Fire Protection for Ontario Restaurants: What Every Owner and Operator Must Know in 2026

Running a restaurant in Ontario means managing a business that operates under one of the most demanding fire safety compliance frameworks in the province. Commercial kitchens generate concentrated heat, open flames, and grease-laden vapours at volumes and frequencies no other occupancy type matches. A kitchen fire can engulf a hood system in seconds. A suppression system that has not been properly maintained may fail at exactly the moment it is needed most.

Ontario's fire protection requirements for restaurants reflect this reality. Under the Ontario Fire Code, O. Reg. 213/07, restaurant operators are subject to a specific and non-negotiable compliance regime that covers kitchen hood suppression systems, fire alarm systems, portable fire extinguishers, emergency lighting, exit signage, and fire safety plans. The 2026 Ontario Fire Code amendments — brought into effect under O. Reg. 87/25 on January 1, 2026 — have added new obligations around fire alarm inspections, carbon monoxide detection, and documentation standards that every restaurant operator and property owner must understand.

This guide covers everything Ontario restaurant owners, operators, and property managers need to know about fire protection compliance in 2026.

Why Restaurants Face Elevated Fire Risk

Cooking is the leading cause of fires in commercial occupancies. Grease buildup in kitchen exhaust systems — hoods, ducts, and fans — is the primary ignition pathway. A single high-volume service can deposit significant grease accumulation in a hood plenum. Over weeks and months, this buildup becomes a serious fire load. When it ignites, it can extend rapidly through an exhaust duct to the roof, compromising the entire building structure.

Ontario restaurants also operate with concentrated gas systems, high-BTU cooking equipment, large numbers of staff moving through tight spaces, and dining rooms full of members of the public. The combination of fire risk, staff density, and public occupancy is why the Ontario Fire Code and NFPA 96 — the Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations — apply such detailed requirements to this occupancy type.

Non-compliance is not an abstract risk. The Ontario Fire Marshal's Office and municipal fire prevention offices actively inspect restaurants, and the consequences of non-compliance range from orders to comply to prosecution under the Fire Protection and Prevention Act, 1997, with fines of up to $50,000 for individuals and $100,000 for corporations per offence. A serious fire in a non-compliant restaurant can also expose operators and building owners to civil liability.

Kitchen Hood Suppression Systems: The Most Critical Compliance Obligation

For most Ontario restaurants, the kitchen hood suppression system is the most important fire protection component in the building. It is also the one most commonly found in deficiency during inspections.

What the Law Requires

Under the Ontario Fire Code and NFPA 96, commercial kitchen hood suppression systems must be inspected and serviced by a qualified technician at least twice per year — every six months. The semi-annual inspection interval applies regardless of cooking volume or menu type. High-volume operations, solid fuel cooking, and high-grease menus may require more frequent servicing under NFPA 96.

Each inspection must verify that the suppression agent tanks are fully charged, that all nozzles are in place and unobstructed, that fusible links or thermal detectors are intact and correctly positioned, that the system activates the automatic gas shutoff on discharge, that the manual pull station is accessible and operational, and that the interconnection to the fire alarm system functions as required.

Documentation

Every inspection must be documented using the inspection report form specified by the suppression system manufacturer. The report must identify any deficiencies found and any corrective action taken. Inspection records must be retained and available for review by the Authority Having Jurisdiction (AHJ) — your local fire department — upon request.

Grease Cleaning: A Separate but Related Obligation

Kitchen hood suppression inspections are separate from hood cleaning. Grease accumulation in hoods, ducts, and exhaust fans must be managed through regular cleaning by qualified personnel, with frequency determined by cooking volume and menu type. NFPA 96 specifies cleaning intervals ranging from monthly for solid-fuel cooking to annually for low-volume operations. Both suppression inspection and grease cleaning records must be maintained.

Fire Alarm Systems

Ontario restaurants are typically classified as Group A2 occupancies under the Ontario Building Code, which triggers specific fire alarm requirements. The applicable detection, alarm, and notification standards depend on building size, occupancy load, and the presence of sprinkler systems.

