Fire doors only protect people if they close and latch on their own, every single time. This guide explains what gets checked in a fire door inspection, the problems we find most often in Toronto buildings, and how to fix them before a fire inspector or insurer finds them first.

A fire door is not just a heavy door. It is part of a tested assembly: the door, frame, hinges, closer, latch and seals together are what keep fire and smoke out of stairwells and corridors.
In a building fire, most people are hurt by smoke rather than flames. Fire-rated doors in stairwells, corridors, electrical rooms and garbage rooms are designed to hold back both, but only when they are closed and latched. A door that is wedged open, a closer that no longer pulls the door shut, or a latch that does not catch turns a rated opening into a hole in the fire separation.
The Ontario Fire Code requires owners to maintain closures in fire separations so they work as intended, and fire doors in most multi-residential and commercial buildings are part of the building's fire safety plan and regular inspections. NFPA 80, the standard that covers fire door assemblies, calls for them to be inspected and tested at least once a year. Many property managers in Toronto build a yearly fire door check into their maintenance calendar alongside alarm and extinguisher service, and document every door.
Our fire-rated door code requirements guide covers the rules in more detail. This article is the practical side: what an inspection actually looks at, what usually fails, and what repairs are allowed without damaging the door's rating. It is written for condo managers, landlords, facility managers and business owners, not engineers. If you have received a deficiency notice and need doors fixed quickly, send us the list and we will work through it.
From any open position, the door should close fully and latch without anyone pushing it. This is the single most common failure.
The fire rating label on the door and frame proves what the assembly is. Painted-over or removed labels cause problems in inspections.
Replacement hinges, closers and latches have to be suitable for fire doors. The wrong part can void the rating.
These are the points we check on every fire door. They follow the items that NFPA 80 lists for annual inspection.
Fire rating labels on the door and frame are present and readable, not painted over or removed.
No holes, breaks, dents that affect closing, or unauthorised holes from old hardware.
Glass and frames are intact, with fire-rated glazing and no cracks or missing beads.
Correct number of hinges, all screws tight, no excessive wear or sagging.
The closer brings the door from fully open to fully closed and latched, on its own.
The latch engages the strike every time. Active latching, not held by a magnet or friction.
Gaps between door and frame, and under the door, are within the allowed limits.
Smoke seals and intumescent strips are in place and not damaged or painted.
On double doors, the coordinator closes the leaves in the right order so both latch.
No wedges, hooks or unapproved hold-open devices. Approved magnetic hold-opens release on alarm.
No large signs or kick plates that exceed what the rating allows, and no unapproved hardware added.
The door opens easily for egress, and panic hardware works where required.
In Toronto condos, rentals and commercial buildings, the same issues come up again and again.
The closer is weak, set too slow, or fighting a door that rubs. The door stops a few inches from the frame.
The door touches the frame but the latch misses the strike, usually because the door has sagged or the strike moved.
Oil on the door or floor, or a door that slams. A closer that has lost fluid cannot be adjusted back.
Old hardware removed and the holes left open, or damage from carts and impacts.
The door has sagged, the frame has shifted, or the wrong door was installed. Smoke and fire pass through large gaps.
Staff or tenants prop the door for convenience. This is one of the most common fire code issues.
The label was painted over during a renovation or removed with old hardware.
A standard residential lever or a non-rated closer was installed on a fire door.

Doing the checks is half the job. Being able to prove it is the other half.
Your building's fire safety plan and the local fire department are the final authority on how often inspections must happen and how they are recorded. What we see in practice is that buildings with a simple yearly routine, and quick fixes between inspections, rarely end up with long deficiency lists or expensive emergency repairs. For buildings with many doors, a door maintenance contract makes this much easier to manage.
The big question every manager asks. Here is the practical answer.
Adjusting closers, hinges and strikes. Replacing closers, hinges and latches with parts suitable for fire doors. Replacing worn gaskets and seals with matching rated products.
Filling holes, adding hardware, changing locks, adding kick plates or signs. These must follow the door manufacturer's and standard's limits.
Cutting new openings or glass lites in the field, trimming the door beyond allowed limits, using non-rated hardware, or removing labels.
When in doubt, the rule is simple: keep the door as it was tested, and use parts that are suitable for fire doors. If the door has been modified in ways that cannot be corrected, fire-rated door replacement is often the fastest way to get the opening back into compliance.

NFPA 80 calls for fire door assemblies to be inspected and tested at least once a year, and many Ontario buildings follow that schedule as part of their fire safety plan. Check your fire safety plan and local fire department for your building's requirements.
Inspections should be done by someone who knows fire door assemblies and the applicable standards. Many buildings use a door service company together with their fire protection contractor.
Not with a wedge or hook. If a door needs to stay open, an approved hold-open device that releases when the fire alarm activates can be used.
The closer must be suitable for fire doors and sized for the door. A wrong closer can stop the door from latching and cause a deficiency.
It cannot just be replaced with a sticker. Depending on the door, it may be possible to have it re-labelled after inspection, or the door may need to be replaced.
Small holes can often be filled with approved methods such as steel fasteners. Large holes or field modifications usually mean the door must be replaced.
