The legal requirement
Division B, Part 6 of the Ontario Fire Code requires that fire alarm systems be inspected, tested, and maintained in conformance with CAN/ULC-S536. The obligation sits with the building owner — not the tenant, not the property manager, and not the alarm monitoring company. Delegating the work to a contractor does not delegate the liability.
Annual inspection is the headline requirement, but S536 also prescribes monthly and, for certain devices, semi-annual checks. A building that only sees a technician once a year is almost always out of compliance on the monthly items.
What gets tested annually
- Every initiating device: smoke detectors, heat detectors, manual pull stations, sprinkler flow and supervisory switches, duct detectors.
- Every audible and visual signalling appliance, verified for sound pressure level and synchronisation.
- The control unit, transponders, annunciators, and all field wiring supervision (open, ground fault, short circuit).
- Primary and secondary power supplies, including a full battery load and capacity test.
- Off-premise signal transmission to the monitoring station, with the receiving centre confirming each signal type.
- Ancillary device operation: door hold-opens, elevator recall, HVAC shutdown, magnetic locks, fan control.
- Emergency voice communication and firefighters' telephone circuits where installed.
Who is allowed to do it
S536 requires the work to be performed by a qualified person as defined by the standard. In practice, verification of that qualification means a technician holding CFAA registration (Canadian Fire Alarm Association) or equivalent documented training on the specific equipment installed.
Fire departments routinely ask for the technician's certification number alongside the report. If your report has no name, no number, and no signature, expect it to be rejected.
Inspection versus verification
Annual inspection under S536 is not the same as verification under CAN/ULC-S537. Verification is a one-time, end-to-end proof that a newly installed or modified system was installed to the approved drawings and functions as designed. Any device addition, panel replacement, or wiring change triggers a partial verification of the affected circuits.
A common and expensive mistake: a contractor adds detectors during a tenant fit-up, nobody verifies, and the deficiency surfaces two years later during a fire department inspection.
Recordkeeping the inspector will ask for
- The most recent annual inspection and test report, retained on site for a minimum of two years.
- Monthly test records signed by the building's designated person.
- The verification report from original installation and from every subsequent modification.
- A current list of outstanding deficiencies with dates, along with proof of correction for closed items.
- Documentation of any impairment periods and the fire watch measures taken.
Deficiencies that stop the clock
An annual inspection report that lists uncorrected deficiencies does not make the building compliant — it documents non-compliance. Fire departments increasingly issue orders based on the contractor's own report. The safest position is to have deficiency repair pricing quoted at the time of inspection so corrections happen inside the same maintenance window.
