Power outages
When the lights go out.
A few simple choices make a power outage boring instead of stressful.
Power outages are one of the most common disruptions in Canada. They're usually short, but they can last longer during storms, wildfires, or grid events.
The basics are unglamorous: a flashlight you can find, a way to charge your phone, and a sense of what's safe to eat from the fridge.
Boring is the goal. A boring outage is a well-prepared one.
Before
Have these ready before you need them.
You don't need a generator. You need a handful of things that work when the wall sockets don't.
- Flashlight (not just your phone — phone batteries don't last)
- Extra batteries or a charged power bank
- A battery or crank radio for local updates
- A manual can opener
- Surge protectors for sensitive electronics
- A backup plan if you rely on medical equipment that needs power
If you use medical equipment that needs electricity, talk to your provider about a backup power plan and register with your utility's life-support program if one exists.
During
When the power goes out.
Keep the fridge and freezer closed. A full freezer can hold for about 48 hours; a fridge keeps food safe for roughly four hours if you leave it shut.
Unplug sensitive electronics to protect them from surges when power returns. Leave one lamp on so you know when the power's back.
- Use flashlights, not candles, wherever possible
- Keep fridge and freezer doors closed
- Unplug electronics; leave one light switched on
- Charge your phone in the car or with a power bank if needed
- Check on neighbours, especially older adults or anyone with health needs
- Never use outdoor grills, camp stoves, or generators indoors
After
When the power comes back.
Check food before you eat it. If something in the fridge smells off, has changed texture, or sat above 4°C for more than a couple of hours, the safe call is to toss it.
Reset clocks, timers, and anything that needs reprogramming.
