Canada's Data Centre Boom: Lessons from New York

The Dark Side of Cloud Computing: Can Canada Learn from New York’s Cautionary Tale?
As Canada grapples with its own “hot data centre summer,” with multiple major projects underway and more planned, concerns about the rapid growth of cloud computing and artificial intelligence (AI) have come into sharp focus. New York’s decision to pause development on new hyperscale data centres is a stark reminder that the environmental impact of these massive facilities cannot be ignored.
The issue at hand extends beyond environmental concerns, however. Hyperscale data centres also strain local power grids and water supplies, and their development often lacks transparency and public consultation. In Hamilton, Ontario, city council recently voted down a proposed moratorium on new data centres, but the importance of addressing these issues will only continue to grow.
Hyperscale data centres’ voracious appetite for energy is a major concern. According to estimates, they accounted for around 1.5% of global energy consumption in 2024 – a number expected to more than double by 2030. Moreover, the type of energy being consumed is often cheap but locally costly, putting a strain on local communities and their resources.
Data centres also have significant water usage concerns. While they may use less water overall compared to other industries, localized demand can put a strain on already stretched resources. Research has shown that irrigation in the United States alone used nearly 100 trillion litres of water in 2023 – more than 20 times the amount used by global data centres for AI workloads.
Canada’s approach to regulating hyperscale data centres is at a critical juncture. With several major projects underway and many more planned, it is essential to take a closer look at our own regulatory framework. While some provinces have expressed caution, others seem eager to welcome in the data centre boom without proper consideration for its potential impacts.
The question now is whether Canada can learn from New York’s cautionary tale and take steps to mitigate the risks associated with hyperscale data centres. Can we find a balance between supporting innovation and protecting our communities? Or will we continue down the path of rapid growth, ignoring warning signs until it’s too late?
Canada needs to start thinking about the long-term consequences of its data centre boom – not just the short-term benefits it promises. This means engaging with local communities, conducting thorough environmental assessments, and implementing stricter regulations on energy and water usage.
If Canada fails to act, we risk repeating the mistakes of the past and facing a future where the costs of cloud computing far outweigh any potential benefits. The clock is ticking – will Canada take the lead on responsible data centre development, or will it follow in New York’s footsteps?

The focus on environmental impact is welcome, but let's not overlook the economic elephant in the room: Canada's reliance on these massive facilities may also be undermining our competitiveness in other industries that don't carry such a significant carbon footprint. We need to consider whether this boom is creating long-term dependencies rather than driving innovation and diversification. With so many projects underway, it's time for policymakers to think strategically about balancing the data centre sector with more sustainable and resilient economic models.

While the environmental concerns surrounding hyperscale data centres are well-documented, another critical aspect of these massive facilities is often overlooked: their impact on local economic development. In a region where a single large project can provide hundreds of jobs and millions in investment, do we risk over-reliance on a transient industry that may ultimately leave our communities with little more than a legacy of stranded infrastructure?

While the article highlights the environmental and social implications of Canada's data centre boom, one often-overlooked aspect is the human cost of these massive projects. Local communities are frequently pitted against tech giants in bitter battles over land use and development rights. In New York, for instance, community resistance helped spark the state's decision to pause hyperscale data centre development. As Canada continues down this path, it must prioritize inclusive, participatory planning processes that ensure local voices are heard alongside corporate interests.
