If you searched "90 day blackout Canada", you probably want two answers: is it real, and what should I do. Short version: the 90-day figure came from a US military planning story, no Canadian authority has issued a 90-day warning, and a few cheap steps cover the outages that actually happen. Details are on our 90 day blackout warning page and in could Canada have a 90 day power outage.

Five steps worth taking this week

  1. Store water. Official guidance is at least two litres per person per day for at least three days. Add extra for cooking and washing. See how much water to store.
  2. Stock no-cook food. Cans, crackers, peanut butter, dried fruit and a manual can opener. See emergency food kits.
  3. Charge a backup battery. A power bank keeps phones alive. A power station runs a router, lights and a laptop. Size it with the sizing guide.
  4. Set up safe heat and light. Flashlights and headlamps, plus a plan to heat one room. See heating one room safely.
  5. Write down a plan. Where you would go if the outage lasted a week, and who to call. See what to do if the power is out for a month.

How far to go

For most households, two weeks of supplies is the sensible limit. If you want a full 90 days, use the supply list and the 90 day plan to build in stages.

Safety: never run a generator, barbecue or camp stove indoors or in a garage. Carbon monoxide has no smell.
