A fire door that doesn’t close properly, has excessive gaps, or has a failed smoke seal isn’t just a maintenance issue, it’s a code violation and a liability. In Ontario, fire doors must meet strict requirements under the Ontario Building Code and the Ontario Fire Code, and must be inspected regularly.
Fire Door Inspection Services Toronto & GTA
Under Ontario’s Fire Code (O. Reg. 213/07), building owners are required to ensure fire doors are maintained in proper working order and inspected regularly. Many commercial and multi-residential buildings require annual fire door inspections as part of their fire safety plan — and failing an inspection can result in orders, fines, or closure.
Delet provides professional fire door inspections for commercial buildings, condominiums, apartment buildings, schools, hospitals, and industrial facilities across Toronto and the GTA.
What our fire door inspection covers:
- Door leaf and frame condition: warping, damage, corrosion
- Gap measurements (bottom: max 6mm; sides and top: max 3mm per Ontario code)
- Smoke seal and intumescent seal condition
- Self-closer operation: full positive latch on release
- Hinge count, condition, and fastener security
- Glazing and vision panel integrity (fire-rated glass only)
- Latch and lockset engagement
- Signage and labelling compliance
- Hold-open device compliance (electromagnetic only: wedges and props are code violations)
- ULC label verification on door leaf and hardware
After inspection: We provide a written report documenting each door’s status, any deficiencies found, and recommended repairs — suitable for your fire safety plan records and building inspection logs.

Fire Door Requirements in Ontario
Fire door repairs should be a top priority as inadequate fire doors can endanger people’s lives and result in extensive damage to your building.
Fire doors in Ontario are governed by two primary codes:
- Ontario Building Code (OBC) — sets the construction and installation standards for fire-rated assemblies, including minimum fire resistance ratings by building occupancy type and location.
- Ontario Fire Code (O. Reg. 213/07) — governs the ongoing maintenance and inspection of fire protection systems, including fire doors, in existing buildings.
Key Ontario fire door requirements:
| Requirement | Standard |
|---|---|
| Bottom gap (door to floor) | Maximum 6mm |
| Side and top gaps | Maximum 3mm |
| Self-closing | Must latch positively from any open position |
| Smoke seals | Required on all fire doors in most applications |
| Hold-open devices | Electromagnetic only – mechanical wedges are prohibited |
| Vision panels | Fire-rated glass only – standard glass not permitted |
| Hardware | Must be ULC-listed and compatible with the fire door rating |
| Labels | ULC certification label must be present and legible on door and frame |
Fire door ratings correspond to how long the assembly must resist fire penetration:
- 20-minute – corridor and room separation doors
- 45-minute – vertical shaft enclosures, exit stairwells in some applications
- 60-minute – occupancy separations, service rooms
- 90-minute – fire separations between major occupancies
Delet’s technicians are fully versed in Ontario’s fire door requirements and ensure every repair maintains or restores the door’s certified fire rating.

Fire Door Repair & Inspection for Every Building Type in Toronto & the GTA
Ontario’s fire door requirements apply across virtually every commercial occupancy. The inspection frequency, door ratings required, and consequences of non-compliance vary by building type — which is why sector experience matters. Delet regularly works with:
Condominiums & Apartment Buildings
High-rise and mid-rise residential buildings are among the most heavily regulated for fire door compliance in Ontario. Suite entry doors in fire-rated corridor assemblies, stairwell doors, garbage room doors, and electrical/mechanical room doors all require regular maintenance and inspection. Property managers and condo corporations are directly accountable under the Ontario Fire Code for the condition of fire doors in common areas. We work with property management companies across the GTA on both reactive repairs and scheduled annual inspection programs.
Hospitals & Long-Term Care Facilities
Healthcare facilities face the strictest fire door compliance requirements of any building type, patients and residents cannot self-evacuate, making compartmentalization through properly functioning fire doors critical. Accreditation bodies and the Ontario Fire Marshal conduct regular inspections, and deficiencies must be corrected quickly. Delet schedules healthcare repairs to minimize disruption to operations and can work after hours or in sections to keep wards functional.
Schools & Universities
Educational institutions have large occupant loads and complex fire compartmentalization requirements. Corridor fire doors, gymnasium and auditorium separations, stairwell doors, and service room assemblies all require maintenance. Boards of education and facilities departments often manage dozens of buildings — we support multi-site inspection and repair programs for school boards across the GTA.
Hotels & Hospitality
Hotel guestroom corridor doors are typically fire-rated assemblies and must self-close and latch positively. With hundreds of doors per property, wear is constant and inspections are mandatory. We work with hotel facilities teams on both emergency repairs and scheduled maintenance to keep guest corridors compliant without disrupting occupancy.
Office Buildings & Highrise Commercial
Stairwell enclosure doors, elevator lobby separations, and mechanical room fire doors in office towers require regular inspection and maintenance. Building owners and property managers face direct liability for non-compliant fire doors during lease audits, insurance renewals, and fire marshal inspections. Delet provides documented inspection reports suitable for building compliance records.
Retail & Mixed-Use Developments
Fire separations between retail tenancies and between retail and residential or parking occupancies require rated door assemblies. Tenant turnover and high foot traffic accelerate wear on hardware and seals. We work with both landlords and tenants on fire door compliance as part of leasehold improvement and ongoing maintenance programs.
Industrial & Warehouse Facilities
Occupancy separations between warehousing, manufacturing, and office areas typically require fire-rated door assemblies with specific ratings based on the hazard level of adjacent occupancies. Loading dock fire doors and fire shutters also fall within our scope. Industrial environments are harder on hardware — we stock heavy-duty replacement components for high-abuse applications.
Parking Structures & Podium Buildings
Doors between parking garages and occupied building areas are among the most consistently non-compliant we encounter — often propped open, frequently damaged by vehicles, and subject to accelerated corrosion from road salt and exhaust. These doors are also among the highest-risk: a garage fire that breaches into an occupied floor is catastrophic. We treat parking garage fire door repairs as priority calls.
Retirement Homes & Long-Term Care
Provincially licensed retirement homes and long-term care facilities are subject to regular fire safety inspections by the Office of the Fire Marshal and Retirement Homes Regulatory Authority (RHRA). Non-compliant fire doors can trigger immediate orders that affect licensing. We understand the urgency of compliance in these settings and prioritize rapid response.
Multi-Site Property Management
Facilities teams and property managers overseeing multiple buildings benefit from a single trusted contractor for fire door repair and inspection across their entire portfolio. Delet offers priority response agreements and consolidated reporting for multi-site clients — one call, one relationship, consistent documentation across all properties.
