Toronto Fire Services Chief Jim Jessop said Wednesday that lithium-ion battery fires have increased by 36% compared to the same period last year [1].

The surge represents a critical shift in urban emergency management as these batteries become ubiquitous in consumer electronics and vehicles. Because these fires are difficult to extinguish and can spread rapidly, the trend poses a significant challenge to city infrastructure and resident safety.

As of Wednesday, Toronto has recorded 76 incidents involving lithium-ion batteries [1]. This sharp rise follows a series of back-to-back incidents that prompted the fire department to issue a public warning about the volatile nature of the technology.

"There's a 36% increase from the same time last year, with 76 of them recorded in the city as of Wednesday," Jessop said [1].

The fire chief said that the current trajectory of these incidents is not merely a statistical increase but a systemic threat to the municipality. He identified the trend as the most pressing danger currently facing the city's emergency services — a risk that outweighs other traditional fire hazards.

"Lithium-ion battery fires are the greatest public safety risk facing the City of Toronto," Jessop said [3].

Fire officials said that these batteries are found in a wide array of products, from e-bikes and scooters, to smartphones and laptops. When these cells fail or are damaged, they can enter a state of thermal runaway, creating intense heat and toxic smoke that is difficult for standard firefighting equipment to neutralize quickly.

Lithium-ion battery fires are the greatest public safety risk facing the City of Toronto.

The rise in lithium-ion battery fires highlights a growing gap between the rapid adoption of high-energy-density battery technology and the existing safety protocols for urban housing and emergency response. As Toronto sees a 36% increase in these incidents, the city may be forced to implement stricter regulations on battery charging in residential buildings or update building codes to require specialized fire suppression systems for battery-heavy environments.
