Fire Alarm Compliance for Building Owners and Property Managers (Ontario)
Ontario puts a small number of specific duties on the owner, and they are not the ones most sales conversations lead with. The Fire Code says the owner shall ensure the qualification requirements are met for the person doing the work, and gives the owner the right to demand that person's certificate. It requires records to be kept at the building — at least two years for a test or inspection record, and for the life of the system for the original verification report. It requires a current description of the fire alarm system to be kept in the building at an approved location. And it distinguishes two things that sound alike: a verification is a one-time Building Code duty on a new or modified system, while inspection and testing is an ongoing Fire Code duty on a system in service. If a quote does not tell you which of those two it is for, that is the first question to ask.
Who this page is for. A building owner, property manager or facility manager who has to keep a fire alarm system compliant and does not want to buy something the law does not require.
It is written to tell you what Ontario's codes actually oblige you to do. It does not recommend contractors, products or service intervals, and it has nothing to sell you. Every guide linked below quotes the code text and links the free source, so you can check any of it yourself.
Two codes, and they do different jobs
Ontario's requirements come from two separate regulations made under two separate statutes.
The Building Code — O. Reg. 163/24 — governs how a building is designed and constructed. It is where the requirement to install a fire alarm system to CAN/ULC-S524 lives (Article 3.2.4.5.(1)), and where the requirement to verify it to CAN/ULC-S537 lives (Article 3.2.4.5.(2)). Enforcement runs through the municipal building department and the permit.
The Fire Code — O. Reg. 213/07 — governs how the building is operated once it is in use. It is where inspection, testing, records and maintenance duties live. Enforcement runs through the Chief Fire Official.
As an owner you sit mostly on the Fire Code side, and you touch the Building Code side whenever construction, an extension or a modification happens. The distinction is explained in full in Building Code vs Fire Code: which one governs what.
The duties the Fire Code puts on you by name
Four of them are worth knowing in the words the regulation uses.
You must ensure the person doing the work is qualified. Fire Code Division C, Article 1.2.1.3.(2): "The owner shall ensure that the requirements of Article 1.2.1.2. are met." Article 1.2.1.2.(1) requires that person to have completed a program or course acceptable to the Fire Marshal. That applies to three tasks and only three: annual tests and inspections, testing and maintenance of components that interconnect with other fire protection and life safety systems, and repairs, replacements or alterations of components.
You are entitled to see the certificate. Article 1.2.1.2.(1)(b) requires the person to produce, at the request of the owner or the Chief Fire Official, a copy of a certificate or document attesting to completion of an accepted program. You do not need a reason to ask. Asking is the cheapest compliance step available to you.
If unqualified people did the work under supervision, you are owed something in writing. Article 1.2.1.2.(2) permits an unqualified person to perform repairs, replacements and alterations under supervision, with no more than two such people per supervisor and the supervision provided at the work site. Sentence (3) requires the supervisor to advise the owner in writing that the work was completed in accordance with the relevant provisions.
A current description of the system must be in the building. Fire Code Article 6.3.2.2.(3): the description of the fire alarm system required by CAN/ULC-S536 "shall be kept current and maintained in the building at an approved location."
The qualification rule and the supervision provision are set out with the full text in who can legally install, verify and test fire alarm systems in Ontario.
Verification and annual inspection are not the same purchase
This is the distinction that costs owners money, in both directions.
A verification is CAN/ULC-S537 work. It is a one-time event proving that a newly installed or modified system was built to its design and does what it is supposed to do, and it produces a Certificate of Verification. In Ontario it is required by the Building Code, at Article 3.2.4.5.(2). The Fire Code names S537 in exactly one article — 9.9.4.12.(2), which applies to hotel retrofits under Part 9 — so outside that there is no general Fire Code duty to verify.
An inspection and test is CAN/ULC-S536 work on a system already in service, required by Fire Code Article 6.3.2.2. Worth knowing precisely: that article states no frequency of its own. It delegates how often to the standard. The word "annual" enters through Division B Article 6.3.2.1 and Division C Article 1.2.1.1.
There is also a qualification asymmetry you should understand before you write a scope of work. The Fire Code names a qualification requirement for the person doing the annual inspection. It names none at all for the person performing a verification — verification is not on the Division C, Article 1.2.1.1 list. That does not mean anyone should do it; it means who is acceptable is a determination for your authority having jurisdiction, and the sensible move is to ask them before the work is booked rather than after.

