Preparing for a power outage
What matters most in a power outage, what official guidance in Canada says, and long-life food that suits it.
In a power outage, the things that matter most are flashlight, spare batteries, charged power bank, battery or wind-up radio. Store flashlights, with batteries, somewhere easy to reach in the dark.1
What matters most
- Flashlight Essential
A flashlight for each part of the home you'd need to move around in the dark. - Spare batteries
The right sizes for your flashlight and radio. - Charged power bank
To keep a phone charged during a power outage. - Battery or wind-up radio
To hear updates if cell networks are down. - Blankets or sleeping bags
To keep everyone warm if the heating is off. - Warm clothing
Layers, hats and gloves that are easy to find. - Manual can opener
A can opener that doesn't need electricity. - Some cash
Card machines and cash points may not work in a power outage. - Plan for medication that needs a fridge Essential
Know how you'd keep it cool during a power outage. - Backup plan for powered equipment Essential

What official guidance in Canada says
- Store flashlights, with batteries, somewhere easy to reach in the dark.1
- Add a wind-up or battery radio to your kit in case the internet goes down.1
- If anyone relies on powered medical devices or medicines kept in the fridge, plan ahead for an outage.1

Allergies, dietary needs and children
Plan around everyone at home: allergies, intolerances and diets come first, and familiar food matters most for children. Recipes vary between brands, so always read the label of the product you buy.
| Food | Typical allergens | Typically suitable for |
|---|---|---|
| Canned chili | varies by recipe | check the label |
| Canned soup | varies by recipe | vegetarian |
| Baked beans | none of the main allergens in its main ingredient | vegan |
| Microwave rice pouch 250g | none of the main allergens in its main ingredient | vegan |
| Canned tuna | fish | check the label |
| Crackers | cereals containing gluten | vegan |
| Peanut butter | peanuts | vegan, gluten free |
| Dried fruit and nuts | tree nuts | vegan, gluten free |
| Granola bars | varies by recipe | vegetarian |
| Canned fruit | none of the main allergens in its main ingredient | vegan, gluten free |
Typical allergens and diets are SupKit's guide to the main ingredient, not a product's label.
- Canada names 11 priority allergens: eggs, milk, mustard, peanuts, crustaceans and molluscs, fish, sesame, soy, sulphites, tree nuts, and wheat and triticale.2
- Packaged foods must declare priority allergens and gluten sources by plain source names in the ingredient list, a 'Contains' statement, or both.3
- Companies may add a 'May contain' warning for possible cross-contamination; it is not a substitute for good manufacturing practices.3
