Canada sees surge in lithium‑ion battery fires in Calgary and Toronto

Fire officials in Calgary report that lithium‑ion battery fires linked to e‑scooters and e‑bikes have nearly doubled from 2024 to 2025, causing more than $30 million in damage. Fire Chief Steve Dongworth warned that overcharging, cheap offshore batteries, physical damage and modifications that increase power push devices beyond their design, leading to explosive fires and toxic vapours. He urged residents to use certified batteries, avoid charging in hallways, and recycle batteries at approved depots.

In Toronto, Fire Chief Jim Jessop highlighted a growing public‑safety concern after the city responded to 90 lithium‑ion battery fires in 2025, including recent incidents at a recycling facility and an e‑bike shed that resulted from thermal runaway. Jessop emphasized the risk to firefighters and the public, urging the use of manufacturer‑approved batteries and chargers, and cautioning against unattended charging or damaged cells. Both cities stress the need for proper storage, charging practices, and disposal to prevent further incidents.
