Canada household resilience
Government of Canada guidance recommends being prepared to take care of yourself and your family for at least 72 hours and lists two litres of stored or bottled water per person per day.
Check provincial, territorial and local emergency-management guidance because risks and recommended additions vary by region.
Use the global resilience check
The main calculator lets you combine electricity, gas/fuel, mains water, food-supply and communications disruptions, then compares your stored water, shelf-stable food and backup phone energy with the selected planning horizon.

What limiting resilience does — and does not — mean
The headline day figure identifies the earliest modelled resource limit in the selected scenario. The secondary 0–100 scenario score summarises broader coverage. Neither is a forecast of how long it is safe to remain at home, and neither replaces emergency services, public-health guidance, evacuation orders or professional advice.
Use the same plan in your preferred units
The global calculator keeps its country guidance pack separate from display units. You can use the automatic country default or switch water quantities between litres, US gallons and UK imperial gallons without changing the underlying planning target.
What the Canadian country pack changes
The Canadian pack uses the Government of Canada two-litre-per-person-per-day emergency-kit baseline and defaults to metric display. A larger enhanced reserve can be explored, but it is labelled as a Home Resilience Check planning setting rather than federal guidance.
Provincial, territorial and municipal emergency information can add local hazard requirements. The calculator is most useful for quantifying household supplies while those local instructions determine what actions to take during an actual event.
What stays the same globally
The dependency engine, limiting-resilience calculation, device-load planner, food-usability logic, copy controls and printable plan use the same method in every supported country. Localisation changes the guidance source, water baseline, emergency references and default display units rather than creating a different product.
