Better Flood Maps Are Required to Protect Canadians and Their Property

CIGI Policy Brief No. 154

July 16, 2019

Flooding is a growing source of financial insecurity for Canadian households. Flood maps serve a far more effective function in many countries than they currently do in Canada, and they are an essential tool with which to communicate flood risk to the public, encourage property owners to purchase insurance and encourage flood preparedness. Existing flood maps in Canada, however,  are difficult to find, outdated and of poor quality, containing few of the characteristics that experts associate with high-quality maps.

Improving information about flood exposure, by improving the quality of and access to these maps, can play an important role in protecting Canadians from significant financial risk.
