Calgary’s data centre pause hangs on one undefined word

A Calgary data centre moratorium, proposed in a council motion, would pause rezoning for large-scale data centres until March 2027, and the business impact depends on a size line nobody has drawn yet.

The Calgary data centre moratorium is a notice of motion, not a bylaw.
It freezes rezoning decisions for large-scale sites only.
The word “large-scale” has no number attached, and that gap decides who is affected.

The Calgary data centre moratorium went on the record on October 28, 2026, as a notice of motion headed for the city’s Executive Committee on November 3. It asks administration to stop bringing new land use redesignation applications for large-scale data centres to council until new bylaw rules are ready. Our reading: the pause itself is sensible sequencing, but council should put a number on “large-scale” before it votes, because the motion’s own text says smaller data centres are ordinary local businesses.

What does the Calgary data centre moratorium actually do?

It directs the chief administrative officer to stop bringing new land use redesignation applications for large-scale data centres to council for decision. The pause lasts until a report and possible amendments to Land Use Bylaw 1P2007 come back, targeted for the March 2027 public hearing. It does not ban data centres, and it does not touch small or medium sites by its own terms.

The notice of motion is sponsored by Councillors Wyness, Dhaliwal, Yule and Pantazopoulos and Mayor Farkas. Its operative clauses add three more pieces of work: reaffirming water servicing terms with regional partners, a report on risks and possible tax and bylaw changes, and a report on cumulative water security. The last two are due no later than Q4 2027.

One detail matters more than the headline. The bylaw currently has no definition of a data centre at all, so every proposal is judged against general rules. That is the real problem the motion is trying to fix.

Which Calgary businesses are affected by the data centre pause?

Mainly developers and operators seeking to rezone land for very large campuses. A Calgary firm renting rack space, running a server room or buying cloud capacity is not the target. The motion itself says small and medium-scale data centres have needs comparable to other commercial and industrial businesses and belong to the city’s ordinary business base.

The catch is that the motion never says where medium ends and large begins. Megawatts, floor area, water draw: any of these could set the line, and each would catch a different set of projects. Until the March 2027 report proposes a definition, a mid-sized edge facility or a local AI hosting company cannot know for certain which side it sits on.

Regional customers also have a quieter exposure. Calgary supplies water to neighbouring municipalities, and the existing servicing agreement already requires them to notify the city when a new large customer exceeds one megalitre a day of potable water or wastewater flow. The motion asks the city to reaffirm those terms, which puts water-cooled projects just outside city limits on notice too.

How does Calgary compare with other Canadian municipalities?

Calgary is a follower here. The motion lists five municipalities that have already passed temporary planning restrictions, one that paused zoning changes, and three that are rewriting their bylaws. Together they span six provinces, which tells a site selector that local land use rules now belong in data centre risk planning well beyond Alberta.

Source: City of Calgary notice of motion EC2026-01010, as listed in its preamble. Text summary: five municipalities restrict applications, one paused zoning changes, three are reviewing bylaws, and Calgary’s motion is proposed.

Is a pause the right call for Calgary?

Yes, with one change. Defining a use before approving more of it is ordinary planning practice, and a bylaw with no data centre definition invites case-by-case fights. But a pause tied to an undefined term shifts uncertainty onto every mid-sized project. Council should ask for an interim threshold on November 3, even a rough one.

The reason is practical. Alberta’s broader push for AI infrastructure, covered in our look at data centre projects in Olds and Bonnyville, means capital will move to whichever municipality offers clear rules first. A clear interim line keeps the small operators the motion praises out of a queue meant for campuses.

The other reading deserves a fair hearing. Some will argue any number set now would be arbitrary and quickly gamed, and that a short, clean pause is better than a hurried definition. That is a reasonable position. We still read it our way, because the motion’s own preamble already distinguishes scales in words, so turning that distinction into a provisional figure is a smaller step than it looks.

Fine Print

• Instrument: notice of motion, report EC2026-01010, item 5.2.2.
• Status: proposed; technical review at Executive Committee on November 3, 2026. Not in force.
• Who decides: Calgary City Council; the chief administrative officer carries out the direction.
• Who it applies to: new land use redesignation applications for large-scale data centres.
• What changes: those applications stop reaching council until the March 2027 report on Land Use Bylaw 1P2007.
• Still undecided: the size threshold for “large-scale”, and whether any tax bylaw changes follow.

What should businesses do before November 3?

Check whether any planned Calgary site needs rezoning, then plan as if the answer arrives no earlier than March 2027. Firms that only buy hosting or colocation need no action beyond asking their provider about expansion plans. Developers with live applications should confirm with the city whether theirs counts as large-scale under the motion.

1. List every Calgary or regional site in your plans that would need a land use redesignation.
2. Write down its expected power draw and daily water use, so you are ready when a threshold is proposed.
3. If your project sits in a regional municipality served by Calgary water, check it against the one megalitre a day notification trigger.
4. If you rent capacity, ask your provider whether its next Calgary expansion depends on rezoning.

National principles for data centre power, which we covered in Canada’s data centre power principles, will not settle a Calgary zoning question. The municipal layer now matters on its own, as the AI data centres in Canada hub tracks.

FAQ

Has Calgary banned data centres?

No. The motion proposes a temporary moratorium on bringing new rezoning applications for large-scale data centres to council. It is a notice of motion going to Executive Committee on November 3, 2026, and is not in force.

Does the Calgary data centre moratorium affect small data centres?

The motion suggests it does not. It says small and medium-scale data centres have needs comparable to other commercial businesses, but it does not set a size threshold. The motion text leaves that to the March 2027 report.

When will Calgary define data centres in its land use bylaw?

The motion asks for proposed amendments to Land Use Bylaw 1P2007 at the March 2027 public hearing, with reports on infrastructure and water security no later than Q4 2027.

Which other Canadian municipalities have restricted data centres?

The motion lists Rocky View County, Oakville, Cumberland, Saskatoon and Mississauga as having passed temporary restrictions, with Miramichi pausing zoning changes and Essex County, Terrace and Mountain View reviewing bylaws.

The next date is November 3, 2026, when Executive Committee reviews the motion. Before then, any business with a Calgary site that needs rezoning should have its power and water figures written down.
