Centres

📅 1 day ago

Hamilton city councillors voted against a proposed temporary pause on new data centres, which could have set a precedent in Canada amidst rising concerns over their environmental impact.

HAMILTON, ONT. — On Wednesday, Hamilton city councillors voted 10-6 against a proposed temporary moratorium on new data centres, a decision that could have positioned the city as a pioneer in regulating these facilities amidst the burgeoning artificial intelligence sector. This proposed pause was intended to address rising concerns regarding the noise, energy consumption, and water usage associated with data centres that support AI technologies. However, several councillors who opposed the moratorium expressed concerns that it might deter new investments in Hamilton, a city grappling with a declining industrial sector. Mayor Andrea Horwath, who voted against the moratorium, emphasized the potential negative impact on local job opportunities, stating, "I think it will hold back Hamilton and reduce opportunity for many, many Hamiltonians and for generations to come."
The council's decision followed a lengthy closed-door session where legal advice was provided, suggesting that a data centre project spearheaded by McMaster University would have been exempt from the proposed pause. This legal insight influenced several councillors to reconsider their stance. Coun. Nrinder Nann, the sponsor of the moratorium, expressed disappointment that her proposal was misinterpreted as an opposition to investment. She clarified that the intention was to enable Hamilton to modernize its zoning and land use planning tools to accommodate AI data centres, which have not previously been considered in land-use discussions. Nann urged residents to continue engaging in the conversation about data centre regulations, asserting that "good projects do not need to be afraid of good rules."
Despite the council's decision, city staff will persist in studying the potential challenges posed by data centres, as directed by previous council resolutions. However, this outcome is unlikely to quell the concerns of the hundreds of residents who supported a temporary ban on data centres, regardless of their size or function. Proponents of the moratorium noted that the council's decision has sparked a broader discussion about the implications of AI data centres across Canada. Other municipalities, such as Mississauga and Vancouver, are also set to consider moratorium proposals in the near future.
Nick Tsergas, a resident and advocate for the moratorium, remarked that the issues surrounding electricity consumption, water usage, noise, land use, emergency planning, and public benefit will not dissipate simply because of the council's vote. He affirmed the commitment of moratorium supporters to remain actively involved in the ongoing dialogue.
The rejection of the moratorium clears a path for two prominent data centre proposals in Hamilton: one led by McMaster University and another by the Digital Research Alliance of Canada. Both projects are designed to incorporate public research components and are expected to be smaller in scale compared to the massive data centres operated by major AI corporations like Meta and OpenAI. Gianni Parise, McMaster's vice-president of research, expressed satisfaction with the council's decision, attributing the challenging position of councillors to misinformation and conflated issues surrounding data centres. The university is collaborating with s2e Technologies to develop a data centre on the site of the former Hamilton Spectator building, with no limit on the space allocated for researchers, although private sector involvement will be restricted to startups and small to medium enterprises.
The McMaster project is anticipated to unfold in two phases, with the first phase utilizing up to nine megawatts of power and the second phase requiring between 25 and 30 megawatts, which is comparable to the energy consumption of an automotive manufacturing facility but significantly less than that of larger AI data centres. Parise clarified that the focus of their data centre is not on generative consumer AI but rather on analytical science and predictive methodologies.
The other notable proposal comes from the Digital Research Alliance, a federally funded non-profit organization dedicated to securing computing resources for researchers. This alliance has chosen Hamilton for its application to Ottawa’s $890 million fund aimed at establishing a new supercomputing system. The proposed facility, which would be 60 percent public sector and the remainder divided between private sector and industry-academic partnerships, is the only one to have publicly indicated interest in a data centre at Steelport, a significant redevelopment site along Hamilton’s waterfront that was formerly home to steelmaking operations.
The proposed data centre at Steelport is expected to cover approximately 32,000 square metres, accounting for about one percent of the total industrial redevelopment area. Slate Asset Management, the developer behind Steelport, has applied for a connection to the Ontario power grid that would provide 200 megawatts of electricity, a request reflecting the capacity previously allocated for the old steel mill, with plans to seek additional capacity in the future. A spokesperson for Slate Asset Management acknowledged the concerns raised during the moratorium debate and stated that feedback from the community will continue to inform their future actions.
In a letter to the council, local utility Alectra mentioned that there is currently 519 megawatts of available capacity in their system nearby, attributed to a decrease in industrial demand. The competitive landscape among firms like OpenAI, Anthropic, Microsoft, and Google has led to a significant proliferation of data centres, which are essential for housing the powerful computer chips necessary for training and operating increasingly sophisticated AI models. These facilities typically require substantial amounts of electricity and water for cooling and powering their systems. A recent report from the United Nations University highlighted that the environmental impact of data centres worldwide is already comparable to that of some of the largest countries. While Canada has a limited number of large hyperscale data centres, many more are in development. Just last week, Meta announced plans for a new data centre in Alberta that will be powered by a gas plant and will consume electricity equivalent to three-quarters of the nearby city of Edmonton.
Data centre developers argue that the environmental impacts can be mitigated through sustainable design practices, including closed-loop cooling systems that recycle water and utilizing excess heat from servers for residential heating during winter months. Advocates for the moratorium in Hamilton voiced a desire for transparency and guarantees regarding the potential noise, water, and heat impacts of data centres, particularly in neighborhoods already burdened by industrial activity. Additionally, concerns were raised about the potential strain on the local electricity grid and the risk of increased utility costs, alongside apprehensions regarding the limited long-term employment opportunities offered by large data centres. The debate surrounding the moratorium also served as a platform for broader discussions about the rapid advancement of AI technology, encompassing issues such as workforce displacement and the spread of misinformation.
