| Map detail | Why it changes the answer |
|---|---|
| hazard or flood zone | For the Canadian flood-map review, match the property, parcel, or coordinates |
| map owner | In the Canadian flood-map review, identify the mapped hazard, scenario, and source owner |
| effective or study date | Before relying on the Canadian flood-map review, use the effective or study date when comparing maps |
| local study or map-change record | Keep the panel, study, layer, and local-authority link with the Canadian flood-map review |
Use Canada flood map by address as mapped evidence for its stated hazard, date, and purpose, not as a promise that flooding will or will not occur or as a final insurance quotation.
If the property is outside the visible study
Check the local floodplain, planning, drainage, emergency-management, or water authority when the national map has no detailed layer.
For flood risk for the Canadian property, ask the map owner which current study applies; absence from one viewer is not evidence that the property has no flood risk.
