Oakville council has unanimously approved a one-year moratorium on new data-centre development across specifically zoned lands in the town, a measure adopted swiftly during a special council meeting after a motion was introduced only one day earlier.
Immediate pause to review land-use and impacts
The interim control bylaw takes effect immediately and bars construction of data centres on identified parcels of land, including portions of the Parkway Belt West, a provincial corridor reserved for highways and utilities. The measure gives the town time to examine its land-use planning rules and to assess how data centres might cause “adverse effects,” including noise, vibration and emissions.
Council members framed the moratorium as a necessary pause to ensure development does not outpace policy. During the meeting, Coun. Tom Adams noted the technical and resource-intensive nature of such facilities, saying the bylaw provides the municipality with the space to do the work properly.
“These projects are complex, they’re energy-intensive. An interim control bylaw gives us the breathing room to do this work properly. It ensures that development does not get ahead of policy.” — Coun. Tom Adams
What sparked the rapid move
The decision followed publicised interest from BUZZ High Performance Computing Inc., which has told investors it plans to build what it called “one of Canada’s largest AI gigafactories” in Oakville’s Ward 6. While the town has not received a formal planning application, councillors said the company had approached municipal staff.
In a June earnings call, the CEO of HIVE Digital Technologies Ltd., BUZZ’s bitcoin-mining parent, described the Oakville venture as a key project estimated to cost US$3.5 billion and sized at 320 megawatts. He also addressed concerns about water use, saying any data centre would use a closed-loop system and require upgrades to regional water lines.
“There's a lot of NIMBYism. ‘Oh, no, they're going to sap up and use all the water.’ No, it doesn't work like that.” — Aydin Kilic, CEO, HIVE Digital Technologies Ltd.
Scope of the bylaw and next steps
The interim control bylaw specifically targets lands already zoned for industrial or utility uses where data-centre development might otherwise proceed. Council said the one-year timeframe will allow municipal staff to:
- review existing land-use planning policies;
- assess potential environmental and community impacts such as noise, vibration and emissions;
- consider zoning and servicing implications on provincially designated corridors like the Parkway Belt West.
Council did not provide additional details on a timetable for the review or the precise list of parcels covered beyond noting the inclusion of parts of the Parkway Belt West. The town is about 35 kilometres west of Toronto, placing the potential development squarely within an area experiencing growing pressure from digital infrastructure investment.
| Item | Detail |
|---|---|
| Moratorium length | One year |
| Proposed project size (reported) | 320 megawatts |
| Estimated project cost (reported) | US$3.5 billion |
| Area affected | Specifically zoned lands; parts of the Parkway Belt West |
Across the province and country, several municipalities have recently moved to pause data-centre approvals while they develop policies to address power demands, water use and local impacts. Oakville’s swift, unanimous decision underscores growing municipal concern about how large-scale data infrastructure projects intersect with land-use planning, municipal services and community expectations.
For Oakville residents, the bylaw buys time for detailed study and public consultation before any application for a major data centre would proceed. It also signals council’s intent to closely scrutinize proposals that could change industrial land use and municipal servicing needs in the coming years.
