Toronto's Lithium-Ion Battery Fire Crisis: What Canadian Facility Managers Need to Know Now

On August 18, 2026, the Ontario Association of Fire Chiefs and Toronto Fire Services issued a stark warning: lithium-ion battery fire incidents in Toronto are on track to reach a record high. Toronto Fire Chief Jim Jessop underscored the severity of the threat, noting that thermal runaway can drive a room to flashover in approximately 90 seconds — a timeline that fundamentally changes how commercial and residential property managers must think about fire preparedness.

For facility directors, building owners, and occupational health and safety officers across Canada, this is not a distant headline. It is an operational risk that demands immediate, informed attention.

What the August 2026 Report Reveals

The August 18, 2026 report from the Ontario Association of Fire Chiefs and Toronto Fire Services documents a clear and accelerating trend: lithium-ion battery-related fire incidents are increasing year over year, with 2026 projections surpassing previous records. Chief Jessop's public statements reflect a growing consensus among fire safety professionals that the proliferation of lithium-ion batteries — in e-bikes, electric vehicles, energy storage systems, and consumer electronics — has outpaced the fire safety infrastructure in many Canadian buildings.

The 90-second flashover figure cited by Chief Jessop is particularly significant. Traditional fire response planning often assumes a longer window for evacuation and suppression. When a single battery cell enters thermal runaway and cascades through a pack, that assumption no longer holds. For multi-unit residential buildings, commercial warehouses, and facilities with EV charging infrastructure, the margin for error has narrowed considerably.

Why Lithium-Ion Battery Fires Behave Differently

Understanding why these fires are so difficult to manage begins with the chemistry. Lithium-ion batteries store a substantial amount of energy in a compact form. When a cell is damaged, overcharged, or exposed to excessive heat, it can enter a self-sustaining exothermic reaction known as thermal runaway. Unlike conventional fires, thermal runaway generates its own oxygen internally, meaning the reaction can continue even in low-oxygen environments and can reignite hours after an apparent suppression.

The heat generated during thermal runaway is intense and rapid. Gases released — including hydrogen fluoride and other toxic compounds — add a chemical hazard dimension that standard fire response protocols are not always designed to address. This is why conventional water application or generic ABC dry-chemical extinguishers often prove insufficient: they may knock down visible flames without adequately cooling the battery cells driving the reaction, allowing reignition.

For industrial fire safety planning, this distinction is critical. A suppression approach that works reliably for a paper fire or a grease fire may provide only a temporary and false sense of control when applied to a lithium-ion battery incident.

Who Faces the Greatest Exposure

Commercial property managers and building owners overseeing parkades, loading docks, or common areas where tenants charge e-bikes, scooters, or personal mobility devices. The informal and often unsupervised nature of these charging activities creates significant liability and safety gaps.

Multi-unit residential building operators face a particular challenge: residents increasingly bring lithium-ion powered devices into suites and storage areas, often charging overnight without adequate ventilation or monitoring. A single thermal runaway event in a storage room or underground garage can escalate rapidly.

Corporate facilities directors and industrial operators managing battery storage zones, EV fleet charging infrastructure, or large-format energy storage systems carry the highest aggregate risk. The scale of battery installations in these environments means that a single failure can trigger a cascading incident affecting an entire facility.

Occupational health and safety officers in any sector where lithium-ion batteries are used operationally — from warehousing and logistics to healthcare and manufacturing — need to ensure that their emergency response procedures reflect the specific characteristics of these fires, not just general fire response protocols.

Practical Prevention and Preparedness Measures

Effective lithium-ion battery fire prevention is not primarily about purchasing equipment — it begins with operational discipline and informed protocols.

Follow manufacturer charging guidelines strictly. Overcharging is one of the most common triggers of thermal runaway. Facilities should establish and enforce charging time limits, use only manufacturer-approved chargers, and avoid leaving batteries on charge unattended for extended periods, particularly overnight.

Implement regular inspection protocols. Swollen, cracked, or physically damaged batteries are a clear warning sign of internal degradation. A routine inspection schedule — particularly for fleet devices, forklifts, and shared equipment — allows facilities to remove compromised batteries before they become a hazard.

Isolate charging stations from combustible materials. Charging areas should be designated, clearly marked, and positioned away from flammable storage, paper goods, textiles, and other combustibles. Adequate ventilation is essential to dissipate heat and any off-gassing that occurs during normal charging cycles.

Establish clear employee training and emergency response procedures. Staff should understand the signs of a battery in distress — unusual heat, swelling, hissing, or a distinctive acrid odour — and know exactly what steps to take, including who to notify, when to evacuate, and what suppression tools are available and appropriate. Tabletop exercises and documented response plans are a practical starting point.

Fire-Response Considerations and Specialized Equipment

When prevention fails and an incident occurs, the response tools available to your team matter enormously. Given the limitations of conventional suppression agents against thermal runaway, Canadian facility managers are increasingly evaluating purpose-built solutions designed specifically for lithium-ion battery fires.

AVD-based fire extinguishers represent one category of specialized suppression technology developed with lithium-ion battery fires in mind. AVD (Aqueous Vermiculite Dispersion) formulations are designed to cool battery cells rapidly and coat them to help interrupt the thermal runaway cycle. LithiumSafe Fire carries purpose-built options suited to a range of commercial and industrial environments, including the 6L AVD Lithium Ion Battery Fire Extinguisher for portable response, the AVD 2L Fire Extinguisher for smaller installations, and the AVD 50L Wheeled Lithium Ion Battery Fire Extinguisher for high-risk industrial zones. For facilities seeking a ready-to-deploy solution, the AVD Fire Suppression Kit bundles key components into a single package.

Specialized fire containment blankets offer another layer of response capability, particularly for smaller battery packs such as those found in e-bikes, power tools, and consumer electronics. The Lithium Battery AVD Fire Blanket can help contain a burning battery, limit the spread of flames and toxic gases, and buy critical time for evacuation and emergency services response. It is important to note that no single suppression tool guarantees complete control of every lithium-ion fire incident — these products are designed to support a trained response, not replace it.

Consulting with your local fire authority having jurisdiction (AHJ) is always advisable when establishing or updating a battery safety program.
