Canada\u2019s digital future is often described through the language of speed, productivity, and innovation. Artificial intelligence is expected to transform industries, accelerate research, improve public services, and strengthen economic competitiveness.<\/span><\/p>\n

Yet behind every AI system is a physical footprint that is much easier to overlook.<\/span><\/p>\n

The digital economy depends on data centres: buildings filled with servers that store, process, and move information. They support cloud computing, online banking, healthcare systems, cybersecurity, streaming, and increasingly, the AI tools that are becoming part of daily life. Inside these facilities, thousands of servers run continuously, generate heat, and require constant cooling.<\/span><\/p>\n

Can Our Systems Support AI Growth?<\/b><\/strong><\/h2>\n

The International Energy Agency estimates that global electricity consumption from data centres could <\/span>more than double<\/b> by 2030. Data centre electricity demand is also expected to rise by about 15% per year between 2024 and 2030, more than four times faster than electricity demand from all other sectors combined.<\/span><\/p>\n

The pressure on electricity also appears on water. In Canada, data centre water consumption is estimated at 69.54 billion litres in 2026 and projected to reach 99.34 billion litres by 2031.<\/span><\/p>\n

Large data centres can consume millions of litres of water per day, with 80 to 90% of that water being potable, or drinking-quality, water. A mid-sized data centre has been estimated to use about 1.13 million litres of water per day, roughly the daily water use of 5,000 Canadians. The real footprint is even larger, as this estimate does not include the water used indirectly through electricity generation.<\/span><\/p>\n

The Myth of Unlimited Water<\/b><\/strong><\/h2>\n

The expansion of AI is taking place simultaneously as water systems are already facing pressure from drought, aging infrastructure, population growth, leakage, and rising industrial demand.<\/span><\/p>\n

As of September 2025, 85% of Canada\u2019s agricultural landscape was classified as abnormally dry or in drought, including 67% in moderate to extreme drought. Drought is usually discussed through agriculture, wildfires, or drinking water restrictions, but it also affects the conditions under which new industries can grow. The country is therefore facing growing uncertainty around access to stable and well-distributed water.<\/span><\/p>\n

Canada\u2019s myth of water abundance sheds light on a key message: digital infrastructure cannot be treated separately from its water infrastructure.<\/span><\/p>\n

An Invisible Cooling Problem<\/b><\/strong><\/h2>\n

As data centres use more computing power, their servers generate increasing amounts of heat. Without effective cooling, equipment can overheat and digital services can fail, making temperature control key to data centre operations.<\/span><\/p>\n

However, cooling involves multiple trade-offs. Some systems use more electricity, while some use more water. Others reduce energy demand by relying on evaporative cooling. In fact, 80 to 90% of water used is lost to evaporation during cooling without being returned to watersheds. When put into perspective, a cooling system that appears energy-efficient can still create another kind of pressure by increasing demand on local water supplies.<\/span><\/p>\n

Data centres are often evaluated through energy use, emissions, and power availability. Water is reported less consistently, leaving an incomplete picture of the pressures these facilities can place on local resources.<\/span><\/p>\n

When data centres draw from municipal systems, the issue affects not only a company\u2019s operations, it also impacts:<\/span><\/p>\n
