Yes. Building Depot is Ontario's Authorized MegaDome Dealer and sells the full MegaDome series (HP, HHP, XP, XL, DB and AR) with Ontario-stamped engineering and manufacturer warranty.

What warranty does Building Depot offer?

MegaDome fabric membranes carry a 15-year prorated warranty, and hot-dip galvanized steel frames are engineered for a 50+ year service life. Foundations and installation carry a 1-year workmanship warranty.

How is a helicopter hangar sized?

By rotor diameter, fuselage length and ground handling clearance for the aircraft you fly, plus room for a second aircraft or a maintenance stand if you need it. Send us the aircraft type and the clearance you want and we'll lay out a footprint.

What kind of door does a helicopter hangar need?

Full-width sliding or bi-fold doors are typical, sized to clear the rotor disc and any tail configuration during ground handling. Door width and clear height are set from the specific aircraft, not a standard opening.

Does an EMS or 24/7 operations hangar need anything different?

Operations running around the clock typically specify an insulated membrane package with heat so crews and aircraft systems aren't working in an unheated bay overnight. Coordination with your operations team on turnaround time and door cycling is part of the design conversation.

What foundation does a helicopter hangar need?

A concrete pad sized to the aircraft weight and any ground support equipment, plus a footing or stem wall carrying the frame. Building Depot designs and pours the foundation and erects the building under one contract.

Can a fabric hangar be used for maintenance work as well as parking?

Yes — a heated bay with translucent membrane daylight and adequate door clearance supports inspection and light maintenance work, not just overnight parking. Tell us what maintenance tasks are planned and we'll size the bay and specify the lighting and heat accordingly.

How does this compare to a conventional steel hangar?

A clear-span fabric hangar avoids interior columns entirely and typically erects faster than rigid-frame steel, while still meeting the same structural design requirements for your site's snow and wind loads. We coordinate the aviation-specific requirements — clearances, apron layout and door operation — with your operator and, where applicable, Transport Canada.

What do you need from us to price a helicopter hangar?

Site address, aircraft type and number of aircraft, door configuration, whether the bay needs to be heated, any maintenance function required, and your target in-service date. That's enough for a preliminary layout and budget.

HELICOPTER HANGARS ONTARIO

Built around the aircraft, not a catalog size.

Engineered fabric helicopter hangars for Ontario corporate, EMS and utility operators — clear-span buildings sized to your rotorcraft, doors sized to your ground handling, installed turnkey by one Ontario team.

SIZED TO YOUR AIRCRAFT

Rotor clearance drives everything.

A helicopter hangar has different clearance needs than a fixed-wing hangar — rotor diameter, tail configuration and ground handling swing radius all shape the footprint and door width. A clear-span fabric building removes interior columns from the equation entirely, so the layout follows the aircraft and the ground crew's routine, not a structural grid.

→Clear-span dimensions sized to rotor diameter and fuselage length
→Door width and height matched to rotor disc clearance
→Stamped engineering for any Ontario snow and wind zone
→Membrane warranty terms confirmed in the issued documents

Sized to the Aircraft

Rotor diameter, fuselage length and ground handling clearance drive the footprint — not a generic hangar size.

Full-Width Doors

Sliding or bi-fold doors sized to clear the rotor disc during taxi and ground handling.

Daylit Inspection Space

A translucent membrane gives crews strong natural light across the aircraft for daily inspection and light maintenance.

Heated Bay Options

Insulated membrane packages and heat sized for EMS, corporate or utility operations running through an Ontario winter.

SIZING THE BUILDING

Aircraft type and ground handling first.

A helicopter hangar is sized around the specific aircraft and how it's handled on the ground — not a generic bay size. These are the inputs we use before any dimension is quoted:

→Aircraft type, rotor diameter and fuselage length
→Number of aircraft the hangar needs to hold at once
→Ground handling clearance required during taxi and turning
→Door type and clearance — sliding or bi-fold, sized to the rotor disc
→Whether the bay needs to be heated for year-round or 24/7 operation
→Any maintenance function beyond overnight parking

Send those details and we will come back with a building size, a foundation approach and a preliminary budget range. Preliminary figures are for budgeting only — final pricing follows engineering, site conditions and the configuration you select.

Single-aircraft bays

Sized tightly around one aircraft with the clearance the operator specifies.

Multi-aircraft hangars

Wider spans for fleet parking, with independent door access to each bay where needed.

Heated maintenance bays

Insulated packages and heat sized for inspection and light maintenance work, not just parking.

Remote and regional sites

Structures scoped for utility and industrial sites without the infrastructure of a major airport.

FOUNDATION & DOOR PACKAGE

The pad and the door move together.

A hangar pad has to carry the aircraft weight and any ground support equipment, and the door has to open wide enough and fast enough for real operations — a slow door on an EMS hangar defeats the purpose of the building. We design the footing, the pad and the door system as one package, then pour it and erect the building with our own crews under one contract.

→Pad designed for aircraft weight and ground support equipment
→Sliding or bi-fold door sized and specified to the rotor disc
→Apron grading coordinated with the hangar foundation
→One contract from excavation through commissioning

See our foundation work

Operator coordination

Siting, clearances and door operation are coordinated with your operator and, where applicable, Transport Canada.

24/7 readiness

EMS and utility operations are designed around fast door cycling and reliable heat, not standard hangar defaults.

SITE & PLANNING CHECKLIST

What we walk through before drawings start.

Apron and drainage

Pad grading and drainage so runoff and de-icing fluid move away from the hangar and adjacent apron.

Ground handling clearance

Taxi and turning space around the hangar sized to the aircraft's rotor disc and tail configuration.

Foundation type

Concrete pad sized to aircraft weight and ground support equipment, with the frame footing designed as one system.

Approvals & coordination

Permit drawings for your municipality and, where applicable, coordination with your operator and Transport Canada on siting and clearances.

Rotorcraft ground handling and apron layout carry different clearance rules than fixed-wing operations. We plan the pad and apron around your aircraft rather than a generic hangar template.

WHO WE BUILD FOR

Different missions, the same clearance problem.

Corporate and private operators

Single or multi-aircraft hangars for company or private helicopters needing weather protection and secure storage.

EMS and air ambulance operators

Heated bays supporting fast turnaround and 24/7 readiness, coordinated with your operations schedule.

Utility and industrial operators

Hangars supporting powerline, forestry and industrial rotorcraft operations at remote or regional sites.

Municipal and regional airports

Hangar capacity added to an existing airport site alongside fixed-wing infrastructure.
