Emergency board-up, security and make-safe first — permanent repair scheduled after.
The two fire-rated doors a building in Oshawa 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 Oshawa 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 Oshawa 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 Oshawa 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 Oshawa buildings do
The sectors that dominate Oshawa — advanced manufacturing and automotive, healthcare and life sciences, post-secondary education and technology — each put fire-rated doors in different places.
Advanced manufacturing and automotive
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.
Healthcare and life sciences
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.
Post-secondary education and technology
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.
Logistics 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.
Retail 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.
Schools & institutions
Corridor and stair-lobby doors sit on the route everybody uses when the alarm sounds — which is the same route students lean on, wedge and slam. Buildings here span decades, so one corridor can hold three generations of assembly and the first job is establishing what is actually there.

Common questions about fire-rated doors
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.
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.
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.
