A Canadian winter storm checklist covering alerts, home, car and a 72-hour kit, so a storm or outage is an inconvenience, not an emergency.

Key takeaways
  • Check ECCC alerts, charge devices and fill fuel before the storm.
  • Cover 72 hours of water, no-cook food, light, warmth and medication.
  • Keep a winter kit in the car too.

Before the storm

  • Check Environment and Climate Change Canada alerts for your area and sign up for local alerts.
  • Charge phones, power banks and any power station.
  • Fill vehicle fuel tanks. Keep them above half in winter.
  • Bring in outdoor items, clear drains and clear snow from vents and exhausts.
  • Fill water containers and the bathtub for flushing.
  • Know where your main breaker, water shut-off and gas shut-off are.

In the home

  • 72 hours of water: at least 2 L per person per day, ideally 4 L.
  • No-cook food for 3 days or more and a manual can opener.
  • Headlamps, flashlights and spare batteries.
  • Battery or crank radio.
  • Sleeping bags, blankets, hats, gloves and wool socks.
  • Battery-backed carbon monoxide alarm, tested.
  • Prescription medications for at least a week.

In the car

  • Winter tires, working wipers and washer fluid.
  • Blanket or sleeping bag, warm clothes and boots.
  • Shovel, ice scraper, traction aid (sand or cat litter) and booster cables.
  • Flashlight, power bank, whistle and a small first aid kit.
  • Water and non-perishable snacks.

If the power fails

  • Pick one room and heat it by closing doors and layering up. See how to stay warm safely.
  • Never heat or cook with a barbecue, camp stove or generator indoors.
  • Check on neighbours who may need help, especially older adults.
  • If indoor temperatures drop near freezing, go to a warming centre or a friend's home.

Tools for a power outage

The outage planner turns your household size into water, food and battery numbers. A power station (see how to choose) is helpful if you must keep a router or medical device on.