2026 Changes to Fire Alarm Inspection Standards

Effective January 1, 2026, Ontario has adopted the updated CAN/ULC-S536:2019 standard for annual fire alarm inspections. This is the most significant change to fire alarm inspection requirements in Ontario in two decades. The new standard is substantially more detailed than its predecessor, expanding from 44 pages to 73 pages and adding over 100 new inspection items.

For restaurant operators, the practical impact is that annual fire alarm inspections will be more thorough and more time-consuming than in previous years. Inspection reports will be more detailed. Technicians must now use the standardized report forms specified in the CAN/ULC-S536:2019 standard. Modified or abbreviated forms that some contractors used under the previous standard are no longer acceptable.

If your restaurant's fire alarm has not been inspected since the January 1, 2026 effective date, your next inspection must comply with the new standard.

Kitchen Suppression to Fire Alarm Interconnection

Under both NFPA 96 and the Ontario Fire Code, the kitchen hood suppression system must be interconnected with the building's fire alarm system such that suppression system activation triggers alarm notification throughout the building. This interconnection must be tested as part of both the fire alarm annual inspection and the semi-annual suppression inspection.

Fire Extinguishers

Every restaurant in Ontario must maintain adequate portable fire extinguisher coverage throughout the premises. The Ontario Fire Code requires annual inspection and servicing of all portable extinguishers by a licensed technician.

In commercial kitchens, Class K extinguishers are required. Class K extinguishers contain wet chemical agents specifically formulated to suppress grease fires and are the correct tool for kitchen fires involving cooking oils and fats. Class K extinguishers must be installed near the cooking equipment they protect and within the travel distance specified by the Ontario Fire Code.

In addition to annual service, restaurant operators are responsible for conducting monthly visual checks of all extinguishers to confirm that they are in their designated location, that the pressure gauge reads in the proper operating range, that the pull pin and tamper seal are intact, and that the extinguisher shows no visible damage. These monthly checks must be documented.

Emergency Lighting and Exit Signs

Ontario restaurants are subject to the emergency lighting and exit sign requirements of the Ontario Fire Code, which mandate that all required exit and egress routes remain lit when normal power is interrupted. Emergency lighting units must have backup battery systems sufficient to maintain illumination for at least 30 minutes following a power failure.

Testing requirements include:

• A 30-second functional test every month, confirming that the unit activates and illuminates when power is interrupted
• A full 30-minute duration test annually, confirming that the backup battery sustains the required illumination for the full required period

All tests must be documented. Deficient units must be repaired or replaced promptly.

Exit signs must be continuously illuminated during all occupied hours and must have backup power to remain lit during power failures. Exit signs that are unlit, obscured, or missing represent one of the most commonly cited deficiencies during restaurant fire inspections.

Carbon Monoxide Detection

The 2026 Ontario Fire Code amendments expanded the carbon monoxide alarm requirements for commercial occupancies. Restaurants that operate gas-fired appliances — commercial ranges, ovens, fryers, broilers, and warming equipment — must have CO alarms installed adjacent to all sleeping areas if the building contains sleeping accommodations, and in other areas as determined by the local AHJ.

For restaurants in mixed-use buildings that include residential units, or for operators who have overnight staff accommodations on the premises, the 2026 CO alarm requirements require particular attention. Your local fire prevention office is the appropriate authority for confirming the specific requirements that apply to your building configuration.

Fire Safety Plans

Under the Ontario Fire Code, most restaurants are required to have a Fire Safety Plan in place. The Fire Safety Plan is a building-specific document that identifies fire protection systems, emergency procedures, staff responsibilities, evacuation routes, and fire department contact information.

The Fire Safety Plan must be reviewed and updated whenever there is a material change to the building, its occupancy, or its fire protection systems. It must be kept on the premises and made available to the fire department upon request. Restaurant renovations, changes to cooking equipment, or changes to the building's fire alarm or suppression systems all trigger a review obligation.

