Mississauga residents are being urged to pay attention to how they charge everyday devices after lithium-ion battery-related fires increased by 122 per cent in 2025 compared with the previous year, according to a City of Mississauga news release.

Mississauga Fire and Emergency Services (MFES) has identified the batteries as the city’s fastest-growing source of ignition. The department is making safe charging the focus of its local Fire Prevention Week campaign, running October 4 to 10.

The warning applies to a wide range of items residents may have at home, including cell phones, laptops, tablets and power tools. Lithium-ion batteries also power e-bikes and e-scooters.

These batteries pack substantial energy into a compact space. The city says they can pose a danger when damaged, used incorrectly or charged improperly.

According to the city, fires involving lithium-ion batteries can ignite abruptly, spread rapidly and be difficult to put out. This year’s campaign centres on charging habits that can lower the risk of those fires.

Fire safety outreach continues this week

MFES members are taking part in community events across Mississauga during Fire Prevention Week. Residents can meet fire service public educators, ask questions and learn about practical measures they can take at home.

Registration is not required for the community appearances. The outreach is intended to help residents understand fire risks and the everyday actions that can help prevent an emergency.

The battery focus reflects a broader concern among fire services across North America, the city says. As rechargeable batteries become more common in homes, workplaces and transportation devices, departments are responding to more fires involving them.

Fire Prevention Week is an annual public education campaign observed across North America. Alongside preventing fires, it encourages residents to revisit emergency plans and refresh their knowledge of what to do if a fire occurs.

With temperatures cooling and people spending more time indoors, MFES is also encouraging residents to review fire safety basics. The city’s message includes learning how to use, charge and store battery-powered devices safely.
