Batteries are catching fire all over Toronto and Fire Chief warns to take risk seriously

Toronto Fire Services (TFS) is warning residents about the growing safety risks of lithium-ion batteries after several fires occurred in the city just this past day.

In a statement posted to X on Monday morning, Fire Chief & General Manager Jim Jessop said that crews had responded to three separate battery-related fires within 24 hours.

In 24 hrs, our crews have responded to 3 lithium-ion battery fires. These fires burn hot, fast, and can spread rapidly. Be aware of the potential risks, take them seriously, follow safety guidelines, and stay safe. It helps protect you and our first responders. #Toronto pic.twitter.com/VyKurr7rEx

These batteries can be found in numerous household items, including smartphones, laptops, e-readers, and even some cordless vacuums, portable fans and rechargeable flashlights. They can overheat if charged for too long or not stored properly.

Halfway through 2025, TFS reported responding to 43 fires caused by lithium-ion batteries, including one in a Toronto high-rise, where a "large quantity" of lithium-ion batteries were discovered within the unit. 

These batteries can also be found in e-bikes and e-scooters, which pose significant risks. In response to a 2023 fire on a Toronto subway train, the TTC has implemented a seasonal ban on e-bikes during the winter months. 

Power-assisted bicycles are not permitted on TTC vehicles and property from November 15 to April 15 each year. Instead, they can be parked at or near subway station entrances, or stored in bike lockers at most subway stations. 

Electric wheelchairs and other devices used by people with mobility issues, however, will continue to be allowed on the TTC as they do not pose a safety or fire risk.

The City is advising residents to use lithium-ion batteries safely by only using certified, manufacturer-approved batteries, avoiding charging them unattended, and discontinuing use if they emit a strange odour, become deformed, overheat, or leak.
