The phrase that matters is positive latching, and it is stricter than it sounds. It does not mean the door swings shut. It means the latch bolt engages the strike, on its own, from a full open position, with nobody helping. A door that closes and rests against the strike has failed, and it has failed in the way that counts: pressure from a fire pushes it open again.
Ontario’s Fire Code requires the closures in a fire separation to be kept in operating condition, and forbids them being obstructed, blocked or wedged open. Both halves get found. Whitby Fire and Emergency Services will write up a wedged stairwell or refuse-room door in a routine inspection, and the propping is rarely laziness — it is usually a door wound up so hard nobody can get a cart through it. Where a door genuinely has to stand open, a hold-open tied into the fire alarm is the version that is allowed. A doorstop is not, and neither is a fire extinguisher on the floor or cardboard folded into the latch.
We take these buildings as a list. Every self-closing device released from wide open. Latch speed and closer sizing corrected where the door arrives without enough to engage the bolt. Strike, latch, gasketing and clearance sorted where the leaf is not seating. Dead units replaced and hold-opens tested against an actual release. Then a written record of what was found and corrected, for the fire safety plan file.

Fire Door Closers & Positive-Latching Repairs — your questions
What exactly does positive latching mean for our doors?
It means the latch bolt actually engages the strike when the door closes on its own, with nobody pushing it — not that the door merely swings shut. A door resting against the strike has failed the test. That is the single thing we check on every rated opening, and we check it from a full open position, because a door that latches from halfway can still fail from wide open.
Can you do a whole Whitby building at once?
That is where this work makes the most sense. Walking the whole rated list in one visit means the adjustments are consistent, we see the patterns — a whole stairwell set too slow, one floor of strikes out of line — and you get a single written record rather than a year of separate calls.
The arena’s cross-corridor doors are held open all day. Is that a problem?
Only if nothing releases them. Held open on magnets wired to the fire alarm, that is exactly how a busy assembly building is supposed to work. Held open on a doorstop or a wedge, it is a violation and the separation does not exist. We check what is actually holding each door, and fit the released version where the wedge was.