Records: two years, and forever
Fire Code Article 1.1.2.2 sets two different retention rules, and the second is the one buildings fail.
Sentence (1): the original or a copy of any record required by the Code must be retained at the building for at least two years after being prepared, and so that at least the most recent and the immediately preceding record of a given test or inspection are retained.
Sentence (2): the initial verification or test reports for fire protection systems installed after 21 November 2007 must be retained throughout the life of the systems, regardless of whether the system was installed under the Fire Code or the Building Code.
So: annual inspection reports, two years and at least the last two. The original verification report, for as long as the system exists. That is why "we cannot find the verification report" is a genuine problem on a building from 2010 and a shrug on last year's annual — the original verification is the only record of how the system was proven when it was new, and the Code expects it to still be in the building decades later.
If you are taking over a building, ask for the original verification report before you take over, not after.
What changed on 1 January 2026
O. Reg. 87/25 amended the Ontario Fire Code effective 1 January 2026. It amended O. Reg. 213/07; it did not replace it — anything telling you Ontario has a brand new Fire Code is wrong about the document. The Fire Marshal's own communiqué also notes there are exceptions to that date which the published communiqué does not enumerate.
Four changes show up in the paperwork you receive:
- Report format is mandatory. With Ontario's move to the 2019 editions, the inspection report form is a prescribed format rather than a suggested template — tests and inspections should not be reworded or reordered.
- Battery testing means actual load testing, with recorded measurements.
- Deficiencies must be documented separately from general notes and recommendations.
- Attendance logs need names, dates and times.
Sourcing: these four points are reported consistently by Canadian trade sources, but they are not quoted from the regulation or from the standard — neither of which we have been able to verify them against. Treat them as reported rather than settled. The practical effect for an owner is that a report which looks like a contractor's own freeform template is a report worth questioning. Sources and detail in the Ontario Fire Code changes that took effect 1 January 2026.
What to ask a contractor
Not a script for negotiating price — a short list of questions the code itself gives you standing to ask. Any competent contractor will answer all of them without hesitation.
- Is this quote for a verification or for inspection and testing? If the answer mixes the words, ask again. They are different standards under different codes.
- Which standard and which edition are you working to? Ontario designates specific editions in code tables — the newest published standard is usually not the one in force.
- Who will be on site, and can they produce their certificate? Article 1.2.1.2.(1)(b) entitles you to ask.
- Will anyone be working under supervision? If so, the two-per-supervisor and on-site limits apply, and you are owed written confirmation when the work is done.
- Will I receive the report in the prescribed format? Since 1 January 2026 that is not a stylistic preference.
- Will deficiencies be listed separately from recommendations? A deficiency is a code matter. A recommendation is a suggestion. Conflating them is how owners end up paying for work nothing requires.
- Where is the original verification report for this building, and where is the current system description kept? Both are supposed to be at the building.
On the last point especially: if a proposal recommends replacing a system, ask which code provision requires the replacement. Neither addressable nor conventional architecture is required by Canadian code — those are industry terms, not defined terms in either Ontario code. See addressable vs conventional fire alarm systems.
Smoke alarms are a separate duty
The disc in a dwelling unit is often not part of the fire alarm system at all, and the law treats the two differently. A smoke alarm is self-contained. A smoke detector is an initiating device on the system.
Annual testing of smoke alarms is a landlord duty under Fire Code Article 6.3.3.8, performed by activating the test feature — no Fire-Marshal-accepted program is required for it. Testing a smoke detector on a fire alarm system is not that, and does carry the qualification requirement. Interconnected smoke alarm systems have their own rules again, including a qualification requirement under a different subsection of Division C.

What this page cannot tell you
It cannot tell you what is inside CAN/ULC-S536 or S537 — the intervals, the procedures, the pass criteria, the report contents. Those are paid publications and there is no legitimate free copy of any of them, which is also why the inspection frequency question does not have a free public answer: Fire Code Article 6.3.2.2 delegates it to the standard.
It cannot tell you what your authority having jurisdiction will accept, particularly on who may perform a verification, where Ontario names nobody.
And it does not recommend contractors. Nothing on this site is a referral, and nobody pays to be listed here.
