The number sounds enormous first: roughly 20 megawatts of electrical capacity for a proposed two-storey data centre at 3110 South Service Road, the former Tucker's Marketplace site.
That has helped turn the project into a much bigger Burlington argument about electricity, land and who gets a say when a new kind of industrial use arrives.
But the City's current application page makes an important distinction. Based on the information submitted, this is a general-purpose data centre for colocation, cloud computing, storage, networks and data processing. The City says it is not a purpose-built AI or hyperscale facility.
Why that distinction matters
Large AI-focused campuses can be dramatically bigger. Burlington's page contrasts this proposal with hyperscale facilities that can require 100 megawatts or more and may use liquid or water cooling. The South Service Road proposal is expected to be air cooled.
That does not make the local questions disappear. A 20-megawatt request is still significant enough that Burlington has been discussing electricity capacity, employment value, land-use compatibility and community benefit as it considers how future data centres should be handled.
The unusual part is the approval process
The property is already in an area where a data centre is a permitted use. That means the current application is a site-plan review, focused on details such as the building, parking, landscaping, access and servicing rather than a council vote over whether a data centre is allowed there at all.
The City says site-plan decisions are delegated to staff under Ontario's Planning Act. Council cannot simply direct staff to refuse an otherwise permitted use.
That is why the bigger political fight has shifted forward. In July, council asked staff to return in December with a broader framework for how Burlington should handle data centres, including possible guidelines, bylaw changes, public engagement and advocacy.
So what happens next?
The South Service Road application remains under review. Staff and outside agencies still have to examine the technical details. Separately, Burlington is now working on rules for whatever proposal comes after this one.
The immediate question is not simply whether Burlington gets an "AI data centre." The more useful question is what a 20-megawatt general-purpose facility means for this site, and whether the city's rules are ready before the next, potentially much larger, application arrives.
