Land use and zoning

In addition to conducting airport-specific reviews, the GTAA forwards all development proposals that meet NAV CANADA (Canadian civil air navigation agency) review requirements for their assessment and comments with regard to potential impacts on navigation, communication and surveillance equipment operating at the airport.

Height and land use policies compliance

Any developments—including but not limited to, buildings, cell towers, antennae, high light masts etc. that are located in areas affected by federal Airport Zoning Regulations, Obstacle Limitation Surfaces, International Civil Aviation Organizations Type A Surfaces or the Airport Operating Area (AOA) and land use compatibility policies—must be reviewed as part of a municipal site plan review process or prior to starting any construction activities for those developments that are not subject to municipal site plan approval.

Compliance review application process

To apply for a compliance review, please send the following items to the GTAA Land Use Planning department at landuse.planning@gtaa.com:

  1. A completed Zoning Compliance Review Request Form (PDF, 143 KB)
  2. A site plan drawing, in CADD (preferred) or PDF format, showing the footprint and the coordinates of the outside corners of the proposed building or centre point coordinate for structures such as flag poles, light masts, cell towers, etc. When available, provide the coordinates in the following format: 6 degrees UTM (Universal Transverse Mercator) (Zone 17) expressed in metres and based on NAD 27-1974 adjustment (horizontal); GSC-1978 Southern Ontario adjustment (vertical).
  3. If the coordinates are not available, please provide a site plan with topographic base map information that can be used within the GTAA’s mapping system to position the structure with reference to adjacent buildings, road curbs/centerlines, existing fences, etc. For the GTAA “on site” projects, submit the site plan in MicroStation V8 format.
  4. Finished Floor Elevation (F.F.E.) or ground elevation expressed in metres Above Sea Level (m. A.S.L.).
  5. For a linear group of structures, provide a spreadsheet containing coordinates, ground elevation expressed in m.A.S.L. and height.
  6. Provide the top elevation of the highest structure’s/building’s component (m.A.S.L.) or height of the structures including any rooftop HVAC units, access ladders, railings/parapets or other architectural features.
  7. For projects on airport lands, or in an immediate vicinity of the airport, include design information to help assess compliance with restrictions associated with NAV CANADA’s navigation, communication and surveillance facilities. Design information to include:
  • Exterior walls and roofing materials being used
  • Technical specifications of solar roof panels (manufacturer’s specs)
  • Exterior lighting/illumination systems
  • Rooftop antennae and/or radio transmitter locations along with their power output and broadcast frequencies

Should there be a design change (location adjustment, height increase, architectural redesign, etc.) subsequent to receiving GTAA’s and NAV CANADA’s comments, the proponent must resubmit the proposal for re-evaluation and updated comments.

Crane Permits

Both on and off airport construction projects that require use of crane(s) should apply for a crane permit.

Processing Time

While the GTAA review part may take up to two weeks, NAV CANADA’s independent review may take 12 weeks or more depending on the complexity of the project and current workload. To avoid delays to your development plans, please submit your zoning compliance review request at least four months the before intended start of construction, or as soon as possible.
