2026 Ontario Fire Code Bedroom Safety Guide

10 min read

If you own a home in Brantford, rent out a unit, or are planning a bedroom renovation in 2026, the Ontario Fire Code has new rules that affect you. Ontario Regulation 87/25 came into effect on January 1, 2026, and it touches everything from where you put your carbon monoxide alarms to how secondary suites are wired for smoke detection.

We sell mattresses, not fire alarms. But here is the thing: bedroom safety does not stop at the mattress. When customers come into our showroom on West Street asking about setting up a new bedroom in their basement suite, or outfitting a rental unit, or renovating after their kids have moved out, the conversation naturally turns to what the room itself needs to be safe and code-compliant. We hear these questions enough that we wanted to put everything in one place.

This guide covers the 2026 Ontario Fire Code changes that directly affect bedrooms, sleeping areas, and residential units. We will connect the dots to mattress safety where it applies, because the materials in your mattress and the fire protection around your bedroom are part of the same safety picture.

What Changed on January 1, 2026

Ontario Regulation 87/25 was approved by the Solicitor General of Ontario on June 2, 2025. It updates the Ontario Fire Code (O. Reg. 213/07) to harmonize with the 2020 National Fire Code of Canada, while adding several Ontario-specific requirements. The changes came into force on January 1, 2026, with a few narrow exceptions.

The big-picture changes that affect bedrooms and residential living spaces include:

• CO alarm placement expansion to every storey, not just near sleeping areas
• Wireless interconnected smoke alarms now permitted for houses with secondary suites
• Administrative Monetary Penalties (AMPs) as a new enforcement tool for municipalities
• Mass timber protective covering maintenance requirements for newer buildings
• Stronger requirements for boarding, lodging, and rooming houses including reduced flame-spread ratings for interior wall and ceiling finishes
• Updated fire alarm inspection standards (ULC-S536 and ULC-S537, 2019 editions)

CO Alarms on Every Storey: What It Means for Bedrooms

This is the change that affects the most Ontario households. Previously, the fire code required CO alarms adjacent to sleeping areas in homes with fuel-burning appliances, fireplaces, or attached garages. That meant you might have had one alarm in the upstairs hallway near your bedrooms and called it compliant.

As of January 1, 2026, CO alarms are required on every storey of your home, including storeys that do not have a sleeping area. That means your basement (even if nobody sleeps there), your main floor, and your upper floors all need CO alarms. If your home has a fuel-burning furnace in the basement and bedrooms on the second floor, a single alarm upstairs is no longer enough. You need one on each level.

Which Homes Need to Comply

The requirement applies to all existing residential occupancies that have any of the following:

• A fuel-burning appliance (furnace, water heater, stove, or dryer that uses natural gas, propane, oil, or wood)
• A fireplace (including gas inserts)
• An attached garage
• Air for heating that comes from a fuel-burning appliance not fully contained within the home

If you have an all-electric home with no attached garage and no fireplace, CO alarms are not required by the fire code (though many safety experts still recommend them). For everyone else in Brantford, and that includes the vast majority of homes here given our climate and the prevalence of gas furnaces, this is a mandatory change.

Placement Details for Bedrooms

CO alarms must be installed adjacent to each sleeping area. "Adjacent" in code language means within the hallway or space immediately outside the bedroom door, or inside the bedroom itself. The new every-storey requirement is on top of the sleeping-area requirement, not a replacement for it. So if your bedrooms are on the second floor and your living room is on the main floor, you need alarms near the bedrooms upstairs and a separate alarm on the main floor.

Wireless Interconnected Smoke Alarms for Secondary Suites

The 2024 Ontario Building Code introduced a practical change for homeowners adding secondary suites (basement apartments, in-law suites, and similar): smoke alarms in the house can now be wirelessly interconnected instead of requiring hardwired connections between units.

