The two fire-rated doors a building in Cambridge 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 Cambridge 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 Cambridge 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 Cambridge 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 Cambridge buildings do
The sectors that dominate Cambridge — advanced manufacturing, logistics, transportation and warehousing, food and beverage processing — each put fire-rated doors in different places.
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.
Logistics, transportation and warehousing
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.
Food and beverage 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.
Commercial retail and 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.
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.
General contractors & new builds
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.

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.
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.
What is a fire-rated door?
A complete assembly — door, frame, hinges, closer, latch and any glazing — tested and certified to hold a fire back for a set time. It carries a label from a certification body such as ULC or UL, and the label belongs to the whole assembly rather than to the leaf. Change one certified part for an uncertified one and the opening is no longer fire-rated, which is why fire doors are specified as assemblies and never assembled from spare parts.
