Active Floods in Canada

Flood extent polygons representing active floods throughout Canada as monitored by Natural Resources Canada using satellite imagery for emergency response.

In response to large flood events, Natural Resources Canada, for the provision of emergency geomatics services (NRCan), may be activated by Canada’s emergency management protocols. As new satellite imagery becomes available, NRCan will extract flood extent polygons and update the dataset in near real time (4 hours). This item contains the latest flood products generated in the past three days. For any data older than 72 hours, please refer to the Floods in Canada - Current Year entry.

The flood products are generated and validated on a best effort basis. Various factors may affect the quality of the flood polygons. Those factors include but are not limited to: sensor type, image resolution, cloud coverage or limits to the flood polygon extraction method. In this layer, a symbology is applied to the flood polygons based on the underlying land use classification, when available, or is simply unclassified and shows the gross flood extent otherwise. Filter on dates and Area of Interest (AOI) to view specific products. Time-enabled on Date UTC field. ".zip" file packages that contain the shapefile, PDF map, and ".kmz" of individual product items are available through the FTP links listed in the Package URL field.

Disclaimer:

Emergency response authorities are the primary users of these satellite-derived open water flood extent map products. These products are generated to provide analysis and emergency response situational awareness and to facilitate decision-making during major flood events. The open water flood extent products are generated rapidly and limited time is available for editing and validation. The flood products reflect the open water flood conditions at the date/time of acquisition. While efforts are made to produce high quality products, near-real time products may contain errors due to the limited time available for vector editing and validation. Please note that current algorithms do not map flooded areas under the forest canopy and are not optimized for urban flood mapping.