The intent is straightforward. When you create a secondary suite in an existing home, running new wiring between the suite and the main dwelling to connect smoke alarms can be expensive and physically difficult. Wireless interconnection lets all smoke alarms in the building communicate with each other through radio signals, so if one alarm goes off in the basement suite, every alarm in the house sounds.

Requirements and Standards

Wireless interconnected smoke alarms in Ontario must comply with CAN/ULC-S531-2019, which specifies requirements for integral transceivers used in non-supervised wireless interconnected alarms. The key points:

• All smoke alarms within the house (main dwelling and secondary suite) must be interconnected, either wirelessly or by hardwiring
• The wireless option is specifically intended for houses with secondary suites where running new wiring between suites is impractical
• Battery-powered wireless interconnected alarms are permitted, though many professionals recommend units with 10-year sealed lithium batteries for reliability

Cost Comparison: Hardwired vs. Wireless

For Brantford landlords and homeowners considering a secondary suite, the cost difference matters. Here is a rough comparison:

If you are converting a Brantford rental property and adding a secondary suite, the wireless option can save you significant renovation cost while still meeting the building code. Talk to your local building department to confirm requirements for your specific project.

Visual Signaling Smoke Alarms for Bedrooms

Ontario has required visual signaling (strobe) smoke alarms in bedrooms for the protection of Deaf and hard-of-hearing individuals since 2015. The 2026 fire code does not change this requirement, but it is worth covering here because many landlords and homeowners are not aware of it when setting up bedrooms.

What the Code Requires

Visual signaling components installed in sleeping rooms must have a minimum luminous intensity of 175 candelas (cd). That is significantly brighter than a typical household light, because the strobe needs to be intense enough to wake a sleeping person through closed eyelids. Standard smoke alarms with a small LED indicator light do not meet this requirement.

For bedrooms specifically, the recommended setup for residents who are Deaf or hard of hearing includes:

• ULC-listed visual alarm (strobe) rated at 175 cd minimum
• Bed-shaker accessory that vibrates the mattress or pillow when the alarm triggers
• Integration with the building's interconnected alarm system so that any alarm in the unit triggers the visual and tactile alerts in the bedroom

Fire Separation Walls Between Units

If you are adding a secondary suite to your Brantford home or dividing an existing building into separate units, fire separation between the units is one of the most critical (and expensive) requirements. The Ontario Building Code specifies fire-resistance ratings for the walls, floors, and ceilings that separate dwelling units.

The 45-Minute Standard

Under the Ontario Building Code (Part 9, residential buildings), suites in residential occupancies generally require a 45-minute fire-resistance rating for the separating assembly. In practice, this typically means:

• 5/8-inch Type X fire-rated drywall on each side of the wall assembly
• Fire-stop materials at all penetrations (electrical boxes, pipes, ducts, and any other openings through the assembly)
• Insulation: Rockwool or mineral wool insulation (such as Roxul Safe'n'Sound) in the wall cavity, which provides both fire resistance and sound control

The "45-minute" rating means the assembly is tested to maintain structural integrity and prevent flame passage for at least 45 minutes in standardized fire conditions. A single layer of 5/8-inch Type X drywall on each side of a wood-framed wall, properly installed with sealed penetrations, typically achieves this rating.

Why 5/8-Inch Type X Drywall Matters

Type X drywall contains glass fibres mixed into the gypsum core, which hold the panel together longer during a fire. Standard 1/2-inch drywall provides roughly 15 minutes of fire resistance. Type X 5/8-inch drywall provides approximately 60 minutes per layer. That single extra 1/8-inch of thickness, combined with the glass fibre reinforcement, nearly quadruples the protection time.

Sound Transmission Bonus

Here is where fire separation connects to bedroom design and sleep quality. A properly built fire separation wall with Type X drywall and mineral wool insulation also achieves an STC (Sound Transmission Class) rating of roughly 50 to 55. That is enough to block normal conversation, television sound, and most household noise from the adjacent unit. For a bedroom, that means better sleep quality in addition to fire safety. The fire code and your sleep quality are pulling in the same direction here.

