A 3 month power outage is far beyond normal planning. Here is what it would mean for food, water, heat and safety, and what is realistic to prepare.
- No official notice predicts a 3 month outage. Normal outages last hours to days.
- The Government of Canada plans for at least 72 hours; longer plans are personal choices.
- Water, food, heat and medication are the limits. Build in steps, week by week.
A 3 month outage is an extreme case. We found no official forecast of one, and normal outages last hours to days. If you still want a plan, think in stages.
What officials say
The Government of Canada says to be ready for at least 72 hours. Longer planning is up to you. For the news behind 90 day stories, see the 90 day warning explained.
What runs out first
- Water: about 4 litres per person per day adds up fast. See how much to store.
- Fresh food: use perishables first, then shelf stable. See 30 day food plan.
- Medication: plan with your pharmacist.
- Heat in winter: the hardest problem.
A staged plan
- Week 1: the 72 hour kit.
- Weeks 2 to 4: a month long outage.
- Beyond: community, water sources and trade. See week two.
