‘This is Your Warning’ campaign urges Canadians to charge safely amid surge in battery-related blazes

TORONTO – NATIONAL NEWS – The growth of lithium ion batteries continues. These are the powerful little power packs that run electric vehicle, e-bikes, and many of the devices we count on everyday.

Toronto Fire Services (TFS) has launched its second-annual “This is Your Warning” campaign today, following a dramatic surge in fires linked to lithium-ion batteries. The campaign comes as a response to alarming new data showing a 38 per cent year-over-year increase in such fires across Canada’s largest city.

In 2024, TFS responded to 76 fires caused by lithium-ion batteries, up from 55 in 2023 and just 29 in 2022 — marking a 162 per cent increase over two years.

The urgency of the message is underscored by a recent high-rise blaze that injured multiple residents and firefighters. A subsequent investigation revealed a large quantity of lithium-ion batteries in the affected unit, which contributed significantly to the fire’s intensity and smoke spread.

Common Devices, Uncommon Dangers

Lithium-ion batteries are found in everyday devices like smartphones, laptops, power tools, e-bikes, scooters, and children’s toys. While generally safe, they pose serious fire risks if they are damaged, improperly charged, or tampered with. TFS notes that many recent fires were linked to residents modifying or trying to extend the life of old or incompatible batteries.

“We’re seeing a concerning rise in fires caused by lithium-ion batteries, many of which are preventable,” said Jim Jessop, Chief and General Manager of Toronto Fire Services. “This campaign is about giving residents the knowledge they need to stay safe. Fire prevention is a shared responsibility.”

Essential Safety Tips

Toronto Fire urges residents to follow these safety practices:

• Always monitor lithium-ion batteries while charging

• Do not modify or tamper with batteries

• Use only certified, manufacturer-approved batteries and chargers

• Discontinue use and contact the manufacturer if the battery shows signs of:

  • Strange odours

  • Discolouration

  • Excessive heat

  • Swelling or leaking

  • Unusual noises

Residents should safely dispose of damaged or old batteries at City Drop-off Depots or during Community Environment Days.

Relevance Beyond Toronto

This growing fire risk isn’t limited to the GTA. Thunder Bay and Northwestern Ontario residents are increasingly adopting e-bikes, scooters, and portable electronics, many powered by lithium-ion batteries. With increased adoption comes increased risk — making these safety tips relevant nationwide.

Whether at home, in apartments, or on the move, Canadians are urged to take battery safety seriously to prevent avoidable tragedies and protect first responders.
