Historical Flood Events

Floods have affected communities across Canada for centuries. Indigenous people have passed on the knowledge of flooding through oral histories, stories, and song (traditional knowledge). More recently, the flood events have been documented in newspaper articles, reports, and other written publications.

The Historical Flood Events layer brings together over 1,400 publications of floods in more than 7,000 locations since 1696. This is a unique compilation of Canada’s flood history. Precipitation statistics are available for flood events caused by heavy rain and coastal storms from January 1, 1980 onwards.
