Reduce household food waste

Take a small inventory before shopping

Canada’s Food Guide recommends using the food you already have and buying what you need and will use. As a practical way to apply that advice, look through your fridge, freezer and cupboard before planning your next shop. [8][1][4]

Write a short inventory: what is available, which fresh ingredients need using first, and which safely stored leftovers already have a date. This is a suggested household routine, not a food-safety assessment. [8][1][4]

• Choose a visible “use first” space without changing required storage conditions.
• Check dates and labels; do not combine expiration dates with best-before dates.
• If you cannot establish a food’s storage history, do not put it into a meal just to avoid waste.

Plan a few meals with overlapping ingredients

Plan for a couple of days or a whole week—whichever fits your schedule. Think about how many people will eat, the time available to cook, and meals and snacks you actually expect to have at home. [8][4]

Choose recipes with overlapping ingredients and use fresh ingredients first. For example, you might plan two meals that both use the same fresh vegetables; the point is to give the ingredients a realistic use, not to buy extra for a perfect plan. [8][4]

• Allow for a busy day with a simpler meal.
• Use fresh, frozen, canned or dried ingredients as appropriate to the plan.
• Only plan extra cooked portions if you can cool, store and use them safely.

Turn the plan into a shopping list

Use a shared shopping list and subtract ingredients already in your inventory. Canada’s Food Guide suggests keeping a list where everyone can add to it, and planning purchases around what you need and will use. [8][3]

A suggested check before a bulk purchase or offer: will the household use it, and is there suitable storage? A larger pack is not helpful if the surplus will sit unused or cannot be kept safely. [8][3]

• List the missing ingredients for planned meals and snacks.
• Check how many people will actually be eating before deciding quantities.
• Review the list against the food at home before leaving for the shop.

Give leftovers a date and a next meal

Refrigerate leftovers promptly in shallow containers, label them with their contents and date, and eat refrigerated leftovers within 2 to 3 days or freeze them for later use. Cooked food left at room temperature for more than two hours must be discarded. [4]

Thaw frozen leftovers in the refrigerator or microwave. Reheat leftovers to 74°C using a digital food thermometer, and discard uneaten leftovers after reheating. These safety limits come before any waste-reduction goal. [4]

• Plan a specific next meal for a safely stored leftover portion.
• Reheat only the portion needed, using microwave-safe containers if applicable.
• Do not use smell or taste as a test of safety.

Prevent first; recovery is not a cure for food insecurity

ECCC’s food recovery hierarchy prioritizes prevention: prevent waste, recover suitable surplus, recycle what can be recycled, then dispose as the least-preferred option. Applied at home, planning to use food comes before routinely buying too much and hoping to donate it. [7]

Recovery of surplus food for people can preserve its value, but ECCC explicitly does not present it as a solution to food insecurity. Donation also depends on safe food and a recipient that agrees to accept it; follow the Ontario-specific donation guide rather than assuming any surplus can be dropped off. [7]

Review one recurring waste problem

Try an optional end-of-week reflection: which ingredient was repeatedly left unused, and could the next plan use a smaller quantity or a recipe that shares it? These prompts are a planning aid, not a promise of savings. [8][4]

Keep any notes privately at home. You do not need an account, tracking app or personal-data form to make a short meal plan. [8][4]

• What did our schedule change after we shopped?
• Could a smaller shop or a simpler meal have helped?
• Did we plan safe storage and a next use for the extra portions?
