Canada: 72-hour emergency kit explained

Public Safety Canada’s Get Prepared guidance asks households to be ready to take care of themselves for at least 72 hours after a disaster — whether you shelter in place or need to leave. This page translates the official kit lists into plain English, compares a few numbers with UK and US advice, and shows how to build the kit without panic buying.

What “72 hours” means in practice

The 72-hour window is a planning minimum so that emergency services can prioritise people who need help most. It is not a prediction that help arrives on hour 73, and it is not a call to build a bunker. Canada’s kit messaging stresses organising supplies you may already own, keeping the kit portable and easy to find, and making sure everyone in the household knows where it is — for example a backpack or wheeled suitcase in a front-hall closet.

Similar three-day framing appears in the UK Be Ready campaign. US Ready.gov talks about surviving on your own for several days, and many US planners separately discuss a shorter go-bag plus a longer stay-home store.

Water — the number Canadians see most often

Canada’s basic kit checklist lists stored or bottled water at about two litres per person per day for drinking, cooking, and hygiene. Health Canada’s emergency food and water page repeats the 2 L/person/day figure, suggests keeping some smaller bottles that are easier to handle, and notes you may want about two additional litres per person per day for cooking and cleaning when you can store them. Pets need their own water allowance.

That is lower than the UK Be Ready drinking figure of about 3 litres per person per day, and lower than Ready.gov’s roughly one US gallon (≈3.8 L) per person per day. For side-by-side litres, use water per person by country. In cold climate homes, remember that frozen pipes or a boil-water advisory can make tap water unusable even when the house still has power — bottled stores still matter.

Run the supply calculator with your household size before you buy another flat of bottles.

Food and the can opener

Official lists emphasise food that will not spoil quickly: canned goods, energy bars, and other non-perishables, plus a manual can opener. Health Canada also reminds you to plan for allergies, celiac disease, and other intolerances. If you have infants, ready-to-use formula and essential baby supplies belong in the kit; pet food belongs there too if you have animals.

The practical habit that prevents waste is pantry rotation: keep buffer food in the everyday cupboard, eat oldest first, and replace on the next shop. That matches Canada’s “build an emergency kit over time with items from your home” tone and the UK habit of adding one or two items on regular grocery trips.

Light, radio, and phones when the grid fails

Power outages are a common Canadian winter and storm scenario. Kit lists typically include:

Flashlight (torch) and spare batteries, or a crank-powered light.
Battery-operated or wind-up radio so you can hear advisories if mobile data and home internet are down.
Chargers or a power bank for phones; some official materials also mention a corded landline phone as a fallback when cordless bases have no power.

Radio standards differ by country — US households often look for NOAA weather radio features, while Canadian and UK lists emphasise a simple battery or crank FM radio. See emergency radio official specs.

First aid, medication, and documents

A basic first aid kit covers plasters, antiseptic, gloves, and similar items. Prescription medication is harder to replace during disruption — if your pharmacist and doctor allow, keep a small reserve and a written list of names, doses, and purposes. Canada’s checklist also calls for physical and digital copies of identification, an emergency plan with contacts, medical insurance information, and provincial or territorial health numbers.

Cash in small denominations helps when card networks or ATMs are down. Local emergency numbers written on paper still matter when your phone is dead.

Build it gradually — a Canadian-friendly sequence

Week 1 — Inventory: torch, radio, can opener, any bottled water and tins you already have. Put them in one labelled bag or bin.
Weeks 2–4 — Add water to reach roughly 2 L × people × 3 days; add an extra tin or dry staple each shop (pantry rotation).
Month 2 — First aid top-up, power bank, photocopies of IDs and prescriptions, pet and baby items if needed.
Every six months — Check dates, test batteries, refresh the plan. UK Be Ready uses the same six-month reminder rhythm; it travels well to Canadian households.

Shelter in place vs grab-and-go

Canada’s kit advice covers both staying home and evacuating. Keep the core kit portable. A heavier stay-home store (extra water, blankets, no-cook food) can sit in the same closet as long as you can still lift a smaller bag quickly. Compare approaches on go bag vs stay-home kit and walk a first-outage timeline on power outage: first 72 hours.

Regional hazards still matter

National checklists are a baseline. Wildfire smoke, flood, blizzard, earthquake, and extreme cold change what you add — N95-style masks, waterproof document bags, warm layers, or extra water for heat. Check your provincial or territorial emergency management site and municipal alerts for local lists. Get Prepared’s hazard pages are a useful directory for weather, climate, and infrastructure risks.

Questions people ask

Is 2 litres enough water?: It is the commonly published Canadian drinking/cooking/hygiene baseline per person per day. Official materials encourage more for cleaning when you can store it, and more still for pets or hot weather. Follow boil-water notices from local authorities.
Do I need a commercial “72-hour kit” box?: Not necessarily. Premade kits vary widely in quality. Official categories plus items you already own usually work better — especially for food you will actually eat.
How is this different from the UK or US list?: Same idea (short self-sufficiency), different water litres and radio details. Use compare government recommendations rather than copying a foreign influencer checklist.
What about apartment living?: A compact, labelled kit in a hall closet still meets the “easy to find in the dark” test. Focus on water, no-cook food, light, radio, meds, and documents before specialty gear.
