Canadian Communities with Lowest Flood Risk

Flood risk is one of the fastest-growing property and insurance concerns in Canada as climate patterns shift. These communities carry Low flood risk exposure — and rank well on overall livability.

Scope: Canada Communities ranked: 1,565 Showing: Top 25 (Low flood risk, by NorthScore) Data: NRCan Flood Maps · StatCan PMD · CMHC
Low flood risk + high livability: All communities listed carry a Low flood risk rating in our Natural Hazards data. The ranking is ordered by NorthScore — our composite livability index. Communities that score well on both livability and flood safety are concentrated in Ontario's inland suburbs, which benefit from distance from major floodplains and lack of coastal or riverine exposure.

Note: Flood risk assessments are based on NRCan flood mapping data, which may not reflect all local drainage, stormwater, or climate-change-driven flood risks. Climate change is shifting flood patterns faster than mapping data updates. Properties near waterways may carry unmapped risk not captured in this rating.
