Health Canada Weighs New Lithium-Ion Battery Rules as Thermal Runaway Risks Rise

On August 21, 2026, Discover Airdrie reported that Health Canada is actively evaluating new regulatory measures for lithium-ion batteries — a development that carries significant implications for Canadian businesses, commercial property managers, safety compliance officers, and everyday consumers. As lithium-ion batteries power everything from e-bikes and power tools to industrial equipment and energy storage systems, the federal government's attention to this risk signals a turning point in how Canada approaches lithium battery fire safety.

This article breaks down what the proposed regulatory review means, why lithium-ion battery fires present unique hazards, and what proactive steps organizations and property managers can take right now — before regulations are finalized and before an incident occurs.

What Health Canada Is Evaluating — and Why It Matters

According to the August 21, 2026 report from Discover Airdrie, Health Canada is weighing new rules governing lithium-ion batteries in response to growing concerns about fire and safety risks associated with battery failures. A key data point cited in the report: failing lithium-ion batteries can reach temperatures of up to 537°C during thermal runaway events — a figure that underscores why standard fire-response approaches are often inadequate.

While the regulatory process is still in its evaluation phase, the direction is clear. Federal scrutiny of lithium-ion battery safety is intensifying, and Canadian businesses that wait for final rules before acting may find themselves behind on compliance, insurance requirements, and — most critically — incident preparedness.

For commercial property managers overseeing multi-tenant buildings, warehouses, or facilities where batteries are charged or stored, and for business owners managing fleets of battery-powered equipment, this is the time to assess your current lithium battery safety posture.

Why Lithium-Ion Battery Fires Are Different

Not all fires behave the same way, and lithium-ion battery fires are among the most technically challenging to manage. Understanding the underlying mechanism — thermal runaway — is essential for anyone responsible for fire safety planning.

What Is Thermal Runaway?

Thermal runaway is a self-reinforcing chain reaction that occurs when a lithium-ion battery cell overheats. As internal temperature rises, chemical reactions accelerate, generating more heat, which in turn drives further reactions. Once initiated, this process can be extremely difficult to interrupt.

During a thermal runaway event, a battery can release flammable and toxic gases, generate intense heat reaching up to 537°C in severe cases, and in some circumstances, reignite after appearing to have cooled. The reignition risk is particularly important for property managers and first responders: a battery that appears extinguished may not be safe to leave unattended or store indoors without appropriate precautions.

Why Standard Fire Extinguishers May Be Insufficient

Conventional fire extinguishers are designed for common fire classes — ordinary combustibles, flammable liquids, or electrical fires. Lithium-ion battery fires involve a fundamentally different chemical process. Cooling the battery cells and interrupting the thermal runaway reaction requires agents specifically formulated for this purpose. This is why lithium-ion battery fire prevention planning increasingly includes purpose-built suppression equipment rather than relying solely on general-purpose extinguishers.

It is worth noting that battery fire behaviour varies depending on battery chemistry, size, state of charge, and physical condition. Not every lithium-ion battery fire will behave identically, and no single piece of equipment guarantees complete extinguishment in all scenarios. A layered approach to preparedness — combining prevention, detection, appropriate equipment, and trained response — remains the most defensible strategy.

Who Is Most at Risk in Canada

The regulatory review and the underlying fire risk are relevant across a wide range of sectors, but certain groups face heightened exposure.

Commercial property managers overseeing office buildings, condominiums, warehouses, or mixed-use developments are increasingly responsible for spaces where tenants charge e-bikes, e-scooters, power tools, and other battery-powered devices. Without clear policies and appropriate equipment, a single battery failure in a common area or storage room can escalate rapidly.

Business owners and fleet operators managing battery-powered vehicles, forklifts, or equipment face both operational and liability considerations. A thermal runaway event in a charging bay or storage area can result in significant property damage, business interruption, and regulatory scrutiny.

Safety compliance officers navigating evolving national standards need to stay ahead of Health Canada's regulatory direction. Proactive documentation of safety measures, equipment procurement, and staff training positions organizations well for whatever compliance requirements emerge.

Residential consumers — particularly those with e-bikes, e-scooters, or home energy storage systems — are not exempt from risk. Many residential fires involving lithium-ion batteries have occurred during overnight charging, often in confined spaces with limited ventilation.

Prevention and Preparedness: Practical Steps You Can Take Now

Regardless of where final regulations land, the following practices reflect sound lithium battery storage safety and are consistent with guidance from fire safety authorities and manufacturers.

Use the correct charging equipment. Always charge lithium-ion batteries with the charger supplied or approved by the manufacturer. Third-party chargers that do not match the battery's voltage and current specifications increase the risk of overcharging and cell damage.

