Flood mapping

Natural disasters are increasing in frequency and severity. Flooding is Canada’s most costly natural hazard, resulting in over $2 billion in insured catastrophic loss every year. Floods can happen in any season, whether from heavy rain, rapid snowmelt, ice jams, coastal storm surges, or strong onshore winds.

Flood maps help people understand where flooding may occur. They support land-use planning, emergency preparedness, response and mitigation efforts, and give residents and property owners the information they need to make informed decisions about flood risk.
