The buildings here are mostly logistics, warehousing, and storage, advanced manufacturing and retail trade and commercial services, and each puts different demands on a door: traffic volume, insurance and fire requirements, and how much downtime an opening can afford. Ajax’s 126,666 residents keep those buildings busy.

Ajax is roughly a 55-minute run from our Mississauga shop — less if a technician is already in the area — so a truck is usually on site the same day.
Emergency board-up, security and make-safe first — permanent repair scheduled after.
The two fire-rated doors a building in Ajax uses — steel and wood
A fire door is not a door with a rating written on it. It is a tested assembly — leaf, frame, hinges, closer, latch and any glazing — certified together by a body such as ULC or UL, and it performs as certified only while every part of it stays as it was listed. Which of the two materials goes into a given Ajax opening is settled by where the door sits in the building rather than by budget: steel where the door is a tool, mineral-core wood where the door is part of the interior.
Where a building in Ajax carries fire-rated openings
The rating belongs to the wall first. The Ontario Building Code assigns a fire-resistance rating to a fire separation, and the closure in it — the door — gets a matching rating. In Ajax that lands on the same handful of openings in almost every building, and the count is usually higher than the owner expects.

Fire-rated openings for the work Ajax buildings do
The sectors that dominate Ajax — logistics, warehousing, and storage, advanced manufacturing, retail trade and commercial services — each put fire-rated doors in different places.
Logistics, warehousing, and storage
The separation here is between the racked floor and the office block: cross-corridor and office-entry doors in a fire-rated wall, and a shipping opening usually too wide for a leaf, which closes on a rolling fire shutter instead. What fails is a frame knocked out of line by a pallet truck until the latch stops throwing.
Advanced manufacturing
The walls that carry a rating are the ones around the process area and the electrical room, and the doors in them are steel because the leaf is in a plant. The recurring finding is a fire-rated door propped open for airflow or cable runs — the legal version of that is a magnetic hold- open tied to the alarm.
Retail trade and commercial services
A unit in a plaza or mall carries fire-rated openings the tenant never thinks about: the back-of-house door onto the service corridor, the stock-room separation, and the mall front itself, which on a fire-rated common area closes with a shutter or curtain on alarm rather than with the shopfront glass.
Healthcare and institutional
Smoke and fire compartments cut the floor plate into sections, and those doors have to work for a bed and a crash cart as well as for the separation. Cross-corridor pairs run on hold-opens tied to the alarm, and the finished wings take wood because the door is part of the ward.
Food & pharma processing
The rating sits on the separation between production and the rest of the plant, and it has to survive washdown and a sanitation schedule. Gasketing painted over or torn out during cleaning is the commonest deficiency, and putting it back is a listing question rather than a maintenance one.
Offices & business parks
Stair doors are the largest single group in the building, floor by floor, usually temperature-rise rated and on exit devices. After a fit-out the two findings are always the same: a card reader drilled into a fire-rated leaf, and clearances thrown out by a new floor finish.

Common questions about fire-rated doors
Can a fire door be held open?
Only by a device that releases it. A fire-rated door has to close and latch by itself when the alarm sounds, so it cannot be wedged, tied or hooked open — but it can be held open legally on a magnetic hold-open or an electrified closer tied into the fire alarm, which releases the door on alarm. That is the correct fix for a door people keep propping, and it is usually less expensive than the deficiency it prevents.
What fire ratings do doors come in?
20, 45, 60, 90 and 180 minutes are the standard ratings. Which one an opening needs is set by the fire separation it sits in, not by preference: the Ontario Building Code assigns a fire-resistance rating to the wall, and the door in it gets a matching closure rating. Some openings, notably in exit stairs, also carry a temperature-rise limit so the far face of the door stays cool enough to pass.
Can you repair a fire door, or does it have to be replaced?
Many deficiencies are repairable within the listing — replacing a closer or latch with a certified equivalent, refitting hardware, correcting clearances, repairing a frame, and re-labelling in some cases. What cannot be repaired is an unauthorised field modification: a hole cut for a lock, a lite kit added after the fact, or a leaf cut down to fit a new floor. Those are replacement, because there is no legitimate way to restore the listing.
