Canada flood map inventory
The Flood Map Inventory shows areas in Canada where a flood hazard map has been collected by Natural Resources Canada (NRCan). The inventory provides information on how to access these maps and does not display flood zones or extents. Depending on the license and availability status, there may be links for download, along with references to the original source and/or data owner.
NRCan collaborates with provincial and territorial governments to gather flood hazard maps from them as well as from municipalities, and other agencies responsible for flood mapping. The inventory is updated on a biannual basis.
Note: Data and maps in the Inventory can be made available upon request to federal and contributing partners.
Disclaimer
This layer represents the boundaries of maps included in the Canada Flood Map (CFM) inventory. Please note:
- The inventory does not include every flood hazard map in Canada and may be incomplete or inaccurate
- It should not be relied upon as the official source of flood mapping information
- If a map is missing, it does not mean that the area has never been mapped
For the official version of a map, updated information, or confirmation of applicable regulations, please contact the local authority responsible for flood mapping.