Occupancy Load and Signage

Assembly occupancies — which include restaurants, bars, and food service establishments — must post their maximum occupancy load prominently at the main entrance to the dining area. Exceeding the posted occupancy is a direct Ontario Fire Code violation and one of the most common deficiencies cited during municipal inspections of licensed premises.

Occupancy loads are established by the Ontario Building Code based on floor area and occupancy type and are confirmed by the local building inspection authority. If your restaurant has undergone renovations, it is worth confirming that your posted occupancy load reflects the current approved configuration.

What Happens During a Restaurant Fire Inspection

Municipal fire prevention officers conduct inspections of restaurants on a routine basis and in response to complaints. During a restaurant fire inspection, you can expect the officer to verify the following:

Kitchen Suppression System

The officer will review your semi-annual inspection records and confirm that the system has been serviced within the required six-month interval. They will visually inspect the suppression nozzles, fusible links, pull station, and agent tanks. Missing, obstructed, or damaged components will result in an order to comply.

Fire Alarm System

The officer will review your annual fire alarm inspection records and confirm that they comply with the current standard. Post-January 2026 inspections must use CAN/ULC-S536:2019 compliant report forms.

Fire Extinguishers

The officer will confirm annual service tags and monthly inspection records for all extinguishers, including Class K units in the kitchen.

Emergency Lighting and Exit Signs

The officer will visually inspect all emergency lighting units and exit signs. Non-functional or missing units will result in an order to comply.

Fire Safety Plan

The officer will request to see your current Fire Safety Plan and may review it for currency and completeness.

Occupancy Load Signage

The officer will confirm that maximum occupancy load is posted at the entrance to the dining area.

Common Deficiencies Found in Ontario Restaurant Inspections

The following deficiencies appear repeatedly in Ontario restaurant fire inspections:

• Kitchen suppression system past its inspection due date. The six-month interval passes quickly in a busy restaurant environment. Many operators lose track of inspection dates, particularly after staff changes.
• Grease buildup in the hood system with no current cleaning record. Operators who self-clean without maintaining documentation have no way to demonstrate compliance.
• Class K extinguisher missing or not positioned adjacent to cooking equipment. A Class ABC extinguisher in the kitchen area does not satisfy the Class K requirement.
• Emergency lighting units failing the monthly or annual test. Battery degradation is common in units that have not been tested or maintained consistently.
• Exit signs unlit or obscured. Signage installed at renovation and then not maintained is a consistent problem.
• Fire alarm inspection records reflecting the old standard. Post-2026 inspections must use the CAN/ULC-S536:2019 compliant forms.
• No current Fire Safety Plan. Plans prepared years ago that have not been updated to reflect current equipment or personnel.

Choosing a Fire Protection Contractor for Your Restaurant

Ontario restaurants should work with a fire protection contractor who holds the qualifications required to service all systems in the building. This includes TSSA authorization for sprinkler systems, manufacturer certification for the specific kitchen suppression system brand installed in your kitchen, and CFAA certification for fire alarm inspection and servicing.

When selecting a contractor, confirm that they:

• Hold all required TSSA authorizations for your province
• Are certified to service your specific kitchen suppression system brand (Ansul, Amerex, Kidde, Pyro-Chem, or other)
• Use CAN/ULC-S536:2019 compliant report forms for fire alarm inspections
• Maintain technician attendance logs and provide signed inspection certificates
• Clearly identify deficiencies versus recommendations in their reports

A contractor who cannot clearly demonstrate these qualifications may leave your restaurant in a compliance position that does not hold up to scrutiny from your local AHJ or your insurer.

A Note on Insurance

Commercial property and general liability insurers increasingly require current inspection documentation as a condition of coverage. A restaurant that cannot produce current semi-annual suppression inspection records, annual fire alarm inspection records, and annual extinguisher service records may find that its insurer denies a claim following a fire — or that coverage is declined at renewal.

Fire protection documentation is not just a regulatory requirement. It is a condition of the insurance coverage your business depends on.