Not affiliated with, endorsed by or accredited by the CFAA, ECAO, ULC Standards, UL Standards & Engagement Inc., the Office of the Fire Marshal, any authority having jurisdiction, or any manufacturer.

Frequently asked questions
How often must a fire alarm system be inspected in Ontario?
Fire Code Article 6.3.2.2 requires inspection and testing in conformance with CAN/ULC-S536 and states no frequency of its own — it delegates that to the standard, which is a paid publication. The word annual reaches the Code elsewhere: Division B Article 6.3.2.1 refers to the annual tests or annual inspections required by the Subsection, and Division C Article 1.2.1.1 applies to a person who performs annual tests or inspections required under 6.3.2.2. So annual is the right general expectation, but the detailed schedule lives inside the standard rather than in any free public text.
How long do I have to keep fire alarm records?
Fire Code Article 1.1.2.2.(1) requires records to be retained at the building for at least two years after being prepared, and so that at least the most recent and the immediately preceding record of a given test or inspection are kept. Sentence (2) goes much further for one document: the initial verification or test reports for fire protection systems installed after 21 November 2007 must be retained throughout the life of the system, regardless of whether it was installed under the Fire Code or the Building Code.
Am I responsible for checking my contractor's qualifications?
Yes, in a specific sense. Fire Code Division C, Article 1.2.1.3.(2) states that the owner shall ensure the requirements of Article 1.2.1.2 are met, and Article 1.2.1.2.(1)(b) requires the person doing the work to produce a certificate or document attesting to completion of a Fire-Marshal-accepted program at the request of the owner or the Chief Fire Official. The requirement attaches to three tasks: annual tests and inspections, interconnection testing, and repairs, replacements or alterations.
My contractor says my system needs to be replaced because it is not addressable. Is that a code requirement?
Addressable and conventional are industry terms, not defined terms in Ontario's Building Code or Fire Code, and neither architecture is required by Canadian code. What the codes require is installation in conformance with CAN/ULC-S524, separate zone indication at the annunciator, inspection and testing to CAN/ULC-S536 and repairs to S524 — all of which either architecture can satisfy. If a replacement is being proposed, the reasonable question is which code provision or which documented deficiency requires it.
What is the difference between a deficiency and a recommendation on my inspection report?
A deficiency is a failure against the requirement; a recommendation is a suggestion. Canadian trade sources report consistently that, alongside the Ontario Fire Code changes in force on 1 January 2026, deficiencies must be documented separately from general notes and the inspection report form is a prescribed format rather than a suggested template, with tests and inspections not to be reworded or reordered. That is reported rather than settled — it is not quoted from the regulation or from the standard, neither of which we have been able to verify it against. If the two are blended together in the document you receive, that is still worth raising before you approve remedial work.
Do I need to keep the original verification report if the building changed hands?
The duty attaches to the building rather than to the person who commissioned the work: Fire Code Article 1.1.2.2 requires records to be retained at the building to which they relate, and Sentence (2) keeps the initial verification report there for the life of the system. Practically, that makes the original verification report something to ask for during a purchase or a management transition, because reconstructing it later is not possible — a verification is a record of how the system was proven when it was new.

Who Can Legally Install, Verify and Test Fire Alarm Systems in Ontario?
Ontario law does name who may work on fire alarm systems — and most articles on this subject get it wrong. Under Division C, Subsection 1.2.1 of the Ontario Fire Code, anyone performing annual tests or inspections, or repairing, replacing or altering fire alarm system components, must have completed a program or course acceptable to the Fire Marshal. The regulation names no program itself; the Fire Marshal's published list currently holds two — the CFAA Fire Alarm Technician Training Program and the ECAO Certi-Fire program. Separately, the electrical installation work itself requires a 309A certificate, because electrician is a compulsory trade.
CAN/ULC-S524, S537, S536 and S1001: What Each Standard Actually Covers
Canada splits fire alarm work across four separate standards where the American system uses one. S524 governs installation. S537 governs verification — a one-time event that proves the install matches the design. S536 governs periodic inspection and testing, forever after. S1001 governs integrated testing, where the fire alarm has to talk to other building systems. Confusing verification with inspection is the most expensive mistake in Canadian fire alarm work, and it happens constantly.
