Battery fires sweeping the city as lithium crisis worsens

Lithium-ion batteries are catching fire across Toronto at an alarming rate, and the city's fire chief is warning the problem is only getting worse.

This week alone, three separate battery-related fires have erupted across the city. Fire Chief Jim Jessop called them a "serious public safety concern," warning that the increasing frequency and intensity of these blazes pose a growing risk to both residents and firefighters.

The fires have sparked renewed warnings about the devices — which power everything from e-bikes and scooters to power tools and personal electronics. Officials say the batteries can ignite spontaneously, particularly when damaged, overcharged, or stored improperly. Once they catch, the fires burn intensely and are difficult to extinguish.

For Toronto residents, the takeaway is straightforward: be careful with battery storage and charging. Don't leave devices plugged in overnight. Keep batteries away from heat sources. If you see signs of damage or swelling, dispose of the battery at an e-waste facility, not the trash.

The fire service is monitoring the trend closely. This isn't speculation — it's happening now, and the city's emergency services are stretched.