Administrative Monetary Penalties for Violations

Ontario Regulation 260/25, which also came into effect January 1, 2026, gives municipalities the authority to issue Administrative Monetary Penalties (AMPs) for fire code violations. This is a significant change in enforcement.

What AMPs Mean

Previously, fire code enforcement typically progressed through inspection, orders to comply, and eventually prosecution through the courts. AMPs give municipalities a faster, more direct enforcement tool. Think of them like parking tickets for fire code violations: the municipality can issue a fine without going through the full court process.

The Penalty Amounts

• Corporations (first offence): Up to $500,000
• Corporations (subsequent offences): Higher amounts at the municipality's discretion
• Individuals, including directors: Up to $50,000, with possible imprisonment for serious violations

For Brantford landlords, this means non-compliance with fire code requirements (missing CO alarms, faulty smoke alarms, inadequate fire separations, blocked exits) can result in direct financial penalties much faster than the old process of repeated inspections and court orders. The municipality does not have to wait for a fire to happen to levy a fine.

Mass Timber Protective Covering Maintenance

This one applies to a smaller group of buildings, but it is worth knowing about if you live in newer construction. Ontario Regulation 87/25 adds maintenance requirements for mass timber encapsulation materials in buildings constructed under the recent tall wood building provisions.

Mass timber buildings (using cross-laminated timber, glulam, or similar engineered wood products) achieve their fire ratings partly through protective coverings, typically layers of gypsum board or other non-combustible material that encapsulate the wood structure. Under the 2026 fire code:

• Protective coverings on mass timber elements must be kept intact
• Damage, wear, or missing fire-resistant layers are now classified as maintenance deficiencies that must be repaired
• Building owners are responsible for inspecting and maintaining these coverings

While most Brantford residential buildings are traditional wood-frame construction, mass timber is increasingly used in mid-rise residential projects across Ontario. If you live in a newer mid-rise building with exposed or encapsulated timber structure, your building management should be aware of these new maintenance obligations.

Retirement Homes and Care Facilities

O. Reg. 87/25 includes strengthened fire safety requirements for retirement homes and care occupancies. Given Brantford's growing seniors population, this is relevant for families helping aging parents with housing decisions.

Key Changes for Retirement Homes

• CO alarms are now required in retirement homes even in older buildings that previously may have been grandfathered under earlier code editions
• CO alarms required in suites adjacent to service rooms containing fuel-burning appliances
• Stricter installation requirements recognizing that residents may require assistance evacuating during an emergency
• Updated fire alarm inspection standards (ULC-S536 and ULC-S537) apply to all care facilities

If you have a parent or family member in a retirement home in Brantford or the surrounding area, it is reasonable to ask the facility management about their compliance with the 2026 fire code changes. A well-run facility will have already updated their fire safety plan. If they have not, that tells you something worth knowing.

Brantford Landlord and Renovator Checklist

Whether you are a landlord bringing a rental property up to code or a homeowner renovating a bedroom, here is a practical checklist based on the 2026 fire code changes:

Where Mattress Safety Meets Fire Code

At Mattress Miracle, we think of bedroom safety as concentric rings. The mattress is the centre. Around it are the alarms, the fire-rated walls, the escape routes, and the building systems that protect you while you sleep. Each ring matters.

Every mattress we sell meets or exceeds Canadian federal flammability requirements. But a fire-resistant mattress in a bedroom without working smoke and CO alarms is only doing half the job. And code-compliant alarms in a room with a decades-old mattress that predates modern flammability standards is the same problem from the other direction.

When customers come in and tell us they are renovating a bedroom, adding a secondary suite, or setting up a rental unit, we talk about the mattress first (that is what we know best), but we also ask about the room itself. Are the alarms current? Is the fire separation done? Are there working CO detectors on every floor?

It is not our job to inspect your home. But it is the kind of conversation a family-owned store has with its neighbours, because we would rather you be safe than just well-rested. Ideally, both.
