Ganaraska Conservation

DYK? It’s been 72 years since Hurricane Hazel devastated the Toronto region. 🌊 In just 48 hours, 285 mm of rain fell, causing catastrophic flooding and the loss of lives, homes and communities. Hurricane Hazel became a catalyst for stronger planning and regulatory measures to reduce flood risk and help prevent future tragedies.

Today, Conservation Authorities use comprehensive watershed data, floodplain mapping and other science-based tools to help inform safe development, reduce risk and protect people and property from flooding.

Follow along this fall as we share more about how your local Conservation Authority helps communities plan ahead, supports projects and reduces the risk of natural hazards across Ontario.
