Flood Forecasting & Warning

A principal mandate of the TRCA is to reduce the risk to life and damage to property caused by flooding. We do this by providing local agencies and the public with notice, information and advice so that they can respond during severe rainfall events with the potential for flooding, and during flood related emergencies. TRCA Flood Risk Management works to prepare and respond to our changing environment, the increasing needs of our municipal partners and the health and well being of our living city.
