Ottawa fire crews are sounding the alarm on lithium-ion battery safety following a fire in the Stittsville neighbourhood that has reignited concerns about the hidden dangers lurking in everyday devices.
The blaze, which prompted Ottawa Fire Services to issue a public warning, is part of a troubling pattern that fire officials say is becoming increasingly common as battery-powered products — from e-bikes and scooters to power tools and laptops — fill more Ottawa homes than ever before.
What Makes Lithium-Ion Batteries So Dangerous?
Lithium-ion batteries pack a serious punch of energy into a compact space, which is exactly what makes them so useful — and so risky. When they fail, they can enter a state called "thermal runaway," where heat builds rapidly and uncontrollably, leading to fires that are notoriously difficult to extinguish and can reignite hours later.
The batteries most likely to cause trouble are those that are damaged, counterfeit, improperly charged, or simply old and worn out. Ottawa Fire Services has seen fires sparked by everything from cheap replacement batteries ordered online to devices left on chargers overnight.
Tips Ottawa Fire Services Wants You to Know
Ottawa fire officials are urging residents to follow some key safety steps:
- Only use the charger that came with your device — or one certified by the manufacturer. Off-brand chargers are a leading cause of battery failures.
- Never charge devices overnight or while you're sleeping. If a fire starts while you're asleep, you may not have time to react.
- Don't charge or store batteries in hot environments — avoid direct sunlight, cars in summer, or near heat sources.
- Watch for warning signs — swelling, unusual heat, hissing sounds, or a strange smell are all red flags that a battery may be failing.
- Store e-bikes and e-scooters safely — don't block exits or keep them in sleeping areas. These larger batteries carry higher risk.
- Check for recalls — if you own a battery-powered product, especially an e-bike or scooter, verify it hasn't been recalled through Health Canada's database.
A Growing Problem Across Ottawa
The Stittsville fire is far from an isolated incident. Fire departments across North America — including Ottawa — have reported a steady climb in lithium-ion battery-related fires over the past several years, tracking directly with the explosion in popularity of e-bikes, electric scooters, and other high-capacity battery devices.
New York City, for example, declared the issue a public safety crisis after dozens of deaths linked to e-bike battery fires. Ottawa hasn't reached that scale, but fire officials are keen to get ahead of the problem before it escalates.
If a lithium-ion battery fire does break out in your Ottawa home, Ottawa Fire Services says to evacuate immediately and call 911 — do not attempt to fight the fire yourself, as water may not be effective and the battery can reignite unpredictably.
What To Do With Old Batteries
Don't throw old or damaged lithium-ion batteries in the trash or blue bin — they can ignite in garbage trucks or recycling facilities. Ottawa residents can drop off batteries at the city's Household Hazardous Waste depots at Trail Road or the Vars landfill.
With battery-powered devices becoming a fixture of everyday Ottawa life, a few simple habits could make the difference between a close call and a catastrophe.
