AI DATA CENTRES

Burlington Defeats AI Moratorium: What You Need to Know

Burlington City Council has officially defeated the proposed moratorium on new AI data centres. 

Here is a breakdown of the developer’s proposal, why residents fought back, and why the City ultimately backed down.

The Developer’s Proposal: The proposed data centre facility at 3110 South Service Road is a 17-megawatt, medium-sized enterprise and colocation centre. Taking up roughly 16,400 sq ft., the developers claim it will rely entirely on an air-cooling system.

Residents argued that:

1. Outdated Zoning and Zero Jobs: The challenge for the local residents is that Burlington’s zoning definitions are outdated and rely heavily on employment density, with no clear rules for data centres. Residents correctly pointed out that this facility behaves nothing like a traditional business. Once built, it will operate with a skeleton crew, meaning we are giving up valuable commercial space to a massive, fenced-off server warehouse with zero economic benefit to the City.

2. Constant 24/7 Noise Pollution: Noise was the key trigger for community opposition. The proposed air-cooled system still requires heavy-duty rooftop condensers, large chiller pumps, and massive exhaust shafts to keep the building cool. Residents argued that unlike regular highway traffic that peaks during the day, this mechanical hum never stops, leaving residents facing a constant, 24/7 disruption.

3. Strain on Utility Infrastructure: Many residents expressed concern over the massive energy drain that the 17 MW facility would have on the grid system. Residents argued that this immense power draw could limit Burlington’s electricity capacity for future residential housing and economic development. Furthermore, the strain on Burlington Hydro’s infrastructure could push up utility rates for local taxpayers.

4. Deep Environmental Skepticism: Almost all the residents who presented at Council remained highly skeptical of the developer’s claim that the facility would not drain the local water system. Many expressed the fear that as summers get increasingly hotter, the air-cooling system will fail to keep up, forcing the facility to pivot to a much more water-intensive cooling method.

Why the Moratorium Failed: 

1. Council was largely driven by a fear of legal risks and the optics of losing tech investment. Councillors were warned that an interim control bylaw (a freeze) lacked specific zoning tools. Trying to freeze a facility that technically complies with our broad, existing employment zoning would likely result in a drawn-out, losing battle at the Ontario Land Tribunal.

2. The Hamilton Precedent: Hamilton’s recent 10-6 vote against a similar moratorium set a strong regional precedent that heavily influenced Burlington’s decision to back down.

3. Exemption Loopholes: Council also feared legal loopholes. Projects that are already at an advanced stage of development, or those involving partnerships with universities, have a legal right to bypass an interim bylaw and proceed directly to a site plan application anyway.

The Final Decision and Next Steps: Ultimately, Council defeated the complicated motion for the moratorium. Instead, they directed City staff to:

1. Update the zoning framework
2. Revise high-load utility requirements
3. Establish stricter noise restrictions. 

Staff will report back to Council with their recommendations in December 2026.
