Flood Susceptibility Index: National Map of Flood-Prone Areas in Canada

An archived national map of flood susceptibility for Canada, predicted by an ensemble machine learning model analyzing patterns of historic flood events. The dataset is processed at a 30-meter cell size and is provided by Natural Resources Canada. It was last updated in May 2026.

Use Cases

• Prioritize regional flood risk assessment based on the national susceptibility index.
• Guide land-use planning decisions using the modeled flood-prone area classifications.
• Inform high-level environmental hazard studies with the ensemble machine learning predictions.

Strengths

• National-scale coverage for Canada.
• Data processed at a 30-meter cell size.
• Model based on patterns of historic flood events.

Limitations

• Dataset is archived; users are directed to a new collection.
• Not recommended for use at the pixel or street level due to model uncertainty.
• Column-level documentation is absent; field semantics must be inferred after download.
