Flood Mapping
Canadian federal, provincial and territorial geospatial data providers are collaborating to provide tools and resources to help Canadians plan and prepare for floods.
About Flood Mapping in Canada
Flooding is Canada’s most common and most costly natural disaster. Overall, the estimated average annual cost of residential flooding in Canada is $2.9 billion. Natural disasters are increasing in frequency and severity. For more information, please visit: Adapting to Rising Flood Risk.
Learn About Flood Mapping
Flood maps show an area that may be covered by water, or show where the water reaches during a specific flood event. They are critical tools that can help us identify potential risks and mitigate flood impacts.
Flood Mapping and the Government of Canada
The Government of Canada is investing to help Canadians better plan and prepare for future floods. Learn how the Government of Canada contributes to the production of flood maps.
