The MNR provides flood forecast messages to conservation authorities and municipalities to enable them to prepare for, track and manage local flooding. Flood forecast messages are not flood warnings.

Your local conservation authority (CA) is responsible for local flood messaging and your local municipality is responsible for on the ground flood response. For more information on your local situation, check with your conservation authority or municipality. If you live in a community that is not serviced by a conservation authority, any flood advisories or flood warnings in your area are issued by the nearest MNR district office. Who to Contact

Provincial Messages

Local Messages

In Ontario, there are two main types of messages Local Messages and Provincial Messages that are issued by various organizations. Local Messages are issued by conservation authorities (CA) or MNR districts in areas that are not serviced by CAs. Provincial Messages are broader, high level messages that are issued by MNR’s Surface Water Monitoring Centre to local agencies and partner minisiries to alert them to the potential flooding.
