Check whether a property is located in a flood zone or in a channel migration zone of a watercourse

You can check whether a property is located in a flood zone or in a channel migration zone of a watercourse.

The interactive map presents two types of information on the flood zones currently in effect:

The sectors for which former generation flood zone maps are available from municipalities or municipalities or regional county municipalities (RCMs);
The identification of flood zones on the new-generation maps. As soon as a new-generation map is published for a sector, it replaces the former generation map.

New-generation maps

The new-generation maps will be published gradually starting in spring 2026.

Enter your address or your lot number in the search bar below to obtain information on a property.

You can also navigate the interactive map to find the sector you are interested in.

If you encounter a technical problem with the interative map, contact the Client Relations Centre (French only).

To obtain more information about the new-generation maps, complete the information request (French only).

To obtain more information about the former generation maps and improvement work you intend to carry out in a flood zone, contact your municipality or the RCM (French only).
