Airport Zoning Regulation (AZR)

Brampton Airport Zoning Regulations (AZR)

To keep airplanes safe and help the airport function well long-term, the area around the airport must be kept free from obstacles. Transport Canada sets rules for how high objects can extend into the airspace. This airspace can be protected through Airport Zoning Regulations (AZR), as per the Aeronautics Act.

An AZR is a set of rules that sets limits on how tall buildings, structures, and even trees can be near the airport. Like a zoning by-law, it helps to prevent incompatible land use around the airport. However, unlike regular zoning, an AZR also considers the airspace and sets rules for things like developments that attract wildlife or interfere with airplane communication and navigation, and wind turbines.

Brampton Airport Zoning Regulations Now In Effect

By-law 2025-111 (AZR By-law) was passed by Council on November 25, 2025 and now in full force and effect. A copy of the By-law is provided below in the resources section.

Background

In 2019, the Brampton Airport asked the Town to work with the Airport to create the Airport Zoning Regulation (AZR) to protect the airspace around the airport and make flying safer. Council asked staff (as per Staff Report 2019-013 dated January 15, 2019) to work on this request, hold public consultation and report back.

Since 2021, the Town staff has worked with the Brampton Airport and Transport Canada to create the necessary framework for the AZR. In 2024, an agreement between the Town and Transport Canada was updated and signed, allowing the airport to start the application process.

In January 2025, the Town shared the application with the public, internal departments and external agencies for feedback. The AZR will not be part of the Town’s Comprehensive Zoning By-law 2006-50 but will act as an overlay on it. A public meeting was held on April 15th, 2025, with a report to Planning and Development Committee on November 11, 2025 and the By-law was passed by Council on November 25, 2025.

FAQ (Updated as of December 1, 2025)

What is an AZR?

An AZR is a set of rules that make sure that development near an airport does not interfere with the safe operation of aircraft. These regulations:

Limit how tall things like buildings and trees can be;
Prevent development that attracts birds;
Prevent land uses that interfere with airplane communication or navigation

Why are AZRs being established now?

The Town of Caledon is anticipating a lot of growth in the coming years. Since 2019, the Brampton Airport, Transport Canada, and the Town of Caledon have been working together to create the AZRs to ensure that future development near the airport does not affect the safe operation of aircraft.

What are the impacts to future development and property owners?

The AZR will affect future development in certain areas of the Town, especially near the airport runways. Restrictions will include limits on how tall buildings can be, which could affect high-density development, as well as other structures like silos, stormwater ponds, and communication towers.

Is the Brampton Airport anticipating any expansions?

The Brampton Airport has stated that there are no current plans to expand the runways. Any future changes or expansions would require updating the AZR, which would be a more detailed process. No development is happening at the airport right now either, the AZR are only meant to protect the airport as it is now.

How can I check to see how my property is affected by the proposed AZRs?

Aside from reading the materials on the website, you can check your property’s maximum building height here. In most cases, the height limit is higher in the AZR (such as 35 meters), but any development must still follow the Town’s existing zoning rules (such as 10.5 meters).

What happens in the event the airport stops operations?

If the Brampton Airport stops operating and is no longer considered an airport under the Aeronautics Act, the AZR will be cancelled.

Who I speak to if I have any questions?

To see if your property is affected by AZRs, use the mapping tool. If you need help with the tool, or have questions about what this means for you, contact planning staff at planning@caledon.ca or 905-584-2272.

If you want to buy land within the AZR, or plan construction close to the maximum height allowed by the proposed AZR, it’s recommend you contact the Brampton Airport. It’s recommended, given the complex rules, that you work with professionals such as a registered professional planner and/or solicitor.