Inspect batteries regularly. Before charging or use, visually inspect batteries for swelling, deformation, cracks, or signs of heat damage. A swollen battery is a warning sign that should not be ignored — remove it from service and follow manufacturer or local disposal guidelines.

Charge in appropriate locations. Avoid charging batteries in confined spaces, near combustible materials, or in areas without adequate ventilation. Where possible, charge during attended hours rather than overnight or when a space is unoccupied.

Store batteries properly. Batteries not in regular use should be stored at a partial state of charge in a cool, dry location away from flammable materials. For higher-risk applications, purpose-built lithium battery storage safety enclosures or cabinets can provide an additional layer of protection.

Follow manufacturer instructions and local guidelines. Manufacturer documentation and local fire codes provide the baseline for safe battery use. Where local guidelines have not yet caught up to the pace of battery adoption, consulting with a qualified fire safety professional is a reasonable step.

Fire-Response Considerations: Planning Before an Incident

Prevention reduces risk, but it does not eliminate it. Organizations responsible for spaces where lithium-ion batteries are present need a fire-response strategy that accounts for the specific characteristics of lithium-ion battery fire events.

Specialized Lithium-Ion Fire Protection Equipment

A growing category of purpose-built equipment has been developed specifically for lithium-ion battery fire scenarios. These include:

AVD lithium-ion battery fire extinguishers use Aqueous Vermiculite Dispersion (AVD) — a water-based agent containing vermiculite particles — designed to cool battery cells and help interrupt thermal runaway. AVD extinguishers are increasingly specified for environments where lithium-ion batteries are charged or stored. As with any fire suppression equipment, effectiveness depends on the specific scenario, battery size, and how quickly the extinguisher is deployed.

AVD fire blankets are designed to be placed over a battery or device experiencing thermal runaway to help contain heat, flames, and gases. They are particularly relevant for smaller battery-powered devices such as e-bikes, e-scooters, and power tools, and can be a practical addition to a lithium battery fire protection kit in commercial or residential settings.

Lithium battery suppression and storage protection equipment — including purpose-built storage cabinets and containment systems — provides a physical barrier designed to limit the spread of fire and gases in the event of a battery failure during storage or charging.

None of these products should be viewed as a substitute for a comprehensive fire safety plan, trained personnel, and working smoke and fire detection systems. They are components of a layered response strategy.

Training and Response Planning

Staff who work in environments with lithium-ion batteries should understand the signs of battery distress, know how to respond safely, and be familiar with the location and operation of any specialized fire protection equipment on site. A written response plan — reviewed and updated regularly — is a practical tool for any organization managing meaningful battery risk.

Frequently Asked Questions

What is thermal runaway in a lithium-ion battery?

Thermal runaway is a self-reinforcing overheating process in which rising battery temperature accelerates internal chemical reactions, generating more heat and potentially leading to fire, gas release, or explosion. It can be triggered by physical damage, overcharging, manufacturing defects, or exposure to high ambient temperatures.

Why can lithium-ion battery fires reach 537°C?

The extreme temperatures associated with lithium-ion battery thermal runaway result from the energy density of the battery cells and the exothermic chemical reactions that occur during failure. The 537°C figure cited by Health Canada reflects the severe heat that can be generated in significant thermal runaway events, though actual temperatures vary depending on battery size, chemistry, and conditions.

Can a lithium-ion battery fire reignite after being extinguished?

Yes, reignition is a recognized risk with lithium-ion battery fires. Even after visible flames are suppressed, battery cells may retain sufficient heat to restart the thermal runaway process. This is why monitoring, containment, and in some cases professional disposal are important steps following a battery fire incident.

What type of fire extinguisher is recommended for lithium-ion battery fires?

AVD (Aqueous Vermiculite Dispersion) extinguishers are specifically formulated for lithium-ion battery fires and are increasingly recommended for environments where these batteries are present. Standard water, CO₂, or dry chemical extinguishers may not be effective and in some cases could be counterproductive. Consult a qualified fire safety professional for guidance specific to your application.

What should Canadian businesses do now while Health Canada finalizes its rules?

Conduct a battery inventory and risk assessment, implement proper charging and storage practices, ensure appropriate fire protection equipment is available, train relevant staff, and document your preparedness measures. Proactive action now supports both safety and compliance readiness.

Is a lithium battery fire blanket effective for e-bike fires?

AVD fire blankets are designed to help contain heat, flames, and gases from smaller lithium-ion battery fires, including those involving e-bikes and e-scooters.
