The two fire-rated doors a building in Milton 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 Milton 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 Milton 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 Milton 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 Milton buildings do
The sectors that dominate Milton — distribution centres, logistics, manufacturing — each put fire-rated doors in different places.
Distribution centres
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.
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.
New-build construction
Fire-rated openings are scheduled against the fire separations on the drawings, with the hardware settled before fabrication because nothing can be prepped afterwards. Fire-rated doors are made to order, so the shop sets the date and the install follows it.
Condos & property management
Garbage and chute rooms, storage rooms, the parking-level separation and the suite entries: the four groups an inspection always visits, and the four a manager is asked to produce paperwork for. Across a portfolio it is a scheduling exercise more than a door one.
Hotels & hospitality
Guest-room doors are fire-rated at the corridor and finished on the guest side, hung by the hundred, so a floor is refurbished as a set rather than a door at a time. The kitchen and servery pass-throughs are the wide openings, and those close on shutters.
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.

Common questions about fire-rated doors
How long does a fire-rated door take?
Typically 4–6 weeks to produce a labelled door and frame once the shop drawings are approved, then 1–2 weeks to schedule the job and install it, depending on the size of the project. Certified assemblies are made to order with the hardware prep in the leaf, so the schedule is set by the fabrication rather than the installation. Inspections and most repairs, by contrast, are scheduled in days. Hanging a single labelled door and frame is usually a day on site; a building's worth of rated openings on a new build is scheduled over several weeks with the general contractor.
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.
How often do fire doors have to be inspected in Ontario?
Monthly, and in full once a year. The Ontario Fire Code requires doors in fire separations to be inspected monthly and kept in working order, with any deficiency corrected. NFPA 80 adds a full inspection and test of every assembly at least once a year, documented and kept on site — it sets out what has to be checked and what counts as a failure. Our inspection page covers what that visit involves.
