Preparing for a flood
What matters most in a flood, what official guidance in Canada says, and long-life food that suits it.
In a flood, the things that matter most are important documents, insurance details, utility shut-offs, meeting point. Keep important papers on an upper floor or high shelf, away from floodwater.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
