NFPA 96 Fire Code Guide for Vaughan Kitchens
NFPA 96 is the standard published by the National Fire Protection Association for ventilation control and fire protection of commercial cooking operations. It governs the whole grease path in a commercial kitchen: hood, filters, plenum, duct, rooftop fan and the suppression over the appliances. It publishes how often that path is inspected, the grease depth at which a surface must be cleaned, and what record is kept. In Vaughan the standard reaches a kitchen through the Ontario Fire Code, which references NFPA 96, and Vaughan Fire and Rescue Service enforces the Fire Code. This guide references the published standard. Vaughan Hood Cleaning Pros is not affiliated with NFPA.

What NFPA 96 is, and what it covers
NFPA 96 is a technical standard, not a law. Its cleaning chapter rests on three ideas.
Grease is fuel. Grease inside the exhaust path is treated as a fire load, so the standard sets a measurable depth at which a surface must be cleaned. That depth is 0.078 inches, and it applies to every surface on the path: the plenum wall behind the filters, the inside of the duct, and the inside of the fan housing. The reading goes on the record.
Inspection sets the schedule. The standard publishes how often a system is inspected for grease build-up, by the type and volume of cooking. Cleaning follows when the inspection finds deposit at or over the limit.
Records are part of compliance. Dated records of inspection and cleaning that state what was done and by whom.
Monthly vs quarterly vs semi-annual vs annual: NFPA 96 inspection frequency by cooking volume
NFPA 96 publishes four inspection intervals, set by the type and volume of cooking rather than the size of the kitchen.
| Cooking volume vs published interval | Type of cooking operation named in NFPA 96 | What that looks like in Vaughan |
|---|---|---|
| Monthly | Solid-fuel cooking | A wood-fired pizza oven in a Woodbridge or Kleinburg trattoria, or a charcoal grill. |
| Quarterly | High-volume cooking, including 24-hour operation, charbroiling and wok cooking | A charbroiler on a franchise line near Vaughan Mills, or a wok station on Highway 7. |
| Semi-annually | Moderate-volume cooking | A single-shift restaurant in Maple, or a workplace cafeteria in Concord that serves lunch five days a week. |
| Annually | Low-volume cooking, including churches, day camps and seasonal businesses | A faith kitchen used on weekends, or a seasonal snack kitchen. |

How the Ontario Fire Code references NFPA 96 in Vaughan
The Ontario Fire Code is the provincial fire safety regulation for existing buildings, and it references NFPA 96 as the standard that commercial cooking exhaust systems are inspected and cleaned against.
The Fire Code is the law. Its requirements for commercial cooking equipment point to NFPA 96 for the technical detail: what is inspected, how often, to what depth, and what is recorded. A fire inspector in Vaughan carries the Fire Code, and the Fire Code carries NFPA 96 inside it.
What Vaughan Fire and Rescue Service looks for on an inspection
Vaughan Fire and Rescue Service is the one fire service for every community in the City of Vaughan. It enforces the Ontario Fire Code from ten fire stations across Woodbridge, Maple, Concord and Kleinburg, with headquarters at the Joint Operations Centre on Rutherford Road in Concord.
A fire inspection tends to follow the same order. The inspector asks for the most recent cleaning record and reads what it names. A record that lists the canopy and nothing else invites the question of whether the duct was opened. The inspector then looks behind the filters at the plenum, checks that duct access panels can be reached, and confirms the rooftop fan can be opened.
Fire services enforce. They do not issue cleaning certificates and they do not endorse contractors. The certificate on file is the operator's evidence, read as evidence rather than proof.
Top-rated NFPA 96 certificate in Vaughan: what to look for
A hood cleaning certificate asserts that named sections of one specific system were cleaned on one specific date by one specific contractor with reference to the published NFPA 96 standard. It does not assert that the kitchen passed a fire inspection or that NFPA has approved the contractor.
What it asserts. The sections cleaned, by name: canopy, filters, plenum, horizontal run, riser, fan. The date. The grease depth found. A signature. Vaughan Hood Cleaning Pros issues a signed health and safety certificate on that basis, with before-and-after photographs of every cleaned surface, stating that the work references the published NFPA 96 standard and that the business is not affiliated with NFPA.
What it does not assert. It is not a fire inspection. It does not cover any section it does not name, so a certificate that says only "hood" covers only the hood. And no certificate makes a contractor certified by NFPA, because NFPA does not certify companies. The scopes behind the sections are on the exhaust hood cleaning, kitchen exhaust hood cleaning and exhaust fan repair pages.
Is there such a thing as a certified hood cleaning company in Vaughan?
A certified hood cleaning company is not a credential that exists in Ontario. NFPA writes standards and does not certify contractors, the Ontario Fire Code does not license hood cleaners, and Vaughan Fire and Rescue Service does not endorse them.
The phrase is searched hundreds of times a year, and no body issues it. The proof that does exist is a signed certificate that names the sections cleaned and references the published standard, before-and-after photographs, and proof of WSIB coverage and liability insurance before work starts. A contractor who answers with "NFPA certified" has described a credential NFPA does not issue.

NFPA 96 in Vaughan: frequently asked questions
Does NFPA 96 apply to a faith or community kitchen that cooks a few times a month?
NFPA 96 covers every commercial cooking operation that produces grease-laden vapour, however often it runs. Churches, day camps and seasonal businesses are named in the published table with an annual interval.
What does the Ontario Fire Code actually say about NFPA 96?
The Ontario Fire Code references NFPA 96 as the standard for the inspection and cleaning of commercial cooking exhaust systems. The Fire Code is the regulation and NFPA 96 is the technical document it points to.
Why does a wood-fired oven put a Woodbridge trattoria on a monthly interval?
A wood-fired oven is a solid-fuel appliance under NFPA 96, and solid-fuel cooking carries the shortest published interval: monthly. The appliance sets the interval, not the number of covers.
Is a hood cleaning certificate the same as passing a fire inspection?
A hood cleaning certificate is the contractor's record of what was cleaned. A fire inspection is the fire service's check of the whole kitchen, which reads the certificate as one piece of evidence among several.
Does York Region Public Health inspect the exhaust system?
York Region Public Health inspects food premises for food safety and publishes the results through YorkSafe. The exhaust path is a fire matter under the Ontario Fire Code, so it belongs to Vaughan Fire and Rescue Service.
