February 2021

This report examined the preparedness of 16 major Canadian cites to minimize the negative consequences of current and future floods. It is the intent of this report to provide an informed perspective that will contribute to the alleviation of current and future flood and climate-related risks in Canada.

With spring around the corner, Canadian cities score an uninspiring C+ on flood preparedness 

  • Six cities—including some that experienced severe floods in recent years—were slightly less prepared for flooding in 2019/20 than they were in 2015. 
  • Comprehensive and up-to-date flood maps, supported by funding from Public Safety Canada, should be mandatory for a city to qualify for federal flood-recovery aid, according to municipal managers. 
  • Only half of the 16 cities assess the potential for municipal stormwater to back up into basements, even though basement flooding is the No. 1 catastrophic cost to homeowners and insurers. 

Municipal officers repeatedly warned that cities must do a better job of preparing for floods, or risk another spring of sandbagging, generally at the last minute. 

There is some positive news: Edmonton, Regina and Toronto improved their flood-preparedness scores, each achieving a B+, primarily for protecting health-care facilities such as hospitals, clinics and retirement homes.  These cities also put in place measures to maintain continuity of electricity, telecommunications, water and wastewater services during floods.  Edmonton also provides free flood-risk assessments for homeowners through its municipally owned utility, EPCOR. It is the only city to do so. 

“Flood-readiness is key to societal resilience,” said Veronica Scotti, Chairperson Public Sector Solutions, Swiss Re and Intact Centre Advisory Council member. “By learning from one another, these cities could make much-needed progress on climate resilience. This would include maintaining a city-level risk management framework and outcome-oriented adaptation plans.”

Last year, insurable losses in Canada reached $2.5 billion, making 2020 the fourth-worst year for insurable claims since record keeping began in 1983. Climate change, aging municipal infrastructure and residential housing, and the accelerating loss of protective natural infrastructure such as wetlands contribute to flooding and the rising costs to governments, businesses and homeowners.
