The Ontario Fire Code Explained
What the OFC is, how it differs from the Building Code, and what it actually requires of building owners, property managers, and the people who maintain fire protection systems.
What the Ontario Fire Code is
The Ontario Fire Code (OFC) is a regulation made under Ontario's Fire Protection and Prevention Act. While the Ontario Building Code governs how new buildings get designed and constructed, the Fire Code governs what happens afterward — for the entire life of the building. It sets minimum fire safety requirements for buildings that are already standing, already occupied, and already in day-to-day operation.
That scope is broader than many people expect. The OFC addresses how fire protection equipment must be maintained and tested, how combustible materials must be handled and stored, how exits must be kept usable, how fire safety planning must be documented, and — in certain cases — how older buildings must be physically upgraded to a baseline level of safety even though they were legal when built.
If you own, manage, inspect, or service a building in Ontario, the Fire Code applies to you every single day, not just on the day the building was approved for occupancy.
OBC vs. OFC: construction vs. operation
The single most common point of confusion in Ontario fire safety is the relationship between the Building Code and the Fire Code. The cleanest way to keep them straight:
- The Ontario Building Code (OBC) answers design and construction questions: does this building need a fire alarm system, sprinklers, rated separations, a second exit? It applies when a building is constructed, renovated, or undergoes a change of use.
- The Ontario Fire Code (OFC) answers operational questions: is the fire alarm being tested, are the extinguishers serviced, is the fire safety plan current, are the exit doors actually openable? It applies continuously, to existing buildings, regardless of when they were built.
A useful mental model: the Building Code puts the safety systems into the building; the Fire Code keeps them working. The two codes are designed to hand off to each other — the day a new building is occupied, the Fire Code's maintenance and operational obligations take over.
Key areas the OFC covers
Fire safety plans
A fire safety plan is a building-specific document that describes how occupants and staff will respond to a fire: emergency procedures, the appointment and training of supervisory staff, evacuation provisions for people who need assistance, schematic diagrams, and the maintenance schedule for the building's fire protection equipment. The Fire Code requires fire safety plans for a wide range of buildings — including those with fire alarm systems, assembly occupancies, care facilities, high buildings, and many others.
The plan must be approved by the Chief Fire Official, kept on the premises, and reviewed at intervals to make sure it still reflects how the building is actually used and staffed. A fire safety plan written ten years ago for a building that has since changed tenants, renovated floors, or replaced its alarm system is a common inspection finding.
Maintenance, inspection, and testing of fire protection systems
This is the heart of the Fire Code for technicians and service companies. The OFC requires that installed fire protection systems — fire alarms, sprinklers, standpipes, emergency lighting, fire pumps, special suppression systems — be inspected, tested, and maintained so they perform as intended. The Code sets the obligation and the frequency; it generally points to recognized standards for the detailed procedures. A fire alarm system, for example, must receive specified daily, monthly, and annual attention, with records kept.
Retrofit requirements
Most fire safety rules accept that older buildings were built to older codes. Ontario's retrofit provisions are the exception: for certain occupancy types — including residential buildings, care occupancies, and assembly buildings — the Fire Code requires existing buildings to be upgraded to a defined minimum level of life safety. Retrofit can mean adding smoke alarms or alarm systems, improving fire separations, or upgrading exits. For owners of older residential stock, retrofit compliance is frequently the most significant Fire Code obligation they face.
High buildings
Buildings that fall into the high building category carry extra operational requirements: more detailed fire safety planning, voice communication considerations, smoke control system maintenance, and additional supervisory staff duties. If you manage a high-rise, expect both your fire safety plan and your testing program to be more involved than for a low-rise property.
Portable fire extinguishers
The Fire Code addresses where extinguishers are required, how they must be selected for the hazard, and how often they must be inspected and serviced. Monthly checks and annual maintenance are the rhythm most building staff will recognize, with periodic hydrostatic testing for the cylinders themselves.
Owner responsibility
The Fire Code places responsibility for compliance squarely on the building owner. Owners can — and almost always do — delegate the work: a service company performs the annual fire alarm test, a contractor services the extinguishers, a property manager keeps the fire safety plan current. But delegation does not transfer the legal obligation. If the annual test was missed, the order is issued to the owner. For property managers, this means your role is to operate a system of contracts, schedules, and records that demonstrably keeps the building compliant on the owner's behalf.
The S536 connection
The Fire Code and CAN/ULC-S536 work as a pair. The OFC creates the legal requirement that a fire alarm system be inspected and tested at prescribed intervals. CAN/ULC-S536 — the standard for the inspection and testing of fire alarm systems — defines how that work is actually performed: what gets checked daily, monthly, and annually, what test methods apply to each device type, and how results are documented. A technician performing an "annual" on a fire alarm system in Ontario is simultaneously satisfying a Fire Code obligation and following S536 procedures. Neither document works alone: the OFC without S536 has no test methodology; S536 without the OFC has no legal force.
Enforcement
The Fire Code is enforced primarily by municipal fire departments through their fire prevention divisions. Inspectors may enter and inspect buildings, review records, and issue inspection orders requiring deficiencies to be corrected within a set time. Orders can be appealed, but ignoring them is a serious matter — the Fire Protection and Prevention Act provides for prosecution, and penalties for non-compliance can be substantial for both individuals and corporations. In cases of immediate danger, fire officials have stronger powers, up to closing a building.
In practice, most enforcement is cooperative: an inspector identifies deficiencies, the owner corrects them, records are updated. The owners who run into trouble are usually those with no records at all — because without documentation, there is no way to demonstrate that required testing ever happened.
Common questions
My building was built in the 1970s. Does the Fire Code still apply?
Yes. The Fire Code applies to existing buildings regardless of age. Day-to-day operational requirements — testing, maintenance, fire safety planning, housekeeping — apply to every building, and the retrofit provisions may additionally require physical upgrades depending on the occupancy type.
Who is allowed to do the annual fire alarm test?
The Fire Code requires the testing to be done; in practice it is performed by qualified fire alarm technicians following CAN/ULC-S536. Most owners hire a fire protection service company. Whoever performs it, complete records must be produced and retained, because those records are what an inspector will ask to see.
How long do I need to keep testing records?
The Fire Code requires records of tests and corrective measures to be retained for a prescribed period — long enough that an inspector can review the recent history of the system. As a practical matter, keep them longer: records are also your best evidence of due diligence if anything ever goes wrong.
Do I need a fire safety plan for a small commercial building?
It depends on the occupancy and the systems installed. Many smaller buildings are captured because they contain a fire alarm system or an assembly occupancy. If you are unsure, ask your local fire prevention office — they approve the plans and can tell you whether one is required for your building.
What happens if I receive an inspection order I disagree with?
There is a formal review and appeal process under the Fire Protection and Prevention Act. Start by discussing the order with the issuing fire department — many disputes come down to information the inspector did not have. If that fails, the appeal routes exist, but they run on deadlines, so act quickly.
