Ontario Fire Code ULC-S536-19: 2026 Annual Inspection Rules for Multi-Unit Rentals
Your fire alarm inspection report has to follow CAN/ULC-S536-19 in 2026. Anything tested under the older edition since January 1 is no longer legally compliant, and municipalities now have Administrative Monetary Penalty authority for Fire Code violations.
Bottom line
- O. Reg. 87/25 amended Ontario’s Fire Code to adopt CAN/ULC-S536-19 for annual inspections and CAN/ULC-S537-19 for verification on new or altered systems. In force January 1, 2026.
- Battery load testing is required — voltage checks alone are not enough. Monthly and annual inspections use ULC-prescribed forms with every tested device listed.
- Owner sign-off on completed deficiencies is mandatory. Municipalities can now issue Administrative Monetary Penalties for Fire Code violations.
What changed on January 1, 2026
Ontario amended the Fire Code through O. Reg. 87/25 (made in 2025, in force January 1, 2026) under the parent Fire Code regulation, O. Reg. 213/07. The amendment adopts the national standards CAN/ULC-S536 and CAN/ULC-S537 for fire alarm inspection and verification. Industry sources confirm the in-force editions are the 2019 versions (CAN/ULC-S536-19 and CAN/ULC-S537-19). The Ontario Association of Fire Chiefs summary for apartment owners covers the broader changes in O. Reg. 87/25, including exit doors and CO alarms.
Who this applies to
ULC-S536-19 applies to buildings with monitored fire alarm systems — most multi-unit residential buildings, mixed-use buildings, MURBs, and commercial towers. Single-family rentals are not in scope for S536; they follow smoke and carbon monoxide alarm rules under separate sections of the Fire Code. Practical rule of thumb: if your building has a fire alarm panel that monitors detection devices on every floor, S536-19 applies to the annual inspection.
What the new standard adds vs. the older one
| Element | Older edition | CAN/ULC-S536-19 |
|---|---|---|
| Device testing | Sampled / functional groupings | Every device individually |
| Battery testing | Voltage check sufficient | Functional load test required |
| Report format | Vendor-supplied templates | ULC-prescribed inspection & testing forms |
| Deficiencies vs. recommendations | Often blended | Clear separation required |
| Technician records | Variable | Names, dates, inspection durations |
| Owner signoff | Not consistently required | Mandatory on completed deficiencies |
What the annual inspection now looks like
Under S536-19, the technician tests every detection device, every signal device, every power supply, and every voice/wireless module individually. Each battery gets a functional load test confirming it can power the system to its rated capacity, with the reading recorded in the inspection report. The report uses the official ULC-S536:2019 forms, lists every tested device with the outcome, and clearly separates deficiencies from recommendations. Technician attendance is logged with names, dates, and inspection duration.
Practical impact: industry guidance reports that S536-19 inspections take 20% to 35% longer than under the previous standard, with the cost passed through from the contractor. Book a longer service window than you did in 2025 to avoid year-end crunches.
Ask for the certification document. Contractors must hold ULC certification covering the 2019 edition specifically. A contractor still operating on an older S536 certification cannot produce a legally compliant inspection report for 2026 onward. Verify before they invoice.
Monthly inspections and ongoing recordkeeping
S536-19 also formalises the monthly inspection. Each month, the assigned person walks the building, confirms the fire alarm panel status, checks for trouble and supervisory signals, and records the findings on the ULC-prescribed monthly form. The owner retains twelve months of these logs at the building, available for fire-inspector review on request. Missing months cannot be back-filled at the annual inspection.
Owner sign-off: what you are attesting to
After the annual inspection identifies deficiencies, you have an obligation to resolve them. Once each cited deficiency is corrected, you sign the owner-acknowledgement section of the report to attest to the corrective action. The signed report becomes the documentary record fire inspectors will look at in any future enforcement review.
Treat the signoff as a sworn statement. Do not sign deficiencies as resolved unless they are. Falsified acknowledgements expose owners to prosecution under the Fire Protection and Prevention Act in addition to municipal AMPs.
Penalties: AMPs and FPPA prosecution
Effective January 1, 2026, Ontario municipalities have explicit authority to issue Administrative Monetary Penalties for Fire Code violations against tenants, owners, corporations, and other responsible parties. AMP schedules are set by individual municipal bylaws. The Fire Protection and Prevention Act, 1997 remains available for more serious offences, with statutory maximums up to $50,000 for individuals and $500,000 for corporations per offence.
Insurance angle: carriers increasingly request the annual S536-19 inspection report at policy renewal and after any claim. A non-compliant report or missing record can affect coverage or premium.
Other 2026 Fire Code changes worth knowing
O. Reg. 87/25 also amended several non-S536 items affecting apartment buildings. Highlights:
- Exit doors: all exit doors must meet locking standards or have simple releases allowing ready opening from inside. Electromagnetic devices require Chief Fire Official approval.
- Carbon monoxide alarms: buildings with forced-air fuel-burning appliances must place CO alarms outside sleeping areas, on every storey without sleeping areas, in appliance rooms, and in public corridors no more than 25 metres apart.
- Documentation and access: keys and specialized tools for fire alarm systems and fire protection equipment must be readily available to on-duty supervisory staff at all times.
- Central station monitoring: owners must obtain documentation confirming compliance with NFPA 71 or CAN/ULC-S561.
The CO alarm rules tie in closely with our existing Carbon Monoxide Alarm Rules 2026 guide.
