Ontario is in the midst of a disturbing increase in fires associated with lithium-ion batteries, leading to desperate pleas from firefighters and other officials. The Honourable Jon Pegg, the province’s Fire Marshal, emphasized the deadly challenge that these fires pose to fire services. He further pointed out that lithium-ion batteries are proliferating in consumer products such as smartphones and power tools as well as e-bikes and scooters.
Toronto fire statistics recently disclosed by city officials show a remarkable 160 percent rise in lithium-ion battery related fires in Toronto over the last three years. In just 2025, the city received 40 reported instances of these fires, leading to fear and distrust of the city’s motives by affected residents. Pegg remarked on the unique hazards associated with these batteries, stating, “Lithium-ion batteries are not like regular batteries.”
Danger increases when users replace original equipment with uncertified chargers or third-party batteries. Yet such practices work to subvert the suite of safety designs that are built into safety lithium-ion batteries. Shortly thereafter, Pegg released a statement warning of battery failure. He illustrated how these failures can cause a fast chain reaction, creating in seconds a very hot fire that jumps from vehicle to vehicle. This quick increase is highly dangerous, since the fire’s intensity can create choking black smoke that makes it even more difficult to escape.
Pegg’s officials cautioned that you should never use a charger or battery other than the one that was packaged with your device. Don’t ever replace them with untested or counterfeit replacements. This guidance is a positive step toward ensuring the devices are used according to manufacturer specifications and risks from battery failure are minimized.
As a recap of lithium-ion battery fire reality, this is an ever-increasing challenge for fire services throughout Ontario. As these batteries become more integrated into daily life, public awareness and adherence to safety protocols are essential to prevent further incidents.
